3-Dimethylaminopropylamine CAS# 109-55-7

Diamines are an important class of chemicals widely used as raw materials, intermediates, or products, for example, diamines are important structural units in the synthesis of polyamides and other polycondensation reactions. In addition, DMAPA is used as a raw material for the preparation of coagulants and should itself have anticorrosive properties. Colorless transparent liquid. Soluble in water and organic solvents. Widely used in the manufacture of cosmetic raw materials, such as palmitate dimethyl propylamine, Cocamidopropyl betaine, sable amide propylamine, etc.N, N-dimethyl-1,3-propane diamine is an intermediate of fungicide fenitrothion. Used as an organic synthesis intermediate, used to make dyes, ion exchange tree ester, epoxy resin curing agent, oil and non-cyanide electroplating zinc additives, fiber and leather treatment agents, and fungicides. The Chemical book contains both primary and tertiary amine groups in the molecule, so it is used as an epoxy resin curing agent with both functions of curing agent and accelerator. It is mainly used for laminated products, casting products and adhesives, etc. The general dosage is 2-6 parts. Used in organic synthesis. Epoxy resin curing agent. Dimethylaminopropionitrile [1738-25-6] is used as raw material for hydrogenation and methanol in the presence of Ni-Al catalyst, and then filtered and distilled to produce the 3-dimethylaminopropylamine finished product. The purity of the obtained product can be more than 99%, and the consumption of dimethylaminopropionitrile is 1150 kg per ton of product. Chemical book after the crude product moved into the distillation kettle for reduced pressure distillation, first to remove the solvent, and then collect 73 ~ 75 ℃ / 9 × 103Pa fraction for the product. Reaction equation: (CH3)2NCH2CH2CN+2H2[catalyst] → (CH3)2NCH2CH2CH2CH2NH2
