Reaktionsschritte

To a four neck round bottom flask fitted with nitrogen inlet, mechanical stirrer, temperature probe and condenser is charged 994.13 g (2.24 moles) of the Alkoxylate from example 27 and 605.87 g (2.13 moles) of Stearic Acid. A catalytic amount of Methanesulfonic Acid (1.6 g) is charged and the reaction mixture is heated to 220° C. under nitrogen sparge. The reaction is monitored by measuring the acid value to an AV of preferably less than 5. Once the AV is reached, the temperature is cooled to 85° C. and the catalyst is neutralized with an equivalent molar amount of 45% KOH and washed once with water. The reaction is dried under vacuum yielding the desired product.
