CYANOPYRIDINE MANUFACTURING METHOD, BENZONITRILE MANUFACTURING METHOD, CARBONATE ESTER MANUFACTURING METHOD, AND CARBONATE ESTER MANUFACTURING APPARATUS

摘要

[Problem] To provide a method for performing regeneration from picolinamide or benzamide to cyanopyridine or benzonitrile without using strong reagents and while also limiting generation of by-products. [Solution] To solve said problem, one embodiment of the present invention provides a cyanopyridine manufacturing method characterized in that the cyanopyridine is manufactured by heating picolinamide in the presence of a catalyst loaded with an alkali metal oxide and in the presence of an organic solvent to cause a dehydration reaction. Another embodiment of the present invention provides a benzonitrile manufacturing method characterized in that the benzonitrile is manufactured by heating benzamide in the presence of a catalyst in which a metal oxide of a metal species such as molybdenum is loaded on a catalyst support obtained from SiO2, etc. and in the presence of an organic solvent to cause a dehydration reaction.
