Dimethylamine is an important organic chemical raw material, widely used in pesticides, pharmaceuticals, dyes, rubber additives and other fields. The upstream and downstream related products of dimethylamine mainly include the following aspects:

upstream products:

1. Methanol: The production of dimethylamine mainly uses methanol as raw material and is synthesized through process steps such as amination and dehydrogenation.

2. Ammonia: Ammonia is another important raw material in the production of dimethylamine, which reacts with methanol to form dimethylamine. Downstream products of

:

1. N,N-dimethylformamide (DMF): Dimethylamine reacts with formic acid to generate N,N-dimethylformamide, which is an important solvent and chemical raw material.

2. Dimethyl ammonium sulfide (DMS): dimethylamine reacts with hydrogen sulfide to form dimethyl ammonium sulfide, which is a commonly used rubber additive.

3. Dimethylacetamide (DMAC): Dimethylamine reacts with acetic anhydride to form dimethylacetamide, which is an excellent solvent and chemical intermediate.

4. Pesticides: Dimethylamine can be used to synthesize a variety of pesticides, such as dimethylamine-based avermectin, dimethylamine-based pyrimidine, etc.

5. pharmaceutical intermediates: dimethylamine can be used for the synthesis of a variety of pharmaceutical intermediates, such as dimethylamino propanol, dimethylamine ethanol and so on.

In short, dimethylamine, as an important organic chemical raw material, has a wide range of upstream and downstream related products, which is of great significance to the field of chemical production raw materials.
