实验过程

Maleic acid 25.5g, 0.22m) was dissolved in 30 gm. of H2O, and sodium hypophosphite monohydrate (11.33g 0.11m) was added. At 60° C., the solution was treated over 4 hours with small portions of ammonium persulfate (1.9g in all). Heating was continued 2 hours more. The solution contained monosodium phosphinico succinate. Infra-red and NMR examination showed disappearance of the maleic double bond, indicating complete adduction.
