| abstract | Novel process for preparing N.N'-bis(hydrocarbyloxycarbonyl)-N.N'-bis(2.2.6.6-tetramethyl-4-piperidyl)diamines Abstract of the disclosure A process for preparing a compound of the formula (I) (I) in which R1 is e.g. hydrogen, R2 is e.g. C2-C12alkylene and R3 is e.g. C1-C18aLkyl; which process comprises reacting, in water, in the absence of an organic solvent, a compound of the formula (II) C1-COOR3(II) wherein R3 is as defined above with a compound of the formula (III) (III) where R1 is e.g. as defined above and R2' is e.g. as defined above for R2, at a temperature of from 0" to 60°C, 1 to 1.5 mol of the compound of the formula (II) being used per mol -NH- group in the compound of the formula (III); and neutralising the hydrochloric acid formed with an inorganic base. |
