Background and overview of Aliquat 336 CAS 5137-55-3
Methyl trioctyl ammonium chloride, also called trioctyl methyl ammonium chloride (CAS No. 5137-55-3), is a halogenated quaternary ammonium salt. Quaternary ammonium salts are a class of cationic surfactants. Among them, the halogenated quaternary ammonium salt (R1R2R3R4N+X-) series of compounds are widely used in daily chemical industry, textile, printing and dyeing, mining, asphalt, construction, plastic processing, petroleum exploration, petrochemical industry It played an important role in various fields.

Preparation of Aliquat 336 CAS 5137-55-3
Weigh 1000g of trioctylamine into a beaker, add concentrated hydrochloric acid (the total amount of HCl added is about 103g), magnetically stir, and after the neutralization reaction is completed, use a constant temperature water bath to evaporate about 80% of the water, and then vacuum dry to obtain the product three Octyl ammonium chloride: Weigh 1000g trioctyl ammonium chloride and 235g dimethyl carbonate respectively, and add them to a 10L reaction kettle in turn. After purging with nitrogen to remove the air in the kettle, the reaction is carried out in an airtight manner. The reaction temperature is 170°C. After the reaction temperature reached 170° C., the stirring was started, and the reaction time was 8 hours; after the reaction, about 1026 g of methyl trioctyl ammonium chloride was prepared.
