Ethylene chloro hydrin

The Carbide and Carbon Co began large scale manuf of EtnO thru ethylene chloro-hydrin in 1925 and by the direct oxidation of ethylene in 1937. Dow entered the field in 1939 Si 1941 Jefferson and Wyandotte in 1941 and Mathieson Chem Corp in 1951. These four Co s used the chlorohydrin method. US consumption, which was in 1939 108 million pounds, increased in 1949 to 354 million Several laboratory methods of prepn are described in Ref 17, pp 75—7. In one of them hydroxide is added gradually to a soln of 2-chloroethyI acetate heated to a temp betwn 40 150°C. An excess of unreacted base is avoided. The reaction proceeds as follows ... 

According to descriptions published by the Thiokol Chemical Corporation [9] and Gobel [10] liquid thiokol is obtained in the following way ethylene chloro-hydrin is condensed into dichlorodiethylformal (I) which is then treated with sodium polysulphide to form the polymer (II) ...

It is also useful when monoacyl derivatives are required but several hydroxyl groups or various carboxyl groups might otherwise react. For instance, monoacyl derivatives of ethylene glycol can be obtained conveniently from chloro-hydrin in accord with the Scheme ...
