Title: Improvements in the manufacture and production of vinyl ethers
IPC: C07C43/16
Filed: 1936-09-11
Abstract: Vinyl ethers are manufactured by treating an alcohol with acetylene at elevated temperature in the liquid phase in the presence of a zinc or cadmium salt of an organic acid, e.g. of formic, acetic, butyric, a -methylvaleric, stearic, oleic, abietic or naphthenic acid, advantageously in admixture with ammonia or a tertiary heterocyclic base, e.g. pyridine or quinoline.  The process is applicable to compounds containing at least one free alcoholic hydroxy group, and particularly to compounds containing also a sensitive group, such as partially etherified or acetalized sugars, e.g. tetramethylglucose, b -diacetone-fructose, monoacetone-glucose or a mixture of b -diacetonefructose and diacetone-glucose such as is formed by the treatment of cane sugar with acetone and sulphuric acid, or the corresponding methylene, ethylidene and benzylidene acetals, also alcohols containing ester groups, such as hydroxy fatty acid esters and mono- or polyfatty acid esters of polyhydric alcohols, e.g. glycolic acid esters, glycol monoacetate or glycerol diacetate.  In examples: (1) diethylene glycol monoethyl ether is treated with a mixture of nitrogen and acetylene under 10-20 atmospheres pressure, at 180 DEG  C. in the presence of cadmium acetate, to produce diethylene glycol monoethyl monovinyl ether; (2) glycol monoacetate is similarly treated at 150-170 DEG  C. in the presence of zinc naphthenate or a -methylvalerate, yielding glycol monoacetate vinyl ether; (3) glycerol diacetate is similarly treated at 148-170 DEG  C. in the presence of zinc naphthenate, to yield glycerol monoacetate divinyl ether (formed as a result of the replacement of one acetic acid radicle by a vinyl group), and some glycerol diacetate monovinyl ether; (4) sugar is treated with sulphuric acid and paraldehyde, and the resulting mixture of the ethylidene acetals of glucose and fructose is treated at 153-168 DEG  C. with a mixture of acetylene and nitrogen under pressure, in the presence of quinoline and dehydrated zinc acetate.
