The reaction mixture was allowed to warm to room temperature and was then warmed to 40° for 30 min. and distilled using a 30 cm spiral coil columm. The main fraction (45 g, b.pt. 92°-97°) was redistilled to give dichloromethyl methylether (21.25 g, b.pt. 85°-85.5°) Patent; Burroughs Wellcome Co.; US4801593; (1989); (A1) English View in Reaxys

Yield

Conditions & References 7 : EXAMPLE 7 EXAMPLE 7 3.61 g of methyl formate and triphenylphosphine oxide bound on a resin, prepared by chlorination of 5.4 g of triphenylphosphine supported on polystyrene beads (3 mmol P/g) in 26.5 g of o-dichlorobenzene, are introduced into a reactor similar to that of Example 1 and the reaction mixture is then heated to 68° C. 7.5 g of phosgene are next introduced gradually over 2 hours while the temperature is maintained between 68° and 80° C. and heating is continued at this temperature for 9 hours. The degree of conversion of methyl formate to methyl 1,1-dichloromethyl ether, determined by GC, is 27percent.
