[Structural formula]

[Physical and chemical properties] Rosinamine is a light yellow viscous oily liquid

Slightly soluble in boiling water (0.

[Preparation]

(1) High pressure hydrogenation method

From rosin nitrile, rosin amine is prepared by catalytic hydrogenation under high temperature and high pressure

The catalytic hydrogenation of rosin nitrile is a heterogeneous catalytic exothermic reaction, using skeleton nickel as a catalyst, a small amount of sodium hydroxide as a promoter, and ethanol as a solvent

The rate of the hydrogenation reaction depends on the pressure of hydrogen and the activity of the catalyst

Industrially, 20kg of rosin nitrile, 38kg of industrial ethanol , 6kg of nickel, and 200g of sodium hydroxide are used and mixed and stirred evenly

(2) Rosin melting method

The ingredient ratio is disproportionated rosin: ammonia: red phosphorus: boric acid = 1: 0.

[Application] Rosin amine is generally packed in iron drums
