摘要： Disclosed is a novel catalyst for use in producing a carboxylic ester from an aldehyde, an alcohol and molecular oxygen, which comprises a carrier having supported thereon Pd and Pb in a Pd/Pb atomic ratio (S) of 3/0.7.ltoreq.S.ltoreq.3/1.3, and which exhibits a maximum intensity peak at a diffraction angle (2.theta.) in the range of from 38.55.degree. to 38.70.degree. in a powder X-ray diffraction pattern thereof, wherein the peak is ascribed to the (111) crystal face diffraction of a Pd--Pb intermetallic compound. The catalyst can be efficiently produced by subjecting a catalyst precursor comprising a carrier having supported thereon a reducible Pd compound or a mixture of a reducible Pd compound and a reducible Pb compound to a reduction treatment in the presence of lead ions and at least one compound selected from a lower fatty acid, an alkali metal salt and an alkaline earth metal salt, or by subjecting a catalyst prepared by a conventional method, which comprises a carrier having supported thereon Pd or a mixture of Pd and Pb, to an activation treatment. By using the catalyst, the desired carboxylic ester can be produced with high selectivity, while suppressing the formation of by-products, even under high temperature and high aldehyde concentration conditions. Further, in the continuous production of a carboxylic ester using the catalyst, stabilization of the catalyst can be effectively performed, so that a desired carboxylic ester can be stably produced with high efficiency and in high yield for a prolonged period of time.

摘要： A method for acylating a hexakis (arylmethyl) hexaazaisowurtzitane (WB6) by reductively removing the arylmethyl groups in the presence of an acylating agent, characterized by contacting a WB6 (a) with a heterogeneous system reduction catalyst (b) in the presence of an acylating agent (c) and a reducing agent (d) in a solvent (e) for the WB6 (a) to reductively remove the arylmethyl groups from the WB6 (a) and acylate the same, and by preventing the WB6 (a) and the catalyst (b) from being contacted with each other when at least either of the acylating agent (c) and the reducing agent (d) is not present. In this method, the decomposition of the WB6 skeleton, which readily occurs in the beginning of the acylation of the WB6 as a starting material, can be highly effectively inhibited. This method can hence stably produce a tetraacylhexaazaisowurtzitane derivative in a high yield and is industrially advantageous.
