|Section2= |Section3= }} Butyryl chloride (also known as n-Butyryl chloride, butanoyl chloride, or C-4 Acyl halide) is an organic compound with the chemical formula C4H7ClO. Butyryl chloride is liquid at room temperature, has a colorless to light yellowish appearance and has an extremely strong pungent odor. Butyryl chloride is soluble in almost all aprotic organic solvents, but it decomposes violently by heating and spontaneously decomposes when exposed to moist air or water to form pure hydrochloric acid gas. It also reacts violently when mixed with strong oxidants, metals (especially iron), alkali metals, alkali earth metals, bases and wide range of organic substances such as amines, dimethyl sulfoxide, and alcohols. These reactions tend to result in explosions and fire; hence extreme caution must be taken when mixing with other substances. Butyryl Chloride belongs in the group of acyl halides which are involved in acylation process that introduce an acyl group (RCO-) into compounds. ==Reactions== Derivatives of butyryl chloride are used in manufacturing pesticides, pharmaceuticals, perfume fixative, polymerization catalyst, and dyestuffs. Butyryl chloride is also commonly used as an intermediate for organic synthesis for the preparation of pharmaceuticals, agrochemicals, dyes, esters, and peroxide compounds.〔http://chemicalland21.com/specialtychem/perchem/N-BUTYRYL%20CHLORIDE.htm〕 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「Butyryl chloride」の詳細全文を読む スポンサード リンク
