As the main raw material for the development of biomass fiber PTT, it can replace ethylene glycol and butanediol to produce polyol polyester. 1, 3-propylene glycol products were originally developed by the three major chemical industry giants Shell, Evonik and DuPont, and were mainly used to produce PTT polyester. However, these three companies use different methods to produce 1, 3-propylene glycol. Among them, Shell Company uses ethylene oxide carbonylation method (EO method), Degasse company uses acrolein hydrate hydrogenation method (AC method), DuPont company uses biological fermentation method. Among them, the acrolein synthesis method was proposed by Evonik Company in Germany, which was industrialized in 1995 and has been shut down. Acrolein process has high raw material cost, heavy pollution, complex separation and easy residual carbonyl compounds, which is not good for polymerization. Ethylene oxide method was proposed by Shell,\u2026<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"attr":[44],"class_list":["post-2038","post","type-post","status-publish","format-standard","hentry","category-problems"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/2038","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/comments?post=2038"}],"version-history":[{"count":2,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/2038\/revisions"}],"predecessor-version":[{"id":2041,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/2038\/revisions\/2041"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=2038"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=2038"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=2038"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=2038"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
