摘要： This invention discloses a method of immobilizing an enzymatically active material to a water-insoluble polyanion which comprises bringing a polycation-containing aqueous medium and the enzymatically active substance into contact with the water-insoluble polyanion having any desired form. This method is characterized in that the enzymatically active substance is adsorbed on the surfaces of the water-insoluble polyanion and, at the same time, a strong complex is formed by the interaction of the polycation and the polyanion to produce a water-insoluble film. As a result, the enzymatically active substance so adsorbed is securely fixed to the surfaces of the water-insoluble polyanion and scarcely released therefrom.

摘要： A continuous method for producing tert-butyl alcohol from water and isobutylene in the presence of a strongly acidic cation exchange resin as a catalyst is characterized by: said catalyst particles being filled in a reactor, a liquid isobutylene being continuously brought into contact with water such that said liquid isobutylene is filled in a continuous phase in the gaps between said catalyst particles, and that water streams downwardly along the surface of said catalyst particle and subsequently the reaction mixture being continuously taken out from the reactor. According to the method of this invention, tert-butyl alcohol is obtained in a high yield with little formation of by-products.
