    摘要: Disclosed are a process for the preparation of a dihydroxyamino compound in which water and discoloring ingredients are removed while preventing decomposition of a dihydroxyamino compound by distilling a crude reaction liquid containing an epoxy compound and an amino compound at a specified temperature and pressure, a process for improving a yield of a dihydroxyamino compound having high purity by recirculating an aqueous solution of an amino compound recollected from a crude reaction liquid into a reaction step, and a process in which there are prevented discoloration and a yield decline of a dihydroxyamino compound.
