摘要： A method of producing an ethylenically unsaturated carboxylic acid or ester, preferably an α, β ethylenically unsaturated carboxylic acid or ester. The method includes contacting formaldehyde or a suitable source thereof with a carboxylic acid or ester in the presence of a catalyst and optionally in the presence of an alcohol. The catalyst includes a nitrided metal oxide having at least two types of metal cations, M1 and M2, wherein M1 is selected from the metals of group 2, 3, 4, 13 (called also IIIA) or 14 (called also IVA) of the periodic table and M2 is selected from the metals of groups 5 or 15 (called also VA) of the periodic table.

摘要： Disclosed are a joint production method and device for aziridine, piperazine and triethylenediamine. The method comprises: reaction 1, preparing piperazine and triethylenediamine by taking ethanol amine as a raw material under the existence of a cyclamine catalyst; reaction 2, preparing aziridine by taking the ethanol amine as the raw material under the existence of a catalyst B; and taking heat released in the reaction 1 as a heat source of heat absorption in the reaction 2. The device comprises a reactor 1 for carrying out the reaction 1 and the heat exchange between reaction materials of the reaction 1 and the raw material of the reaction 2 and a reactor 2 for carrying out the reaction 2. According to the present invention, the same raw material, namely the ethanol amine is adopted, aziridine, piperazine and triethylenediamine can be produced in a joint manner, the heat released in the reaction 1 is used for preheating materials in the reaction 2, so that heat coupling between the reactions is implemented, energy conservation is facilitated and competitiveness of the device is improved.

摘要： Disclosed herein is a mixed phosphate catalyst for converting lactic acid to acrylic acid, which is characterized by a high conversion of lactic acid, a high selectivity for acrylic acid, a high yield of acrylic acid, and correspondingly low selectivity and molar yields for undesired by-products. This is achieved with a particular class of catalysts defined by a mixture of metal-containing phosphate salts. Further, the catalyst is believed to be stable and active for lengthy periods heretofore unseen in the art for such dehydration processes.
