Abstract

The invention relates to a cracking reaction kettle, comprising a big reaction kettle barrel body and a small reaction kettle barrel body, wherein the diameter of the big reaction kettle barrel body is larger than that of the small reaction kettle barrel body, and the lower part of the big reaction kettle barrel body is connected with the small reaction kettle barrel body by means of an ellipticalhead; a transmission device is arranged at the upper part of the big reaction kettle barrel body; a transmission shaft of the transmission device extends into the big reaction kettle barrel body andthe small reaction kettle barrel body; a first stirring device is arranged on the transmission shaft in the big reaction kettle barrel body and comprises a U-shaped stirring rod; the vertical part ofthe U-shaped stirring rod is jointed with the inner of the big reaction kettle barrel body; arc-shaped parts of the left side and the right side of the U-shaped stirring rod are jointed with the innerside of the elliptical head. The cracking reaction kettle especially solves the problems of wall hanging of materials, temperature control, discharge clogging and the like which are caused in a process of producing sebacic acid by using castor oil and alkali.

Description

technical field [0001] The invention relates to a cracking reaction kettle, which is mainly used in chemical industry, dyestuff and pharmaceutical industries. Background technique [0002] Reactors are widely used in chemical reactions, especially polymerization reactions, and are often used in chemical, dye, and pharmaceutical industries. They are an important reaction equipment. Castor oil is a commercial oil mainly containing hydroxy acids. Castor oil is a brownish-yellow viscous vegetable oil. It has the characteristics of high viscosity, high polarity, strong hygroscopicity, and easy emulsification. It is also prone to intramolecular dehydration and oxidation. . Using castor oil and alkali to produce sebacic acid, the material in the reactor is very viscous and easily sticks to the wall of the kettle; the reaction temperature of the upper kettle body is 280 degrees, and the reaction temperature of the lower kettle body is 320 degrees. The temperature of the conventiona...
