Versuchsvorschrift
193 g (1 mol) of trimellitic acid anhydride and 234 g (1.8 mol) of 2-ethylhexanol plus 0.2 g of octylene glycol titanate were placed in a one-liter round flask. The mixture was heated to 150° C. with stirring and the introduction of nitrogen gas, and the splitting off of water begins. Within 4 hours the temperature is raised to 220° C., the distillate is separated by means of a Vigreux column, the top temperature amounts to 100° to 105° C. The bath temperature is maintained until the top temperature falls below 80° C. The product has an acid number of 150±10 mg KOH/g. 1.7 mol of 2-ethylhexanol per mol of trimellitic acid is contained in the product.
