Description of 3-Dimethylaminopropylamine

Dimethylaminopropylamine (aka “DMAPA”) is a diamine used in the preparation of some surfactants, such as cocamidopropyl betaine which is an ingredient in many personal care products including soaps, shampoos, and cosmetics.
DMAPA is commonly produced commercially via the reaction between dimethylamine and acrylonitrile to produce dimethylaminopropionitrile. A subsequent hydrogenation step yields DMAPA.

What is 3-Dimethylaminopropylamine?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 3-Dimethylaminopropylamine which has developed particularly rapidly in recent years. Do you know about 3-Dimethylaminopropylamine?


The official answer: N, N-dimethyl-1,3-diamino propane is an organic compound with the molecular formula C₅H₁₄N₂.

What’s the application of 3-Dimethylaminopropylamine?

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

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
