摘要： PURPOSE: To prepare the titled substance with little production of the condensation by product, by reacting xylylenediamine with a nitrous acid salt in the presence of a lower aliphatic carboxylic acid and water to obtain a mixture of the titled substance and its mono- and dicarboxylic acid ester, and hydrolyzing the ester.
CONSTITUTION: Xylylenediamine is made to react with a nitrous acid salt (e.g. sodium nitrite) in the presence of a lower aliphatic carboxylic acid (preferably acetic acid) and water at 60W100°C to obtain a mixture of the titled substance and its mono- and dicarboxylic acid esters. The carboxylic acid is neutralized by adding an alkaline aqueous solution to the mixture, and the mixture is made alkaline with an alkali, hydrolyzed at 60W80°C under agitation, and treated with an organic solvent to extract the objective substance. The extraction residue composed mainly of sodium acetate is added with concentrated sulfuric acid to regenerate acetic acid at ≤25°C, and the acetic acid is recycled to the reaction system.
EFFECT: The use of a large amount of acetic acid is not necessary, and the amount of waste water can be reduced.
USE: A raw material of polyurethane, etc. or a modifier.

摘要： PURPOSE: In preparing an olefin from methanol and/or dimethyl ether, to reduce the amount of a diluent used, to improve rate of reaction and selectivity, to prevent a catalyst from deteriorating, by reducing rate of feed of a raw material per crosssectional area of catalytic layer and per hour.
CONSTITUTION: Using a catalyst comprising crystalline aluminosilicate zeolite (e.g., FZ-1 zeolite, etc.), olefin is prepared from methanol and/or dimethyl ether by a catalytic reactor of fixed bed. In the reaction, methanol and/or dimethyl ether are fed in amounts in range from 0.3W15g per sec per crosssectional area of catalyst, and the amount of a diluent used is reduced. The heat of reaction produced per crosssectional area of catalytic layer in a direction perpendicular to the direction of the raw material and per hour can be made small. The reduction in the amount of the feed of the diluent can save energy.
