Procedure

Triethanolamine (99% pure, Aldrich) and water as specified in Table 2 was added into a 500 ml beaker for each of the following examples. The beaker was heated to 50° C. on a hot plate with magnetic agitation. A preweighed amount of maleic anhydride briquett (100%, Huntsman) was then added to the triethanolamine water solution. After all the maleic anhydride was dissolved, the mixture was cooled and was ready for further blending.
