Preparation of 1,6-Hexanediamine

Preparation of 1,6-Hexanediamine
1,6-Hexanediamine is an important organic compound widely used in fields such as polymers, pharmaceuticals, pesticides, and dyes. There are several main methods for its preparation: 1. 1,6-hexanediol oxidation method. 1,6-hexanediol is oxidized to produce 1,6-hexanedione, which is then reduced to obtain 1,6-hexanediamine. The reaction equation is as follows: 1,6-hexanediol+O2 → 1,6-hexanedione 1,6-hexanedione+H2 → 1,6-hexanediol 1,6-hexanedione+NH3 → 1,6-hexanediamine. 1,6-hexanediamine is prepared by reduction with hydrogen gas under the action of a catalyst to generate 1,6-hexanediamine. The reaction equation is as follows:

1,6-Hexadiimide+H2 → 1,6-Hexanediamine. Cyclohexanone is prepared by amination with ammonia gas under the action of a catalyst, producing 1,6-Hexanediamine. The reaction equation is as follows: cyclohexanone+NH3 → 1,6-hexanediamine. All three methods have their own advantages and disadvantages, and selecting the appropriate preparation method requires consideration of factors such as cost, yield, and purity.
