We have provided a new synthetic method of T.M.D using Oxalic acid andhydrochloric acid simultaneously as catalysts on the basis of the predecessor'swork and have also offered optimum condition of synthesizing it by meansof crossing tests and examinatorial experiments. Thus, the yield of productis raised to more than 90 per cent which is higher by far than that of theclassical method by using hydrochloric acid alone as catalyst. we have iden-tified the structures of the organic compounds and suggested a possible mech-anism for T.M.D synthesis with acid catalyst. The function of oxalic acidon raising the yield is also elucidated. Synthetic product T. M.D has beenused as system of epoxy resin--maleic anhydride and has been an excellentaccelerator by revealing datum.
