腈 Stroke Order

腈 [jīng] 1. A class of organic compounds characterized by a special odor, which decomposes in the presence of acids or bases. 一类有机化合物，有特殊的气味，遇酸或碱分解。 (e.g., acrylonitrile) 2. Refers to a class of compounds characterized by the trivalent nitrogen group N≡ (English: nitrile), which can be derived from oxy-acids. The method involves completely removing the water component from the ammonium salt of the oxy-acid; usually refers to compounds characterized by the cyano group (e.g., acetonitrile, benzonitrile), which can be obtained from carboxylic acids or their amides, producing acids upon complete hydrolysis. 指以三价氮基N≡为特征的一类化合物 (英文：nitrile)，并可从含氧酸得到，其法是从含氧酸的铵盐中完全除去水的成分; 通常指以氰基为特征的化合物（如乙腈，苯腈），可从羧酸或它的酰胺得到，完全水解时产生酸。
