Uses and synthesis of Dimethylamine liquid

Dimethylamine liquid (dimethylamine), also known as dimethylamine, is an organic compound, is a colorless flammable gas or liquid, high concentration or compressed liquefaction with ammonia odor, low concentration has a fish oil stench, Dimethylamine CAS 124-40-3 is soluble in water, soluble in ethanol and ether, toxic.

Dimethylamine CAS 124-40-3 is a gas at room temperature. Has an odor similar to ammonia. Relative density 0.680(0℃). Melting point -96℃. Boiling point 7.4℃. Soluble in water, soluble in ethanol and ether. Easy to burn. Weakly alkaline, Dimethylamine Raw Materials and inorganic acids to generate easily soluble in water salts. Used as raw materials for making drugs, dyes, insecticides and rubber vulcanization accelerators.Dimethylamine liquid is produced by the action of ammonia and methanol at high temperature and high pressure and in the presence of catalyst.

Applications / Functions of Dimethylamine liquid

1. Dimethylamine CAS 124-40-3 is used as a raw material for the production of drugs, dyestuffs, pesticides, leather dehairing agents, rubber vulcanization accelerators, rocket propellants, etc.
2. Dimethylamine CAS 124-40-3 is an important intermediate of pesticides, it can be used to prepare fungicide Fomesafen, Fomesafen, Fomesafen, Fomesafen, Fomesafen, Fomesafen, Fomesafen, Fomesafen, Fenitrothion, Dimethoate, insecticide Aphidicarb, Insecticide Dinitrothion, Insecticide Mono, Fenitrothion, Fenitrothion and Herbicide Chlormidon, Isopropylenon, Cyclosazinone, Fluoroxuron and so on.
3. Dimethylamine Raw Materials is mainly used as raw materials for rubber vulcanization accelerator, leather dehairing agent, medicine (antimicrobial agent), pesticide (herbicide such as fumonisin, acetamiprid and mirex), textile industry solvent, dyestuffs, explosives, propellant, and organic intermediates such as dimethylhydrazine and N,N-dimethylformamide. Among them, Dimethylamine consumed in the production of dimethylformamide accounts for 44.7% of the total consumption, 38.9% in the production of pesticides, and 16.4% in the production of pharmaceuticals.

Physicochemical Property of Dimethylamine liquid

Dimethylamine liquid is gas at room temperature, with ammonia odor. Melting point -96℃, boiling point 7.4℃. Density of liquid state(0/4℃)0.680g/cm3, soluble in water, soluble in ethanol and ether. Easily combustible. Weakly alkaline, Dimethylamine CAS 124-40-3 with hydrochloric acid to produce hydrochloride with a certain melting point [(CH3)2NH-HCl] (melting point 171 ° C).

Colorless flammable gas or liquid, in high concentration or compressed liquefaction, it has a strong unpleasant ammonia odor, and in very low concentration, it has the bad odor of fish oil. Dimethylamine Raw Materials Soluble in water, soluble in ethanol and ether.

production methodprocess of Dimethylamine liquid

Dimethylamine Raw Materials can be produced by reacting methanol with ammonia under pressure to form methylamine, trimethylamine and dimethylamine, and then separated.

Mix methanol and ammonia in a certain proportion, at a certain temperature and pressure, with activated alumina as catalyst, synthesize a mixture of mono-, di- and trimethylamine, and then through heat exchange, condensation, deamination, extraction, dehydration, separation, Dimethylamine liquid.

Methanol ammoniation method. Methanol as raw material and ammonia, reaction temperature 425 ℃, reaction pressure of 2.45MPa, catalyst for α-Al2O3, methanol ammoniation gas-phase catalytic reaction of crude monomethylamine, dimethylamine and trimethylamine, and then distillation under pressure, respectively, to get single-component, purer industrial products monomethylamine, dimethylamine and trimethylamine. CH3OH + NH3 → CH3NH2 + H2O2CH3OH + NH2 + H2O2CH3OH + NH2 + H2O2CH3OH + NH2 + H2O2CH3OH + NH2 + H2O2CH3OH + H2O3 H2O2CH3OH+NH3→(CH3)2NH+2H2O3CH3OH+NH3→(CH3)3N+3H2O
