Abstract
The invention relates to a preparation method of 1, 2-propane diamine. The method has the advantages that 1, 2-propane diamine can be directly generated by using epoxypropane, the method is mild in reaction condition, a gas-solid phase reaction is adopted, the corrosion of a liquid phase material to reaction equipment under high-temperature and high-pressure conditions is avoided, the requirement on the material of the equipment is low, full-continuous production can be realized, the raw material conversion per pass is high, and the product selectivity is good. Generated monoisopropanolamine and diisopropanolamine are sold as byproducts after being purified, the utilization rate of raw materials is high, and generated other substances are few.
