3. Uses:
Dimethylamine is mainly used as rubber vulcanization accelerator, leather dehairing agent, medicine, pesticide, textile industry solvent, dye, explosive, propellant and organic dimethylhydrazine, N,N-dimethylformamide, etc. Raw materials for intermediates, as well as for organic synthesis and precipitation of zinc hydroxide, etc.
Among them, the consumption of dimethylamine in the production of dimethylformamide accounted for 44.7% of the total consumption, the consumption of pesticide production accounted for 38.9%, and the consumption of pharmaceutical production accounted for 16.4%;
dimethylamine is an important intermediate of pesticides and can be used to prepare fungicides Tetramethylthiuram disulfide, fumei arsine, Zinc Dimethyldithiocarbamate, fumei nickel, fumei arsenic, bacteriocin, dimethysol; insecticides pirimicarb, fendicarb, fenfentanone, fendicarb, fenboth; herbicide green Melon, isoproturon, cycloazinone, fluoxuron, etc.;
dimethylamine can also be used as analytical reagent, acid gas absorbent, basic organic chemical raw material auxiliaries, and organic synthesis intermediates;
4. Packaging, storage and transportation:
Dimethylamine is filled in tank trucks or steel cylinders, and the dimethylamine aqueous solution is packed in 200L iron drums.
Dimethylamine should be sealed and stored in a cool and ventilated place, avoid sunlight and use devices that are prone to static electricity, and prevent violent impact and vibration.
5. Physical and chemical properties:
Dimethylamine is a colorless gas at room temperature, with strong ammonia odor, boiling point 6.880C, soluble in water, soluble in ethanol and ether, flammable, weakly alkaline, and easily soluble with inorganic acids salts in water . Commodities are supplied as liquefied products or 40% aqueous solution, of which the density of 40% aqueous solution is 0.898 and the boiling point is 51.50C.
