摘要:The present invention provides a method for the preparation of some novel multiconjugated 2- or 4-hydroxy substituted stilbenes. The method provides one pot multicomponent approach wherein 3-4 step reaction sequences viz. condensation, decarboxylation and Heck coupling occur simultaneously which results in an enhanced yield of desired products and reduced reaction times.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.

摘要:[Problem] The present invention addresses the problem of increasing the rate of reaction by controlling ammonium ions, which are generated by ammonia as the objective of the electrolytic synthesis of ammonia and protons that are supplied to the cathode, by means of the cathode and the cathode catalyst layer. [Solution] The present invention provides a gas diffusion electrode which is integrated with a catalyst layer that uses a material selected from the group consisting of cathode catalyst layer materials. Examples of the cathode catalyst layer materials include a fired body and an ionic liquid.

摘要:The present invention relates to a method for the depolymerization of a polyurethane mass, preferably thermoset polyurethane. The method comprises four main steps: i) mixing the polyurethane mass with a depolymerization reaction medium comprising an ionic liquid in a proportion equal to or greater than 50% w/w with respect to the total weight of said medium, a superbase as a catalyst, and a nucleophilic agent in a proportion equal to or less than 15% w/w with respect to the total weight of said medium, subjecting said mixture to a temperature between 50-100°C for between 2 minutes and 10 hours; ii) adding a mass of a protic molecular solvent in an amount between 4 and 40 times the weight of the depolymerization reaction medium; iii) subjecting the mixture from step ii) to a temperature between 20-60°C for at least 1 hour; and iv) separating the fractions obtained in step iii), namely, a semisolid fraction comprising at least a polyol mass for reuse in the synthesis of a new polyurethane, and a single-phase liquid fraction comprising at least the ionic liquid and the basic catalyst, for their reuse in a new process for polyurethane depolymerization.
