Embodiment Construction

[0011] Specific embodiments of the present invention are given below to further illustrate the present invention.

[0012] A kind of production technique of tin tetrachloride of the present embodiment, change the gaseous-solid reaction in the former tin tetrachloride production process to be gaseous-liquid reaction, specifically comprise following technological process:

[0013] 1. Directly add tin ingots to the tin port of the tin tetrachloride reaction kettle for continuous tin feeding and continuous production, heat to melt the tin ingots into liquid tin, or directly add molten liquid tin to the tin tetrachloride reaction kettle;

[0014] 2. Continuously feed chlorine gas into the tin tetrachloride reactor. The chlorine outlet of the tin tetrachloride reactor is below the liquid tin level. Chlorine reacts with the melted liquid tin to generate gaseous tin tetrachloride. The tin reaction is an exothermic reaction, and no reheating is required during the reaction;

Abstract

The invention relates to a production process of tin tetrachloride, belonging to the technical field of tin tetrachloride production processes. The process comprises the following steps: 1, directly adding a tin ingot to the tin feeding port of a tin tetrachloride reaction kettle, and heating so as to melt the tin ingot into liquid tin; 2, continuously introducing nitrogen into the tin tetrachloride reaction kettle, and reacting chloride with the melted liquid tin so as to generate gaseous tin tetrachloride, wherein the nitrogen introducing port of the tin tetrachloride reaction kettle is below the liquid level of the liquid tin; 3, continuously adding the tin ingot from the tin feeding port according to reaction conditions, continuously melting the tin by utilizing the heat released in the process of reacting the chloride with the melted liquid tin, and controlling the reaction temperature at 200-300 DEG C through controlling a chloride feeding speed; and 4, introducing the gaseous tin tetrachloride generated in the tin tetrachloride reaction kettle into a condenser and recovering tin tetrachloride liquid. The process has the advantages of simple process flow, complete reaction and less possibility of chloride pollution; and the prepared tin tetrachloride has the advantages of high purity and high yield.

Description

technical field [0001] The invention relates to a production process of tin tetrachloride, belonging to the technical field of tin tetrachloride production process. Background technique [0002] At present, the existing tin tetrachloride production process is as follows: tin is melted to make round tin ingots, cut into tin wires, and about 1 ton of tin wires are put into a tin tetrachloride reactor with a volume of about 2400 liters. , Pass into chlorine gas, chlorine gas reacts with solid tin (silk) to generate liquid tin tetrachloride and discharges from the outlet. According to the reaction situation, add tin wire intermittently through the tin filling port. The reaction process is an exothermic reaction, and the reaction temperature is controlled between 100 and 130°C by controlling the rate of chlorine addition. Disadvantages: It is necessary to frequently open the mouth to replenish tin wire, which is easy to leak chlorine gas and cause environmental pollution. The ...
