Abstract

The invention relates to an environmental-friendly catalyst used for synthesizing sulfur dichloride and a preparing method thereof. According to the preparing method, an excessive wet soaking method is adopted to prepare supported catalysts of various kinds, catalysts of different kinds are used to conduct a test of synthesizing sulfur dichloride, disulfur dichloride and excessive chlorine are introduced from the lower end of a tubular reactor, and standing time of reaction raw materials in the reactor is increased so that the amount of chlorine is further reduced. The environmentally friendly catalyst used for synthesizing sulfur dichloride and the preparing method thereof have the positive effects that a novel molecular sieve supported catalyst is provided to be used for synthesizing sulfur dichloride, and has the advantages of being simple in manufacturing technological operation, stable, continuously efficient, environmentally friendly, sanitary, and low in pollution.

Description

technical field

[0001] The invention relates to an environment-friendly catalyst for synthesizing sulfur dichloride, and also provides a preparation method of the catalyst, which belongs to the technical field of inorganic chemical production. Background technique

[0002] Sulfur dichloride is an important inorganic chemical product, which is widely used in organic synthesis, synthetic raw materials for pesticide intermediates, chlorides for the manufacture of acid anhydrides or organic acids, additives for high-pressure lubricants and cutting oils, and treatment of vegetable oils (such as corn oil, Soybean oil) processing agent, etc. It can also be used as a disinfectant and fungicide. CN91104832 discloses a synthesis method of sulfur dichloride, which uses sulfur and chlorine to synthesize disulfide dichloride at 30-80°C, and then adds catalyst FeCl3 (or Fe powder, FeCl2, AlCl3) to the reaction kettle, Control the reaction temperature at 30-80°C and pass chlorine gas int...
