Preparation of sodium acetate trihydrate
Preparation of raw materials
To make sodium acetate trihydrate, first prepare acetic acid (CH 🥰 COOH) and soda ash (Na 🥰 CO 🥰). The acetic acid needs to be selected with high purity, and the less impurities are conducive to the purity of the reaction. Soda ash should also be of high quality to ensure the smooth progress of the reaction.

Reaction process
In a clean reactor, inject acetic acid and soda ash in an appropriate proportion. Stir slowly to make full contact between the two. This reaction is a neutralization reaction, and heat will be released during the process. Pay attention to temperature changes. The chemical reaction equation is: 2CH 🥰 COOH + Na 🥰 CO = 2CH 🥰 COONa + H 🥰 O + CO 🥰 ↑. Carbon dioxide gas escapes during the reaction, and the reaction environment should be well ventilated.

Crystallization operation
After the reaction is completed, a sodium acetate solution is obtained. The solution is heated and concentrated until a crystalline membrane appears. Then, stop heating and cool naturally. During the cooling process, sodium acetate trihydrate will crystallize and precipitate. It can be stirred properly to make the crystallization uniform.

Separation and drying
When the crystallization is complete, separate the sodium acetate trihydrate crystal from the mother liquor with a filter device. A little mother liquor will remain on the surface of the crystal, and an appropriate amount of ethanol needs to be rinsed to remove impurities. After that, the crystal is placed in a dryer and dried at low temperature to ensure moisture removal to obtain a pure sodium acetate trihydrate product.

Throughout the preparation process, it is necessary to strictly control the reaction conditions and operating specifications to ensure product quality and yield.
