During the synthesis of monomer NVP, the key techniques include the synthesis and purification of monomer. In the synthetic process of polymer PVP, the key technologies mainly involve polymerization technology and drying technology. Acetylene method and gamma-butyrolactone methodAcetylene process is the mainstream NVP production process at present, with high maturity. The method takes acetylene and formaldehyde as starting materials, and obtains NVP monomer through multi-step reaction.Firstly, the PVP monomer NVP is produced by the acetylene method through the synthesis of 1, 4-butanediol (BDO), and then through catalytic dehydrogenation to ring, ammonolysis and acetylene addition.Acetylene process has the advantages of mature technology, cheap and easy to obtain raw materials, and suitable for large-scale industrial production. However, the acetylene process is long, the investment of fixed assets is large, the operating conditions are strict, and the main raw\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-2084","post","type-post","status-publish","format-standard","hentry","category-problems"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/2084","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=2084"}],"version-history":[{"count":1,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/2084\/revisions"}],"predecessor-version":[{"id":2086,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/2084\/revisions\/2086"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=2084"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=2084"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=2084"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=2084"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
