Abstract

The invention relates to the technical field of preparation devices of chemical raw materials and discloses a preparation process for tin tetrachloride. A device comprises a reaction chamber, a tin storage chamber and a support frame, wherein the tin storage chamber penetrates the middle of the support frame and extends into the support frame and is fixedly connected with the support frame, the bottom of the tin storage chamber is fixedly connected with a connecting plate, a cavity is formed in the connecting plate, the left side in the cavity is fixedly connected with a fixed block, and the right side of the fixed block is fixedly connected with a spring. According to the preparation process for tin tetrachloride, by arranging the connecting plate, the cavity, the fixed block, a spring, aconnecting rod, a handle, a movable block, a disc, motors and flame guns, the problem that a reaction needs to be stopped during charging in a production process of tin tetrachloride production equipment is solved, and production efficiency is increased; an operator is not needed to hold one flame gun to heat a reaction tank, operation is convenient, and heating is uniform.

Description

technical field [0001] The invention relates to the technical field of preparation devices for chemical raw materials, in particular to a process for preparing tin tetrachloride. Background technique [0002] Anhydrous tin tetrachloride is a colorless liquid that flows easily, and its gas molecules are in a regular tetrahedral configuration. Bond length Sn—Cl228pm. Melting point -33°C, boiling point 114.1°C. The density is 2.226g / cm³. Miscible with carbon tetrachloride, ethanol, benzene, easily soluble in water, soluble in gasoline, carbon disulfide, turpentine and most other organic solvents. Slowly add water to generate SnO2 colloid and hexachlorostannoic acid. In case of humid air, it will be hydrolyzed to generate stannic acid and hydrogen chloride, and white smoke will be produced, which is corrosive. With the calculated amount of water, tin tetrachloride pentahydrate is formed. Used as a mordant and a chlorination catalyst in organic synthesis, and for tin platin...
