Brief introduction of benzoyl chloride:
Also known as chlorobenzoyl benzoyl chloride, chemical formula C7H5ClO [1], molecular weight 140.57
CAS Login No. 98-88-4 EINECS Login No. 202-710-8
A compound formed by replacing the hydroxyl group in benzoic acid with chlorine atom. Vapor is tear inducing. When encountering water or ethanol, it gradually decomposes to form formic acid.
Property description
Colorless and transparent, it will smoke when exposed to the air. It has a special pungent odor. The vapor irritates the mucous membrane of the eye and induces tears. The freezing point is - 1.0 ℃, and the refractive index is 1.5537. It decomposes gradually when encountering water, ammonia or ethanol.
Production method
The raw material of toluene method reacts with light, hydrolyzes in acid medium to generate formyl chloride, and emits hydrogen chloride gas (HCl gas emitted should be absorbed by water during production). 2. Formic acid reacts with gas. Put formic acid into the photochemical pot, heat and melt it, and inject gas at 140-150 ℃. The reaction tail gas contains unreacted gas, which is vented after alkali treatment. The temperature at the end point of the reaction is - 2-3 ℃. The finished product is obtained by vacuum distillation after purging operation. Industrial products are transparent liquid with micro color. Purity ≥ 98%.
purpose
Benzoyl chloride is an important benzoylation and benzylation reagent for organic synthesis of benzoyl chloride. Most benzoyl chloride is used to produce benzoyl peroxide. Silicone fluorine rubber cross-linking agent, oil refining, powder bleaching, fiber bleaching, etc. There were more than 20 benzoyl chloride manufacturers in China, and some benzoic acid manufacturers also produced benzoyl chloride, with a production capacity of 10000 tons. In addition, benzoic acid can also react with benzoyl chloride to produce benzoic anhydride, which is mainly used as an acylating agent, as a component of bleaching agent and flux, and also can be used to prepare benzoyl peroxide.
