Sulfur chlorinated isobutylene production equipment and method

Abstract

The invention provides sulfur chlorinated isobutylene production equipment, comprising an enamel gas liquid reaction kettle and a falling film absorption tower. According to the technical main points, the enamel gas liquid reaction kettle comprises an upper sealing head, a kettle body and a stirring shaft; a stirring blade is arranged on the stirring shaft; a jacket is arranged outside the kettle body; a cooling liquid inlet and a liquid outlet are arranged on the jacket; the upper sealing head is connected with the kettle body together; a feeding opening and an air exhaust opening are arranged at the upper part of the kettle body; the air exhaust opening is communicated with the falling film absorption tower; a discharging opening is arranged at the center of the bottom of the kettle body; an air inlet pipe is arranged at the bottom of the kettle body; and three to five air inlet pipes are uniformly and coaxially distributed on the rim of the discharging opening. The sulfur chlorinated isobutylene production equipment provided by the invention has the advantages that single sulfur chloride and isobutylene can be subjected to multipoint reaction, so that the reaction process tends to be stable, the reaction temperature is easy to control, side product amount can be reduced, the reaction time is shortened, the yield can be improved, and the production cost can be reduced; the isobutylene has sufficient reaction time, so that the raw materials can be prevented from being wasted; and the defects that the enamel has low toughness, is easy to break and the like can be overcome without arranging an individual air exhaust annular pipe, so that the occurrence of the safe accident can be avoided.

Description

technical field [0001] The invention relates to a gas-liquid reaction kettle, in particular to a gas-liquid reaction kettle with a porous bottom, which is mainly used for reaction equipment of sulfur chloride and isobutylene at normal temperature. Background technique [0002] Sulfurized isobutylene (T321) is a sulfur-containing additive single agent, which is widely used in the preparation of high-grade gear oil, anti-wear hydraulic oil, cutting oil, lubricating grease and the main extreme pressure anti-wear agent of industrial oil. Its production process in the world is mainly based on isobutylene, sulfur monochloride and alkali metal or alkaline earth metal sulfide as raw materials through addition reaction and sulfuration dechlorination reaction. [0003] The by-products hydrogen chloride and hydrogen sulfide are generated during the reaction. Among them, sulfur monochloride (also known as disulfur dichloride, sulfur monochloride) is light yellow oily liquid at normal t...
