丁腈 (Butyronitrile)是一种橡胶,由丙烯腈和丁二烯合成。代号NBR 腈 (jīng):有机化合物的一类,有特殊的气味,遇酸或碱分解。 分子式(Formula): C4H7N 分子量(Molecular Weight): 69.10 CAS No.: 109-74-0 外观(Appearance): 无色透明液体 含量(Purity): 98% 包装(Package): 150公斤/桶 用途(Useage) 是有机合成及医药中间体的关键原料 Butyronitrile or butanenitrile or propyl cyanide, is a nitrile with the formula C3H7CN. This colorless liquid is miscible with most polar organic solvents. It is mainly used as a precursor to the poultry drug amprolium. Butyronitrile is prepared industrially by the ammoxidation of n-butanol:
