摘要:The present invention relates to the synthesis of nanoparticles by laser hydrolysis. For this purpose, a precursor interacts with a laser beam (LAS) in a pyrolysis reactor (REAC) for producing nanoparticles (nP), characterized in that the precursor is firstly in the liquid state and is then converted into the vapor phase and in that the flow rate of the precursor is controlled in the liquid phase.

标题 :Process for direct synthesis of (meth)acrolein from ethers and/or acetals
发明人：DUBOIS JEAN-LUC
权利人:ARKEMA FRANCE
摘要:The subject matter of the present invention is a process for direct synthesis of (meth)acrolein from a reactive mixture comprising at least one compound chosen from ethers, acetals or hemiacetals derived from linear alcohols comprising from 1 to 3 carbon atoms. Examples of compounds are dimethyl ether, diethyl ether, methyl ethyl ether, dimethoxymethane, diethoxymethane, dipropoxymethane, 1,1-dimethoxyethane or 1,1-diethoxyethane. The process of the invention comprises two successive phases: oxidation then aldol condensation, which can be carried out in the presence of a solid oxidation catalyst chosen from molybdenum-based catalysts and optionally of an aldol condensation catalyst. These two phases are carried out in a reaction system comprising a single reactor or optionally two reactors in cascade.

权利人:MITSUBISHI GAS CHEMICAL CO
摘要:A catalyst composition comprising copper oxide, zinc oxide and zirconium oxide, the content of zirconium oxide being 30 to 70% by weight. This catalyst composition is useful for synthesis of methanol from carbon monoxide and/or carbon dioxide and hydrogen by a gas-liquid-solid phase fluidized bed method or a gas-solid phase fluidized bed method.

标题 :Process for synthesis of Di(meth)acrylic acid esters

摘要:A process for the synthesis and recovery of di(meth)acrylic acid esters at a high degree of purity. Di(meth)acrylic acid esters are produced by transesterfication of (meth)acrylic acid esters of C1 to C4 alcohols with 1,n-diols (where n>=3) in the presence of a zirconium catalyst that comprises a chelate of zirconium with a 1,3-dicarbonyl compound. These catalysts can be readily separated or removed from the reaction mixture by precipitation with phosphoric acid, thus providing a convenient and inexpensive method of producing a di(meth)acrylic acid ester with a reduced level of zirconium.

摘要:Synthesize a nickel oxide-based oxidative dehydrogenation catalyst via a solvent-free process that comprises sequential steps a. mixing without added solvent a combination of a solid nickel precursor, a solid oxalate or oxalic acid and, optionally, a doping amount of a metal precursor for a period of time sufficient to convert the combination to a visually homogenous mixture; and b. calcining the visually homogeneous mixture at a temperature within a range of from greater than 250° C. to less than 800° C. for a time within a range of from 30 minutes to 360 minutes in an oxygen-containing atmosphere, preferably air, to form a calcined oxidative dehydrogenation catalyst. As a modification of the process, add an intermediate step between steps a. and b. to dry the homo geneous mixture at a temperature within a range of from 50° C. to 90° C. for a period of time within a range of from 10 minutes to 600 minutes to form a dried mixture. The resulting catalyst may be used in oxidative dehydrogenation of ethane.
