A flow of my study in this faculty was summerized.　This program has been started by a heterogeneous saponification of PVAc to simplify the process of making of PVA fiber. A preliminary partial saponification of PVAc shows a excellent acceleration on the reaction fate in this system. To analyze the phenomenum, a diffusion of alikali ion and pervaporation technique, for examining of diffusion of reactants, were investigated experimentaly. The pervaporation has related with my later work as follows;　1. It is found that one diffusant, in the case of existence of plural diffusants, is affected synergetically on the diffusivity by plasticizing of coexisting diffusant.　2. The cases of anomalous diffusant, like as case II, two stages and sigmoidal were examined on the systems of crystalline polymer solids and diffusants having considerable affinity.　3. The permeselective and pore size controlled inorganic membrane were pre-pared using the sol-gel technique and the forming of composites of the inorganic/organic substances or polymer. The materials was used as the catalyst for hydrogen isomerization.　4. The membrane reactor which has both catalysis and separability is examined in now to try a shift of equilibrium.
