Nature
A colorless or yellowish liquid, paste, or solid. Soluble in hot water and alcohols, 1% of the aqueous solution pH value of 6~8. Decasix alkyl trimethyl ammonium chloride is a cationic surfactant, which can be heat resistant, light resistant, light resistant, resistant to strong acids and strong bases, and has good surface activity, stability and biodegradability.
Preparation Method
Under the catalysis of CuO/Cr2 03 system catalyst with silica gel as carrier, decasix alkyl dimethyl tertiary amine was synthesized from decasix alcohol and dimethylamine at a certain temperature and pressure. Decasix alkyl trimethyl ammonium chloride was prepared by using sodium hydroxide as catalyst and methyl chloride.
Introduction
It is a cationic quaternary ammonium salt. Soluble in water. It is irritating to eyes and skin.
Use
in petroleum, paper, food processing, textile and other industrial water treatment as a fungicide. Can be used for natural and synthetic fibers, plastics, paper and other industries of antistatic agents, leather softener, fiber softener, pigment finishing agent, asphalt and high temperature oil-in-water emulsion slurry emulsifier. Latex industry as anti-adhesion agents, organic synthesis of catalysts, metals and alloys of corrosion inhibitors. It can also be used as dispersant, coagulant aid, duckweed insecticide, etc. Good compatibility with cationic, nonionic and amphoteric surfactants.
Safety
It is irritating and corrosive to eyes. Rat oral LD50 250 mg/kg,300 mg/kg. Care was taken not to mix with the anionic surfactant.

| detection method | CN201210563535.0 discloses a detection method for sterilized residual cichloride in the production process of sodium hyaluronate. the steps are to prepare cichloride standard solution for linear regression equation; Prepare sample solution, use modified potassium bismuth iodide to color, and measure its absorbance value; The content of cichloride is calculated by linear regression equation. The method of making the linear regression equation is as follows: the prepared standard solution of 2 μg/ml, 4 μg/ml, 8 μg/ml, 10 μg/ml and 20 μg/ml, and the absorbance at 290nm was measured after color development with improved bismuth potassium iodide test solution. Using the method of the present invention to detect the content of cichlorium, can make up for the current cichlorium as a disinfectant or reaction reagent can not monitor its content and residual amount of the shortcomings, and the method of the present invention to detect the cichlorium content, greatly shorten the detection time, reduce the detection cost, especially suitable for laboratory detection of cichlorium content. | |
