制造环氧乙烷
Ethylene oxide has been produced commercially by two basic routes: 环氧乙烷已经商业化生产，由两个基本路线 ：
1. 1。
From ethylene chlorohydrin. 从乙烯氯。
2. 2。
Direct oxidation process. 直接氧化过程。
The chlorohydrin process was first introduced during World War I in 氯过程在第-次世界大战期间首次推出
Germany by Badische Anilin-und Soda-Fabrik (BASF). 德国巴登苯胺和苏打Fabrik公司（BASF）。 The process 这个过程
involves the reaction of ethylene with hypochlorous acid followed by 其次涉及次氯酸与乙烯反应
dehydrochlorination of the chlorohydrin with lime to produce ethylene oxide 与石灰氯，氯化氢，生产环氧乙烷
and calcium chloride. 氯化钙。 Union Carbide Corp. was the first to commercialize 联合碳化物公司是第-个以商业化
this process in United States. 这在美国的过程。 The chlorohydrin process is not economically 氯的过程是不经济
competitive， and was quickly replaced by the direct oxidation process as the 竞争力，并很快被取代了直接氧化过程
dominant technology. 主导技术。 At present time， all the ethylene oxide production in 目前，所有的环氧乙烷生产
the world is achieved by the direct oxidation process. 世界是通过直接氧化过程。
The direct oxidation technology， as the name implies， utilizes the 直接氧化技术，顾名思义，利用
catalytic oxidation of ethylene with oxygen over a silver based catalyst to 超过银基催化剂催化氧化，与氧乙烯
yield ethylene oxide. 产量环氧乙烷。 The process can be divided into two categories 该工艺可分为两大类
depending on the source of the oxidizing agent. 撒于氧化剂的来源 。 The air-based process and 空基的过程和
the oxygen based process. 基于氧气的过程 。 In the first ， air or air enriched with oxygen is fed 在第-阶段，丰富的空气或空气与氧气送入
directly to the system. 直接系统。 In the second high purity oxygen stream (>98 mol%) 在第二个高纯度的氧气流（> 98 mol%的）
from an air separation unit is employed as the source of the oxidizing agent. 受聘为氧化剂的来源是从空气分离装置 。
