Reaction Conditions

Reaction Steps

Into a two liter-flask equipped with a central stirrer, a thermometer and a vertical condenser fitted to a receptacle, were introduced 1440g (4.25 mols) of behenic acid and 219.5g (1.6 mol) of trimethylolpropane. The reaction medium was slowly heated, under nitrogen atmosphere, until the medium was completely melted and 1.4g of sodium hydroxide pastilles, dissolved in a minimum of water, were added. The reaction medium was gradually heated to a temperature which provoked distillation of the water in the medium, without causing distillation of the trimethylolpropane. The medium was then heated to 220° C and this temperature was maintained for about 4 hours until the acid number was about 4. After cooling to 90° C, the medium was decoloured by means of hydrogen peroxide (200 volumes). The temperature was maintained at 90° to 95° C for 30 minutes and the molten material was poured onto a stainless steel plate. After cooling, 1550g of trimethylolpropane tribehenate were obtained.
