The specific production process should bePVP production process:Acetylene process is the mainstream PVP production process.The production process of PVP can be divided into acetylene method and gamma-butyrolactone method.In the acetylene process, acetylene and \u03b1-pyrrolidone are used to produce NVP (n-vinylpyrrolidone), and then polymerize to produce PVP.The \u03b3-butyrolactone method is to produce hydroxyethyl pyrrolidone by \u03b3-butyrolactone method and ethanolamine, and then dehydrate to produce PVP.Acetylene process is the mainstream large-scale industrial production process at present. It has certain advantages over gamma-butyrolactone method in product quality, production yield (mature process), and economy (cheap and easy to obtain raw materials). Gamma-butyrolactone method is more suitable for the production of small and medium-sized processes. In acetylene process, 1, 4-butanediol (BDO) is synthesized from acetylene and formaldehyde, and after catalytic dehydrogenation, ya-butanolactone, cyclogenesis, ammonolysis, acetylene addition and other reactions, NVP is obtained.The monomer vinylpyrrolidone (NVP) was prepared by bulk polymerization and solution polymerization.In the process\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":[111],"class_list":["post-1439","post","type-post","status-publish","format-standard","hentry","category-problems"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1439","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=1439"}],"version-history":[{"count":1,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1439\/revisions"}],"predecessor-version":[{"id":1441,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1439\/revisions\/1441"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=1439"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=1439"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=1439"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=1439"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
