摘要:A process for the production of a fluorinated quartz glass including the steps of generating SiO2 particles in a synthesis burner; depositing the resulting SiO2 particles into a body; and vitrifying the resulting body, wherein a fluorinating agent having a boiling point greater than or equal to −10° C. is supplied to the synthesis burner.

摘要:Catalysts and catalytic processes for the synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, which are carried out in a diluent or in the absence of a diluent. In an aspect, ethylene and CO2 can be contacted with a Group 8-11 transition metal precursor compound or a Group 8-11 transition metal metalalactone compound in the presence of a metal-treated chemically-modified solid oxide (MT-CMSO) or a metal-treated solid oxide (MT-SO), to form a metal acrylate. As the catalytic activity wanes in either the presence or absence of a diluent, pressure cycling—that is, pressurizing the reaction system with CO2 and an olefin such as ethylene for a time period, releasing the pressure, then re-pressurizing with CO2 and ethylene—can rejuvenate the catalyst and restore its declining catalytic activity.

摘要:Method of preparing a catalyst comprising catalytic species consisting of transition metals deposited on a support, comprising the steps of contacting a solution of a metal-carbonyl or other organometallic complex of the transition metal with a support, carrying out the deposition and the surface interaction of the transition metal on the surface of the support and causing the carbonyl metal or the organic complex to decompose as a result of at least one heat treatment. The catalyst obtained is advantageously used in the production of synthesis gas and in other high temperature industrial chemical processes.
