    A METHOD FOR ISOLATING DIIZOPROPANOLAMINE from a mixture containing oxaolidone, the resultant washing of natural oil gas with a high content of hydrogen sulfide with a solution containing diisopropanolamine by hydrolysis of this mixture in the presence of water at 140-180 ° C with subsequent separation of water from the reaction mixture characterized in that, in order to simplify the process, water is taken in a 1-4-fold mass excess with respect to oxazolidone.
