环氧丙烷(PO)主要用于生产聚醚多元醇、丙二醇和各类非离子表面活性剂等,其中聚醚多元醇是生产聚氨酯泡沫、保温材料、弹性体、胶粘剂和涂料等的重要原料,各类非离子型表面活性剂在石油、化工、农药、纺织、日化等行业得到广泛应用。同时,环氧丙烷也是重要的基础化工原料。目前,全球PO的应用主要以生产聚醚多元醇为主,约占总产量的65%;其次是丙二醇,占18%;其它为用于纺织助剂、油田助剂、农药助剂等领域的非离子表面活性剂及精细化工产品等[1,2]。
Propylene oxide (PO) is mainly used in the production of polyether polyols, propylene glycol and various non-ionic surfactants. Among them, polyether polyol is an important raw material for producing polyurethane foam, heat preservation materials, elastomers, adhesives and coatings, Various non-ionic surfactants in petroleum, chemical, pesticide, textile, cosmetic and other industries are widely used. At the same time, propylene oxide is also an important basic chemical raw material. At present, the application of global PO is mainly based on the production of polyether polyols, accounting for about 65% of the total output; followed by propylene glycol, accounting for 18%; others are used in textile auxiliaries, oilfield auxiliaries, pesticide additives and other fields Non-ionic surfactants and fine chemical products [1,2].
