Procedure
By following the same procedure as Example 20 (2nd step) except that 18.9 g of N,N-dimethylpiperidinium methyl carbonate, 18.9 g of water, and 9.8 g of maleic anhydride were used, 22.9 g (yield of 100%) of N,N-dimethylpiperidinium maleate was obtained. The content of monomethyl maleate was less than 0.1% and the content of impurity ions were all less than 1 ppm.
