Procedure

By following the same procedure as Example 20 (2nd step) except that 19.1 g of N,N-dimethylmorpholinium methyl carbonate, 19.1 g of water, and 9.8 g of maleic anhydride were used, 23.0 g (yield of 99.9%) of N,N-dimethylmorpholinium 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.
