    Abstract: PROBLEM TO BE SOLVED: To carry out a reaction while controlling the concentration of a specific composition in a mixture and control the selectivity of the chemical reaction by a method comprising the fractionation of a solution of a mixture of compounds of chemically equilibrium state and reacting the fractionated part with other compound. SOLUTION: A solution of a mixture of two or more kinds of compound of chemically equilibrium state is made to react, separately from a reaction of a polyoxymethylene glycol, formaldehyde monomer and/or a formaldehyde solution containing methylene glycol with aniline in the presence of an acid catalyst, with at least one kind of other compound 9. The reaction is carried out by (A) fractionating the mixture into at least two parts (the necessary part 5 and the remaining part 6) containing the different compounds in the mixture existing at a high concentration relative to the chemically equilibrium state by a separation method and (B) reacting a fractionated part 5 with the compound 9 by a main reactor 2 before the complete reforming of the chemical equilibrium to obtain the objective product 10.

    Abstract: The invention relates to a process for obtaining anhydrous or substantially anhydrous formic acid, in which firstly aqueous formic acid is produced by hydrolysis of methyl formate, with the methanol content in the methyl formate having been reduced in advance. The process according to the invention has the special feature that-before the hydrolysis of the methyl formate-the methanol content of the methanol-containing methyl formate is reduced in a distillation column, this distillation column simultaneously being employed for other separation functions during work-up of the formic acid.
