Abstract
The synthesis method of chloroethanol by using ethylene oxide and hydrogen chloride as raw materials was introduced.Single variable control experiments were conducted,and the process conditions fora mass fraction of approximately 85％chloroethanol were obtained as follows:The mole ratio of ethylene oxide and hydrogen chloride was 1:1.05,the synthesis reaction temperature was 30 ℃,the neutralization reaction time was 40 min(for 185 kg/h of ethylene oxide flow rate),and the neutralization reaction temperature was 25 ℃.
