|Section2= |Section3= |Section4= |Section5= }} Acetone cyanohydrin (ACH) is an organic compound used in the production of methyl methacrylate, the monomer of the transparent plastic polymethyl methacrylate (PMMA), also known as acrylic. It is extremely toxic. ==Preparation== The compound is generated as part of the acetone cyanohydrin route to methyl methacrylate. It is treated with sulfuric acid to give the sulfate ester of the methacrylamide, methanolysis of which gives ammonium bisulfate and MMA.〔.〕 In the laboratory, this compound may be prepared by reacting sodium cyanide with acetone, followed by acidification: :400px A simplified procedure involves the action of sodium or potassium cyanide on the sodium bisulfite adduct of acetone prepared ''in situ''. This gives a less pure product that is suitable for most syntheses. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「acetone cyanohydrin」の詳細全文を読む スポンサード リンク
