Abstract: A process for the production of a heteroaromatic carboxylic acid comprising contacting in the presence of a catalyst, a precursor of said carboxylic acid with an oxidant, such contact being effected with said precursor and the oxidant in an aqueous solvent comprising water under supercritical conditions or near supercritical conditions close to the supercritical point.

CPC classification number: C07D201/08
Abstract: A process for the manufacture of a lactam from an amino alkane nitrile and/or its hydrolysis derivatives, comprising reacting a solution comprising at least about 5% by weight amino alkane nitrile in water at a temperature of greater than or equal to about 350°C and at a pressure of greater than about 250 bar. Optionally, a dilute acid may be added as a catalyst.

Abstract: A process for the production of an aromatic carboxylic acid comprising contacting in the presence of a catalyst, within a continuous flow reactor, one or more precursors of the aromatic carboxylic acid with an oxidant, such contact being effected with said precursor(s) and the oxidant in an aqueous solvent comprising water under supercritical conditions or near supercritical conditions close to the supercritical point such that said one or more precursors, oxidant and aqueous solvent constitute a substantially single homogeneous phase in the reaction zone, wherein the contact of at least part of said precursor with said oxidant is contemporaneous with contact of said catalyst with at least part of said oxidant.

Abstract: A process for the simultaneous or sequential production in the same reaction zone of two or more dicarboxylic acids selected from orthophthalic acid, isophthalic acid and terephthalic acid comprising contacting simultaneously or sequentially in the presence of a catalyst, one or more precursors of each of at least two dicarboxylic acids selected from orthophthalic acid, terephthalic acid and isophthalic acid with an oxidant, such contact being effected with said precursors and the oxidant in an aqueous solvent comprising water under supercritical conditions or near supercritical conditions close to the supercritical point is disclosed. In preferred embodiments, the process is for the simultaneous or sequential production in the same reaction zone of orthophthalic acid, terephthalic acid and isophthalic acid.
