A method for preparing thiol compounds
-
Paragraph 0040-0041, (2017/05/12)
The invention provides a preparation method of a thiol compound. According to the preparation method, gas-liquid reaction is carried out on sulfuretted hydrogen and an organic compound containing carbon-carbon double bonds in a solid base catalyst and a reaction solvent through Michael addition under the conditions that the temperature is 20-80 DEG C and the pressure is 0.10-0.12MPa, so as to prepare the thiol compound. The preparation method is mild in reaction condition; the adopted solid base catalyst is strong in alkalinity; the alkaline catalysis position has relatively strong steric hindrance, and the applicability is wide; the solid base catalyst is easy to filter and recover, and can be repeatedly used after being activated; the reaction conversion rate and the selectivity are high; the side reaction is reduced; and the atomic economic utilization rate of the reaction is high.
