The enthalpies of formation of some compounds are not easy to be measured experimentally. This paper reports the calculated values of the heat of formation for some novel moleclar sieves by a method of consistant molecular mechanics force field. The enthalpies of formation of novel type molecular sieves: ZSM-48, ZSM-22, ZSM-23 and ZSM-18, have been calculated.

Key words: Enthalpy of formation, ZSM-48, ZSM-22, ZSM-23, ZSM-18
