Micellization Investigations of Meristyl Alcohol Based BisSulfosuccinate Gemini Surfactant with Anionic and Nonionic Conventional Surfactants Vinayika Singh*, Rashmi Tyagi Department of Chemistry, Jaypee University of Engineering and Technology, Guna, Madhya Pradesh, India

Abstract Micellization studies have been carried out to investigate the mean aggregation number of aqueous solution of newly synthesized bis-sulfosuccinate gemini surfactant based on meristyl alcohol (BSGSMA1,4) using flexible spacer as methylene chain (CH2)4. The methylene chain was introduced via α,ω-dibromo butane in the reaction. The present study explored the effect of prepared gemini toward the two well recognized conventional surfactants, i.e., sodium dodecyl sulfate (SDS) and Triton X 100 in mixed micelles of binary systems. The measurements were carried out with the help of steady state fluorescence technique. From the study, it was observed that the value of N for pure BSGSMA1,4 (3*CMC) was enhanced from N = 14 to 32 for mixed BSGSMA1,4 + SDS (3*CMC) system and suppressed (N = 12) for mixed BSGSMA1,4 + Triton X 100 (3*CMC). As concentrations of SDS (5*CMC) and Triton X 100 (40*CMC) were increased in mixed systems, the value N was also enhanced for both systems and found to be 57 and 33, respectively. The results revealed the more favorable micellization behavior of gemini BSGSMA1,4 toward the SDS as compared to Triton X 100 and also exhibited the good synergism behavior of prepared gemini with conventional anionic surfactant (SDS) even at a lower concentration, i.e., 3*CMC. Keywords: aggregation number, anionic bis-sulfosuccinate gemini surfactant, mixed systems

INTRODUCTION Gemini surfactants are the amphiphilic molecules which have two hydrophilic head groups and two hydrophobic tail groups separated by a covalently attached spacer. On the other hand, conventional surfactants represented by a single hydrophobic tail connected to an ionic or polar head group. Gemini surfactants exhibited good surface active properties like excellent surface activity, good water solubility, low CMC value, better foaming as compared to conventional surfactants. Therefore, researchers always attract toward the studies of gemini surfactants.[1] Sulfosuccinate surfactants are known as industrial consumable surfactants and used

in numerous fields such as cosmetics, textile, polymers, paints and coating, leather, printing, and agriculture.[2] The huge applications of these surfactants are mainly due to their admirable performance properties such as foaming, emulsifying, solubilizing properties, and excellent surface active properties viz. low critical micelle concentration, high effectiveness in reducing surface tension, and biodegradability.[3] Many researchers investigated the mixed surfactant study[4,5] of anionic gemini surfactants with some conventional surfactants. Fluorescence technique is widely used to determine the

Abstract Guar gum, a naturally occurring polysaccharide, is being widely used in numerous applications. Guar gum is modified by graft copolymerization to improve upon properties. Grafting is an innovative method to produce a new class of semi synthetic polymeric materials. In grafting, while the original properties of polymer remain intact, some additional and useful properties are incorporated. Natural polymers are available in huge quantities on Earth, since billions of years. Guar gum is a versatile natural polymer and is used as food and medicinal plants. In this review, an attempt is being made to bring the insights on guar gum and its graft copolymers. Keywords: Cyamopsis tetragonolobus, graft copolymers, guar gum, % grafting and grafting efficiency, polymer, polysaccharide

INTRODUCTION There has been a considerable thrust in the growth and consumption of polysaccharides such as starch, cellulose, alginate, chitosan, guar gum, etc., for variety of applications in the field of biomedical and pharmacology. This is because of their properties like sustainability, biodegradability and biosafety. The primary aim of this review article is on guar gum (GG) chemistry, its production and applications. The review article also highlights few latest developments of Guar Gum graft copolymers for different applications. GG is a naturally occurring non-ionic polysaccharide of high molecular weight (approximately 50,000–8,000,000). It is derived from the guar seed Cyamopsis tetragonolobus. This plant is grown mainly in India and Pakistan and is being used as an edible food item also. It finds

application in various industries as viscosity builder, stabilizer, emulsifier and water binder. Guar gum is a non-ionic branched chain natural polymer. It consists of straight mannose units joined by β-D (1→4) linkage having β-D galactopyranose units to this linear chain by (1→6) linkages. The ratio of mannose to galactose units ranges from 1.6:1.0 to 1.8:1.0, possibly because of climatic variation.[1–3] In cold water, guar gum forms a viscous, colloidal dispersion. It is often used as a viscosity builder and water binder in different industries like mining, textiles, paper, petroleum, explosives, etc. (Figure 1)[4] MANUFACTURE OF GUAR GUM Guar gum, known as Gum cyamopsis or guar flour, is derived from the ground

Abstract Chitosan is a natural poly-cationic linear polysaccharide derived from chitin and also known as de-acetylated chitin. It is derived from partial de-acetylation of chitin. Its low solubility in neutral and alkaline solution limits its application. Chitosan’s chemical modification brings to it new reactive functional properties for different applications. Because of biocompatibility, non-toxicity, low allergenicity and biodegradability, it is used in various applications .This review paper presents the chemistry, literature review of properties, applications and economics of production of chitosan.

INTRODUCTION Chitosan is composed of β-(1-4)-linked Dglucosamine and N-acetyl-D-glucosamine randomly distributed within the polymer. Chitosan is cationic in nature, while majority of polysaccharides are either neutral or negatively charged in an acidic environment. This property of chitosan allows forming electrostatic complexes or multilayer structures with other negatively charged natural or synthetic polymers [1]. Chitosan is reported to have various biological properties, such as antitumor [2], antimicrobial [3], and antioxidant [4] activities. The degree of de-acetylation (Molar fraction of de-acetylated units or % de-acetylation) and the molecular weight of chitosan, were found to affect its biological properties [5]. Chitosan is widely used for different biological and biomedical applications such as in water treatment [6], wound-healing materials [7], pharmaceutical excipient or drug carrier [8], obesity treatment [9] and as a scaffold for tissue engineering [10]. There is increased interest in pharmaceutical as well as biomedical applications of chitosan

and its derivatives and significant development has been achieved.

Fig.1: Chemical structures of cellulose, chitin, and chitosan [11] Different Structural Conditions of Chitosan [12] 1) Flakes: Chitosan flakes are mostly used for the research studies, since they are easier to manage than gelled materials. However, the major limiting parameter with flaked material is the size of chitosan particles due to diffusion restrictions. 2) Gel beads: Gel beads are mainly used for the preparation of catalyst particles.

Generating Fuel from Plastic: Recent Report Amit Agnihotri* Department of Chemical Engineering, ITM, Gwalior, Madhya Pradesh, India

Plastics have become a part of our daily lives rom packaging, to bags and soda bottles. They are not only unsafe but their increased accumulation can cause big effects on our environment. Plastic products are found almost everywhere clogging the waterways, oceans, forests, and other natural habitats that have animals who mistake harmful plastic products for food. They constitute nearly 10 % of daily discarded waste. The problem is that they break down very slowly, which means they are piling up in landfills and serving as the source material in artificial island creation in our seas.

kind, but until now have not been able to find a means for doing so that is both inexpensive and accessible. However, some success is being achieved in this area and scientists are looking forward to improvise it further. This new method involves mixing the plastics with an organometallic catalyst which is made by mixing readily available molecules that are doped with iridium metal. This reaction causes weakening of the bonds that hold the plastic together, allowing it to be easily torn apart.

Due to the use of chemical additives during plastic production, plastics have potentially harmful effects that could prove to be carcinogenic or promote endocrine disruption. Some of the additives are used as phthalate plasticizers and brominated flame retardants.

The broken pieces can later be used to create a diesel-like fuel which could be used to power vehicles and other motors.

In a recent research, a new way to degrade ordinary plastics and create fuel has been reported.

This new method of plastic degradation is not only easy to perform, but is quite inexpensive too.

A team of researchers from the Chinese Academy of Sciences and University of California have published in the journal Science Advances about this new finding.

However, there still remains a question if it is scalable or not. Also, as iridium is too expensive, it is not feasible to obtain it in sufficient quantities. The team is looking for other ways to make this method more practical and available for commercial use. In an effort to find alternatives for degrading plastic materials, we can hope to have a cleaner environment in future.

Scientists have been looking for new ways to degrade plastics, especially polyethylene which is the most common

The scientists also claim that burning this fuel is also cleaner than burning other combustible materials.
