Abstract:
1. A method for producing a 1,2-diol compound represented by the general formula [2]: wherein R 1 , R 2 , R 3 , and R 4 independently represent a hydrogen atom or an alkyl group having 1-30 carbons in a straight or branched chain with or without a substituent selected from an alkoxy group, an alkoxycarbonyl group, a sulfonic acid group, a cyano group, a nitro group, a hydroxyl group, or a carboxyl group, or wherein any two of R 1 , R 2 , R 3 , and R 4 lose a hydrogen atom to be bonded together to form a cycloalkane ring with a carbon atom bonding to any two of R 1 , R 2 , R 3 , and R 4 , comprising reacting an olefin compound represented by the general formula [1]: wherein R 1 , R 2 , R 3 , and R 4 are as defined above, with hydrogen peroxide in the presence of a polymer compound having a sulfonic acid group (with the proviso that a silicon oxide-titanium oxide based synthetic zeolite is not used as a catalyst in combination with the polymer compound).
