Title:
A manufacturing method of xylene
Document Type and Number:
Japanese Patent JP6254882
Kind Code:
B2
Abstract:
Provided is a method for producing xylene with high yield by selecting an adequate starting material oil in cases where xylene is produced by subjecting a starting material oil composed of a petroleum fraction to a disproportionation reaction or a transalkylation reaction. A method for producing xylene by subjecting a starting material oil, which comprises a petroleum fraction as a base material, to a transalkylation reaction or a disproportionation reaction. This method for producing xylene is characterized in that an oil, which contains an alkyl benzene having 7-10 carbon atoms or the like, and wherein the average number of methyl groups directly bonded to each benzene ring of the alkyl benzene or the like is 1.2 to 2.8, is used as the starting material oil.
