Procedure

By following the same procedure as Example 20 (2nd step) except that 7.8 g of ethyltrimethylammonium methyl carbonate, 7.8 g of water, and 4.7 g of maleic anhydride were used, 9.7 g (yield of 99.9%) of ethyltrimethylammonium maleate was obtained. The content of monomethyl maleate was less than 0.1% and the contents of impurity ions were all less than 1 ppm.
