Abstract
Chloromethyl methyl ether is produced by feeding approximately equivalent proportions of methyl alcohol and formaldehyde into a reaction zone maintained at a temperature between 0 DEG and 60 DEG C., while at the same time feeding hydrogen chloride into the zone in sufficient quantity to saturate the mixture; the reaction mixture is withdrawn and the layer of chloromethyl methyl ether is removed, the aqueous layer left is distilled to remove vapours of chloromethyl methyl ether, lower boiling components and some water which are mixed with the starting materials and recycled. The formaldehyde is preferably employed in the form of an aqueous solution containing from 27 to 40 per cent by weight of formaldehyde but solid forms of formaldehyde, e.g. paraformaldehyde, meta-formaldehyde, trioxymethylene, polyoxymethylene or a -trioxymethylene may also be used. The reaction may be carried out at atmosphoric pressure or at a pressure up to 20 lbs. p.s.i.g. Chloromethyl methyl ether of about 95 per cent purity is obtained and this can, if desired, be further purified, e.g. by distillation.
