ammonium,dodecyltrimethyl-,bromide - Preparation method
Open Data Verified Data
Put the aqueous solution of trimethylamine into a vaporization kettle, heat it to boiling, and the generated trimethylamine gas is dried and absorbed with acetone. In the absorption tower, a trimethylamine acetone solution is generated and enters the quaternization kettle. Then, under stirring, dodecane bromide is added dropwise, maintaining a constant temperature during the dropwise process. After the dropwise addition, it is stirred for 1 hour with insulation. Cool and crystallize to obtain the crude product. Wash the product with acetone and dry it to obtain the final product.

ammonium,dodecyltrimethyl-,bromide - safety
Open Data Verified Data
It poses great harm to water, even if a small amount of product seeps into the ground, it can pose a danger to drinking water. Therefore, waste should not be directly discharged into the surrounding environment. The actual toxicity to organisms is 5.2mg/kg for intravenous injection in mice and 6800mg/kg for intravenous injection in rats. Store in a cool and dry environment to prevent exposure to sunlight and rain. During transportation and storage, it should be handled with care, protected from collision and freezing to avoid damage or leakage.
