Abstract

The invention provides a chloropropanol production device and a method for producing chloropropanol by using the device. According to the method, a tubular reactor or tower reactor in the prior art is replaced with a bubbling reactor, and an inner sleeve structure is added in a conventional bubble type reactor. When the device is used for producing chloropropanol, after mixed materials enter an inner sleeve, a bubbling effect is formed immediately, propylene and chlorine are fully dissolved in water in the process and fully mixed with chlorine water for reaction, propylene with a high value is effectively used, exhaust emission is reduced, the production yield is increased, and the exhaust treatment capacity and the treatment difficulty are reduced. Compared with chloropropanol production devices in the prior art, the process for producing chloropropanol by using the device is simple and convenient, at the same time, the device structure is simple, the reactor size is reduced remarkably, the equipment investment is little, the building project is reduced, and the whole device investment is small.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a chloropropanol production device and a method for producing chloropropanol using the same. Background technique [0002] Chloropropanol is an important chemical raw material, which is mainly used in the production of propylene oxide and chlorpromazine in industry. In the prior art, the production of chloropropanol is mainly realized by using tubular reactors or tower reactors, both of which have certain technical defects. Among them, in the process of producing chloropropanol by using a tubular reactor, in order to ensure sufficient reaction, it is necessary to set up a very long reaction pipeline, which will increase the investment in civil construction and equipment on the one hand, and on the other hand will lead to difficult control of process conditions and Difficult maintenance and other technical problems; in the process of producing chloropropanol with a towe...
