Reaction Steps

42 g of 5-octadecoxy-2-hydroxybenzoic acid hydrazide are suspended in 200 ml of dimethylacetamide and 8 g of pyridine and 19.3 g of chloroformic acid n-octyl ester are added simultaneously over the course of 30 minutes. The reaction mixture is subsequently heated to 80° C for 5 hours whilst stirring, cooled and poured into 1 litre of water. This produces a white precipitate of the N-(5-octadecoxy-2-hydroxybenzoyl)-hydrazinecarboxylic acid n-octyl ester which has been formed (Stabiliser No. 9). The substance is isolated, washed with water, dried at 60° C and recrystallised from acetonitrile. Melting point 85° C.
