摘要： A method of removing SO.sub.2 from a gas stream containing the same by absorbing the SO.sub.2 in an aqueous solution containing a 4-(2-hydroxyalkyl)-2-piperazinone compound or an alkyl or aryl substituted derivative thereof. These compounds provide an absorbent solution which is less subject to loss during the regeneration step and yet effectively remove the SO.sub.2 from the gas stream without interference from other associated gases.

摘要： A process for the preparation of 4-(2-hydroxyalkyl)-2-piperazinones and their substituted derivatives comprising reacting an N-hydroxyalkylalkylenediamine, e.g. 2-[(2-aminoethyl)amino]ethanol, or a hydrocarbyl substituted derivative thereof with an .alpha.,.beta.-dicarbonyl compound, e.g. glyoxal, an alkyl-substituted derivative of glyoxal or a glyoxal equivalent. Certain hexahydro-4-(hydroxyalkyl)-2H-1,4-diazepin-2-ones have been made which are new compounds.
