Water proof agent CR - Preparation method
Open Data Verified Data
1. Add 220 parts of 30% hydrochloric acid to the acid resistant tank, then add 80 parts of water and stir thoroughly. Add 100 parts of chromium trioxide at room temperature and stir until completely dissolved. To be used.
2. Add 250 parts of isopropanol and 25 parts of 30% hydrochloric acid to the reactor, and slowly add the above solution when heating to 60-65 ℃. After adding, heat up to 70 ℃ and reflux for about 1 hour. Add 175 parts of stearic acid and reflux for a few more hours. Measure the endpoint (dilute a certain amount of sample with 500 times water, without the presence of white stearic acid as the endpoint). After reaching the endpoint, cool to 30 ℃, add 50 parts of isopropanol, and stir well to obtain the finished product.

Water proof agent CR - Introduction
Stearoyl chromium chloride is an organic compound with the chemical formula C21H41ClCrO2. It is a colorless to light yellow liquid with a pungent odor and corrosive properties.
chromium stearoyl chloride is mainly used as a precursor for catalysts and surfactants. In the field of organic synthesis, it is often used in the preparation process of polymers and coatings to enhance the water resistance and heat resistance of substances. In addition, it can also be used in the production process of dyes, resins, plastics, etc.
A common method for preparing stearoyl chromium chloride is to react stearic acid with chromium chloride in an appropriate solvent. In order to ensure the efficiency and safety of the reaction, it is necessary to control the temperature and the dosing sequence of the reactants.
However, stearoyl chromium chloride is an irritating and corrosive substance that may cause irritation in contact with skin and eyes. Therefore, wear protective gloves, goggles, and protective clothing when using stearyl chromium chloride. At the same time, the storage and handling of the compound should follow safe operating procedures, away from fire and heat sources, and avoid contact with oxidants and acids. In the event of an accident, immediately flush the patient with plenty of water and seek help from the medical staff.
