| Application | octanoyl chloride is an important class of organic chemical raw materials, mainly used as paper pulp sizing agent alkyl ketene dimer (AKD) synthesis, it is also widely used in the synthesis of medical materials, dyes, surfactants, etc. |
| preparation | octanoyl chloride is an important class of organic chemical raw materials, which is generated by the chlorination of straight chain carboxylic acid, at present, the production process of preparing hard Ester acid chloride is mainly based on gas phase phosgenation method and liquid phase phosgenation method. However, the process of phosgene method is complicated and the operation is troublesome, super toxicity makes it a great application in practical application. |
| Use | used as an intermediate in the synthesis of Cine dyes used as a color film coupler (e. G. 535,577,169,133, etc.) of the intermediates. Also used for the production of amide anhydride and so on. It is used as a raw material for the esterification of alcohols and the synthesis of other organic compounds. |
| production method | stearic acid was mixed with dimethylformamide, and a catalyst was added to react with phosgene. The hydrogen chloride and the excess phosgene formed in the reaction were then driven off with nitrogen and distilled under reduced pressure to obtain the final product. Raw material consumption quota: stearic acid 970kg/t, phosgene (98%)420kg/t, dimethylformamide (98%)10kg/t, liquid alkali (30%)400kg/t. |
