3-Dimethylaminopropylamine CAS: 109-55-7
Diamine is an important class of chemical substances that are widely used as raw materials, intermediates or products. For example, diamine is an important structural unit in the synthesis of polyamide and other condensation polymerization reactions. N,N-dimethyl-1Chemicalbook,3-diaminopropane (DMAPA) is an important intermediate, used for example in the industrial preparation of lubricants. In addition, DMAPA is used as a raw material for the preparation of coagulants and itself should have Anti-corrosion properties.
It is colorless transparent liquid. Soluble in water and organic solvents. Widely used in the manufacture of cosmetic raw materials, such as palmitamide dimethylpropylamine, cocamidopropyl betaine, mink oil amidopropylamine, etc.
Using dimethylaminopropionitrile [1738-25-6] as raw material, hydrogenation and methanol are added in the presence of Ni-Al catalyst, and then filtered and distilled to obtain the finished product of 3-dimethylaminopropylamine. The purity of the obtained product can reach more than 99%, and each ton of product consumes 1150kg of dimethylaminopropionitrile. -

N,N-Dimethylformamide CAS 68-12-2
Dimethylformamide is a colorless and transparent liquid. It is not only a widely used chemical raw material, but also an excellent solvent with a wide range of uses. Dimethylformamide is an important raw material for pharmaceutical, petrochemical, leather and other industries。
Dimethylformamide is referred to as DMF. It is a compound in which the hydroxyl group of formic acid is replaced by a dimethylamino group, with the molecular formula HCON(CH3)2. It is a colorless and transparent high-boiling point liquid with a light amine smell and a relative density of 0.9445 (25℃). Melting point -61℃. Boiling point 152.8℃. Flash point 57.78℃. Vapor density 2.51. Vapor pressure 0.49kpa (3.7mmHg25℃). Autoignition point is 445℃. The explosion limit of steam and air mixture is 2.2~15.2%. Exposure to open flames and high heat may cause combustion and explosion. It can react violently with concentrated sulfuric acid and fuming nitric acid and even explode. It is miscible with water and most organic solvents Chemicalbook. It is a common solvent for chemical reactions. Pure dimethylformamide has no odor, but industrial grade or deteriorated dimethylformamide has a fishy smell because it contains dimethylamine impurities. The name comes from the fact that it is a dimethyl substitute of formamide (amide of formic acid), and both methyl groups are located on the N (nitrogen) atom. Dimethylformamide is a polar (hydrophilic) aprotic solvent with a high boiling point, which can promote the SN2 reaction mechanism. Dimethylformamide is made from formic acid and dimethylamine. Dimethylformamide is unstable (especially at high temperatures) in the presence of strong bases such as sodium hydroxide or strong acids such as hydrochloric acid or sulfuric acid, and hydrolyzes to formic acid and dimethylamine.
It is very stable in the air and when heated to boiling. When the temperature is higher than 350°C, it loses water and generates carbon monoxide and dimethylamine. N,N-dimethylformamide is a very good aprotic polar solvent that can dissolve most organic and inorganic substances and is miscible with water, alcohols, ethers, aldehydes, ketones, esters, halogenated hydrocarbons and aromatic hydrocarbons. . The positively charged end of the N,N-dimethylformamide molecule is surrounded by methyl groups, forming a spatial Chemicalbook barrier that prevents negative ions from approaching and only associates positive ions. Bare anions are much more active than solvated anions. Many ionic reactions are easier to carry out in N,N-dimethylformamide than in general protic solvents. For example, carboxylates and halogenated hydrocarbons react in N,N-dimethylformamide at room temperature. , can generate esters with high yields, and is particularly suitable for the synthesis of sterically hindered esters.
