Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an O-alkyl substituted polysaccharide derivative efficiently and in high purity and to provide a method for producing an optically active substance using the derivative obtained by the method. SOLUTION: The method for producing the derivative comprises 1) a step for subjecting a polysaccharide to the alkylation, 2) a step for removing the non-reacted materials and/or the byproduct impurities in step 1 and 3) a derivative step for producing a derivative of the resulted and purified alkylated polysaccharide. The method for producing the substance uses a separating agent having the derivative obtained by the method as an active ingredient and it consists of contacting a mixture of a classificating solution comprising the derivative obtained by the method and a diluent, a desorbent and an optical isomer with a sorbent comprising a porous material.

Abstract: PROBLEM TO BE SOLVED: To provide a high purity isomer from a mixture of isomers continuously in a high productivity. SOLUTION: This method for adsorbing and separating isomers by bringing a discriminating liquid consisting of a discriminating agent having molecule- discriminating capacity and a diluent, a desorbing agent and a mixture of isomers in contact with an adsorbent consisting of a porous material for separating a specific isomer, is provided by performing a treatment for improving the discriminating capacity of the discriminating agent contained in the discriminating liquid and then re-using the above discriminating liquid for the separation of the mixture of the isomers.

Abstract: PROBLEM TO BE SOLVED: To provide a method for continuously producing a high-purity optically active substance without causing decline in its separatory performance even under the continuous production process. SOLUTION: This method for producing an optically active substance comprises isolating a specific optical isomer by contacting a mixture of a discriminating liquid comprising a discriminating agent and a diluent, a desorbing agent and an optical isomer with an adsorbent of porous matter, wherein this method involves the step of isolating and recovering the discriminating agent and the optically active substance from an effluent followed by removing impurities from the discriminating liquid recovered.

Abstract: PROBLEM TO BE SOLVED: To selectively and efficiently obtain the subject compound useful as a raw material for medicines. SOLUTION: An aromatic ketone compound (e.g. p-methylbenzophenone) substituted by a 1-7C alkyl group and/or a halogen group (chlorine and/or bromine) is brought into contact with a catalyst containing a zeolite, preferably at 20-350 deg.C under a pressure capable of keeping liquid phase to provide the objective specific isomer of an aromatic ketone. The zeolite used in this reaction is preferably at least one kind of zeolite selected from beta type, pentasil type, mordenite type and faujasite type zeolites.

Abstract: PURPOSE: To separate a high-purity ethyl phenol isomer in a high yield by using a specific adsorbent, adsorbing and separating a prescribed isomer useful as an intermediate for a medicine, a color coupler, etc., from an ethylphenol isomer mixture. CONSTITUTION: A prescribed ethylphenol isomer is adsorbed on and separated from (B) an ethylphenol isomer mixture by using (A) an X type zeolite adsorbent (e.g. containing a metal such as Li, K, Rb, Cs, Mg, Ca, Sr, Ba, Pb, etc., and 1-10wt.% of water based on the adsorbent). For example, a mixture comprising m-ethylphenol (B1 ), p-ethylphenol (B2 ) and one or more alkyl phenols is used as the component B, the component B1 is adsorbed on and separated from the component B containing the component B1 , the component B2 and one or more alkylphenols by using the component B containing Mg, Ca or Sr and the component B2 is adsorbed on and separated from the component B by using the component B containing K or Ba.
