Procedure

By following the same procedure as Example 20 (2nd step) except that 8.8 g of methyltriethylammonium methyl carbonate, 8.8 g of water, and 4.5 g of maleic anhydride were used, 10.6 g (yield of 100%) of methyltriethylammonium maleate was obtained. The content of monomethyl maleate was less than 0.15 and the contents of impurity ions were all less than 1 ppm.
