Conditions

Temperature: 120 °C

Procedure

22.6 g of 2-hydroxy-4-octoxy-benzhydrazide are dissolved in 200 ml of dimethylacetamide at 60° C and treated with a solution of 10 g of 2-(di-n-propylamino)-4,6-dichloro-s-triazine in 50 ml of dimethylacetamide whilst keeping the temperature constant. The reaction mixture is heated to 120° C over the course of 3 hours. After cooling, it is poured into one litre of water, whereupon the product precipitates as a white solid. After filtration, it is dried and recrystallised from ethylene glycol-monomethyl ether. 2-(Di-n-propylamino)-4,6-di-(2-hydroxy-4-octoxybenzoylhydrazino)-s-triazine (Stabiliser No. 21) is thus obtained in the form of a white powder of melting point 195° - 196° C.
