| Introduction | decahexyl dimethyl tertiary amine is an industrial fungicide. Industrial bactericide refers to the preparation used to kill or inhibit the growth of microorganisms in industry, and has many application fields. Quaternary ammonium salt bactericide is one of the most widely used industrial bactericides. However, the widely used quaternary ammonium salt bactericides generally have small molecular weight and have certain physiological toxicity and skin irritation, during use, migration and dissolution may be released into the surrounding environment, which may cause damage to organisms and the environment. |
| preparation | in a ml Four-necked bottle with mechanical stirring, add 24.1g of decamyl amine and ML of absolute ethanol, 20.9g 88% formic acid and 24.3g 37% formaldehyde are added at a controlled temperature below 20 ° C., the reaction system is sealed with a balloon, heated to reflux for 10 hours, and sampled at a reduced temperature. TLC is used to detect complete reaction. 30% liquid alkali was added to the reaction solution to neutralize to pH 10, and toluene was added for extraction. The toluene layers were combined, washed and desolved, and distilled under reduced pressure to obtain 16.8g of colorless transparent liquid with a yield of 62%, content ≥ 95.0%. |
| Application | used in the preparation of quaternary ammonium salt, betaine, tertiary amine oxide, etc. raw materials for the production of efficient whitening agent, pesticide emulsifier, plant growth stimulating hormone a-naphthalene acetic acid, surfactant, solvent, etc.; Polyvinyl chloride fiber and polyester dyeing carrier, heat carrier; Determination of the octane number and the ten six alkanes of diesel oil. |
