Polyvinylpyrrolidone (PVP) is extremely soluble and can be dissolved in a variety of solvents. Specifically, PVP is soluble in water, chlorine-containing solvents, ethanol, amines, nitroalkanes, and low molecular fat acids. In addition, it has a good compatibility with most inorganic salts and a variety of resins. However, PVP is insoluble in a few solvents such as acetone and ether. This extensive solubility and compatibility gives PVP a unique advantage in a variety of applications. 12 Water solubility: PVP is highly soluble in water, which is one of its most important solubility properties.Organic solvent solubility: In addition to water, PVP can also be dissolved in halogenated hydrocarbon solvents, alcohols, amines, nitroalkanes and low molecular fatty acids and other organic solvents.Insoluble: In contrast, PVP is insoluble in a few solvents such as acetone, ether, turpentine, aliphatic hydrocarbons and alicyclic hydrocarbons.These physical and chemical properties make PVYrrolidone widely used in many fields such\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-1999","post","type-post","status-publish","format-standard","hentry","category-problems"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1999","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=1999"}],"version-history":[{"count":3,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1999\/revisions"}],"predecessor-version":[{"id":2003,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/1999\/revisions\/2003"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=1999"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=1999"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=1999"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=1999"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
