(±)-sec-Butylamine Use and Manufacturing

Methods of Manufacturing

The preparation method is obtained by the action of methyl ethyl ketone and ammonia. Add methyl ethyl ketone and Raney nickel to the autoclave, add gaseous ammonia after evacuating the air, heat to 160℃, pressure to 4MPa, and then hydrogenate to pressure 6MPa, hydrogenate 3 times before and after, all react for 10h, and let it stand overnight. Cool down to room temperature, discharge the material, filter out the nickel powder, add dilute sulfuric acid under ice water cooling, the temperature does not exceed 30 ℃, steam distill the sulfate to remove sec-butanol, the resulting sulfate solution is concentrated under reduced pressure and dehydrated Obtain sec-butylamine sulfate, add alkali for fractional distillation and refining to obtain finished products.

Uses

It is mainly used as an organic raw material for the synthesis of drugs, dyes, and pesticides, dextromethamine herbicides, etc.

Material

Methyl ethyl ketone

Naphthalene

Methyl ethyl ketoxime
