    摘要： A process for preparing a 1,3-alkandiol from a 3-hydroxyester, comprises preparing a catalyst by adding an alkaline precipitator to an aqueous copper salt solution to form copper hydroxide particles, and aging the particles following the addition of a colloidal silica thereto; activating the catalyst by reduction with a H2 gas or a H2-containing gas and applying a pressure of about 5 psig to about 2000 psig at a temperature of about 100° C. to about 250° C. in the presence of an activation solvent; and hydrogenating a 3-hydroxyester in a liquid phase slurry with a H2 gas or a H2-containing gas and applying a pressure of about 50 psig to about 3000 psig at a temperature of about 100° C. to about 250° C. in the presence of the activated catalyst and a reaction solvent, whereby a 1,3-alkanediol can be selectively prepared from a 3-hydroxyester with a high yield.

    摘要： The present invention relates to a hydrogel contact lens having improved wettability, and particularly to a hydrogel contact lens of a complex membrane having an IPN (interpenetrating polymer network) intra structure, which is prepared by crosslinking composition for a contact lens comprising, as a main ingredient, an acryl monomer and an oligosaccharide and optionally a silicone compound. Due to the presence of an oligosaccharide in a contact lens herein, tensile strength and wettability can be maximized to provide a superior wearing feeling and maintain wettability even after a long-term storage in a care solution such as a washing solution, a storage solution and a protein-removing solution.
