Acyl chloride - Wikipedia
In organic chemistry, an acyl chloride (or acid chloride) is an organic compound with the functional group −C (=O)Cl. Their formula is usually written R−COCl, where R is a side chain. They are reactive derivatives of carboxylic acids (R−C (=O)OH). A specific example of an acyl chloride is acetyl chloride, CH3COCl.

Acid chlorides react with ammonia, 1o amines and 2o amines to form amides. Acyl chlorides (also known as acid chlorides) are one of a number of types of compounds known as "acid derivatives". This is ethanoic acid: If you remove the -OH group and replace it by a …
酰氯_化工百科 - ChemBK
酰氯(Acid chloride)是一类具有酰基(碳酰基)和氯原子的化合物。 酰氯呈现出刺激性的刺鼻气味,非常易于挥发。 它可以与水反应生成相应的酸和盐。 酰氯可以作为强酸性试剂,与碱反应生成盐和酰基碱。 酰氯可以用于酰基化反应,将酰基引入其他分子中。 酰氯可以用作制备酰胺、酯、酮和醚等化合物的中间体。 酰氯也可以用于高分子化合物的合成,如聚酰胺和聚酯等。 酰氯的制备通常涉及酸和氯化剂的反应。 常见的制备方法包括: 在碳酸盐和酰基氯化铝的存在下, …
Chloride - Wikipedia
In terms of its acid–base properties, chloride is a weak base as indicated by the negative value of the pK a of hydrochloric acid. Chloride can be protonated by strong acids, such as sulfuric acid: NaCl + H 2 SO 4 → NaHSO 4 + HCl. Ionic chloride salts …
Are acid chlorides really acidic? - Chemistry Stack Exchange
An acid chloride is a covalent molecule. It has no pH. If you put a pH electrode into a reactive acid chloride you will dehydrate and acylate its hydrated glass surface ($\ce{#Si-OH}$) and damage its future response when properly used. pH electrodes are stored sitting in buffer or saline solution.

an introduction to acyl chlorides (acid chlorides) - chemguide
Acyl chlorides (also known as acid chlorides) are one example of an acid derivative. In this case, the -OH group has been replaced by a chlorine atom. For UK A level purposes, the "R" group is normally restricted to an alkyl group. It could, however, equally well be a …
