Acid (acetic, glacial acetic) Aceticacid (Aceticacid, glacial) Content: 99% CAS: 69-19-7 Molecular formula: C2H4O2 Molecular weight: 60.06 Properties: Transparent colorless liquid above 16\u2103. Has a pungent special smell. If diluted with water, it will have a sour taste. Boiling point 118.1\u2103. Relative concentration 1.049. Melting point 16.7\u2103, below 16\u2103 for leafy crystal. When mixed with a small amount of water, it heats up, the capacity decreases, and the relative density increases. Concentration 77%~79% Relative density *. It reacts with most metal oxides and organic bases to form acetate. Soluble phosphorus sulfur. Still can dissolve fat oil, pigment, protein, resin, etc., dissolution ability is very strong. Stable to oxidant and reducing agent. Easy to catch fire. Contact with nitrogen produces white smoke. Its vapor irritates respiratory organs and burns when in direct contact with the skin. It has bactericidal effect. The vapor can pass through the polyethylene film. It is miscible\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":[88],"attr":[],"class_list":["post-762","post","type-post","status-publish","format-standard","hentry","category-problems","tag-glacial-acetic-acid-food-grade"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/762","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=762"}],"version-history":[{"count":4,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/762\/revisions"}],"predecessor-version":[{"id":998,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/762\/revisions\/998"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=762"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=762"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=762"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=762"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
