With the use of ethylene glycolate anion as labilizable blocking agent (hydrolyzable bidentatc chelating ligand)to protect two neighboring coordination sites in the first coordination sphere of MoIV(III) of the synthesized FeMo-co modeling compound, an increase in reconstituted-nitrogenase activity of 2 orders of magnitude of the sample synthesized (as compared with the use of acetoni-trile or other monodentate ligands as blocking agents) has been obtained.

A discussion of the applicability of TVFM to zeolite-vapour systems was also given. For systems of ZSM-5-C8H6 and ZSM-5-H2O, adsorption equilibrium equations in which values n are 1.3 and 0.9 respectively were presented. Adsorption isotherms calculated over a wide range of temperature and filling and the pore volume of zeolite thus determined are in good agreement with the experimental data.
