Synthesis method for stannic chloride

Abstract

The invention relates to the technical field of preparation equipment of stannic chloride and discloses a synthesis method for stannic chloride. The preparation equipment comprises support legs and areaction purifying tank; a reaction kettle main body is fixedly sleeved in the support legs; a connecting cylinder is fixedly connected with the top of the reaction kettle main body; a lateral box isfixedly arranged on the right side of the connecting cylinder. The reaction purifying tank, an activated carbon adsorption net and an acid-proof sucking pump are arranged in a synthesis device of stannic chloride; under the action of the acid-proof sucking pump, gas in the reaction kettle main body can be extracted through a right-angle pipe and then is guided into the reaction purifying tank through a connecting pipe, and unreacted chlorine can react with calcium hydroxide in the reaction purifying tank, so that the neutralization of chlorine can be realized; the activated carbon adsorption net is used for absorbing and purifying gas discharged from the reaction purifying tank, so as to avoid pollution to surrounding air.

Description

technical field [0001] The invention relates to the technical field of tin tetrachloride preparation equipment, in particular to a synthesis method of tin tetrachloride. Background technique [0002] Anhydrous tin tetrachloride is a colorless and easy flowing liquid, the gas molecule is a regular tetrahedral configuration, and tin tetrachloride is the main raw material for the preparation of organotin compounds, which are mainly used to make PVC products and as heat stabilizers. As the raw material of the agent, as the demand for PVC products and heat stabilizers gradually increases, the demand for organotin compounds and tin tetrachloride, the main raw material for making organotin compounds, gradually increases. [0003] At present, when chemical companies produce and prepare tin tetrachloride, they generally add tin blocks and cold water inside the reactor, then introduce chlorine gas into the reactor, and then heat the reactor to make the gap between the tin block and th...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a synthetic method of tin tetrachloride, which has the advantages of preventing the overflow of unreacted chlorine gas, and solves the problem that after the reaction kettle generates tin tetrachloride, the inside of the reaction kettle is still A small amount of chlorine gas will remain, and when the operator opens the reactor to add tin blocks for the next chemical reaction, the chlorine gas will overflow, which will not only pollute the surrounding environment, but also cause harm to the health of the operator question
