    摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing an aromatic polycarboxylic acid polychloride useful as an intermediate of pharmaceuticals and agrochemicals or as a production raw material of functional polymers, particularly a method for simply and inexpensively manufacturing in a high yield an aromatic polycarboxylic acid polychloride of high purity indispensable for manufacturing functional polymers such as an aromatic polyimide, an aromatic polyester and the like.SOLUTION: An aromatic polycarboxylic acid having a sodium content of 150 ppm or less obtained by washing, with water, an organic solvent or a mixture thereof, an aromatic polycarboxylic acid obtained by an oxidation reaction of a polyalkyl aromatic hydrocarbon, is reacted with a (trichloromethyl)benzene compound using a catalyst comprising a chloride or an oxide of iron or zinc, and the resultant product is subjected to distillation purification to give the aromatic polycarboxylic acid polychloride.

    摘要： PROBLEM TO BE SOLVED: To provide a method for producing a substituted benzoyl chloride in high yield, conversion and selectivity with a simple procedure without necessitating a large amount of additional expenditure. SOLUTION: The benzoyl chloride of formula (1) (R is a substituted or non- substituted phenyl, a halogen, NO2, CN, NR'2, OR', SO2R', SO2OR', COR' or CO2R'; R' is an alkyl, phenyl or a substituted phenyl; (x) is 1 or 2; and (y) is 1, 2 or 3) is produced by reacting a benzaldehyde of formula (2) (R, (x) and (y) are same as those defined above) with a chlorination agent in the presence of a free radical initiator and a solvent at -20 to +200 deg.C.

    摘要： PROBLEM TO BE SOLVED: To provide a method for separating a reaction product from a catalyst, in which the reaction product from the catalyst and/or the changed catalyst can be separated, by simple operations where an imide compound such as N- hydroxyphthalimide is used as the catalyst and a hydrocarbon or the like as one of solvents. SOLUTION: This method for separating the reaction product from the catalyst and/or the changed catalyst in a reaction mixture obtained by a reaction in the presence of an imide compound catalyst represented by the general formula (1) (R1 and R2 are each H, an alkyl or the like, provided that R1 and R2 may be bound to each other to form a double bond or an aromatic or non- aromatic ring; X is oxygen atom hydroxyl group), characterized by using an aqueous solvent containing at least water and a non-aqueous solvent capable of being separated from the aqueous solvent. Thus the reaction product is separated in the non-aqueous solvent layer and the imide compound catalyst or its changed product in the aqueous solvent layer, respectively.
