storage method
store sealed in a cool, dry place. make sure the workspace has good ventilation. keep away from sources of fire. store away from oxidizing agents.
synthesis method
liquid-phase catalytic amination of dodecanol and dimethylamine at normal pressure and 180-120°c removes a molecule of water to obtain crude tertiary amine, which can be distilled under reduced pressure to obtain high-purity finished dodecyl tertiary amine. .
purpose
used as an important intermediate in the synthesis of vitamin e. used to prepare fiber detergents, fabric softeners, asphalt emulsifiers, dye oil additives, metal rust inhibitors, antistatic agents, etc.
