Reaction Conditions

Reaction Steps

To a 1-liter heated resin kettle equipped with agitator, thermometer, condenser and Dean Stark trap, 168 g glycerin (5.48 equivalents) was added and heated to 70-80° C. Under agitation, 400 g adipic acid (5.48 equivalents) was added in shots. The batch of glycerin and adipic acid was heated to 150-200° C. and water removed at atmospheric pressure using a Dean Stark trap. Water was continuously removed from the Dean Stark trap as it distilled over. The temperature that the water began to distill was 150-160° C. The amount of water collected was 50 g, which is 51% of theoretical (98.6 g). Gelation began to occur after about 73% of the water was removed (72 g of water in this case).
