摘要： PURPOSE: To prepare the titled compound in high rate of reaction and high conversion even at a high charging concentration of the raw materials, by reacting (meth)acrolein with methanol and molecular oxygen in the presence of Pd catalyst while removing the water from the reaction system.
CONSTITUTION: Methyl methacrylate or methyl acrylate is prepared by reacting methacrolein or acrolein with methanol and molecular oxygen in the presence of a Pd-containing catalyst at 30W90°C under pressure of 1W20kg/cm
2 . In the above process, the reaction is carried out while removing the water produced by the reaction and the water supplied to the reaction system together with the raw materials, and keeping the water content in the reaction system to preferably ≤3.5wt% throughout the whole reaction period. The removal of water is performed, e.g. by containing the reaction materials with inorganic or organic dehydrant in or out of the reaction system, or by using a proper azeotropic agent for dehydration, etc.

摘要： A process for effecting the recovery and use of a heavy metal oxidation catalyst from a high-boiling distillation residue obtained during the Witten process for the production of dimethyl terephthalate involves the extraction of the high-boiling distillation reside with water or dilute aqueous solution of low molecular weight aliphatic monocarboxylic acids or alcohols and recycling of the extract into the oxidation stage of the Witten process. In the extract the quantitative ratio of the sum of the amount of trimellitic acid and monomethyl ester of trimellitic acid to the amount of heavy metal catalyst is controlled to be at a value of no more than 1.8:1 and in the oxidation stage of the Witten process the catalyst concentration (c), expressed in p.p.m., is represented by the formula: c=44x(a/b)+d wherein a represents the sum of trimellitic acid and monomethyl ester of trimellitic acid, b is the amount of heavy metal oxidation catalyst within the extract, and d is in a range of from 60 to 300 p.p.m.

摘要： PURPOSE:The oxidation of an aldehyde and an alcohol with molecular oxygen is conducted in the presence of a specific catalyst to produce a carboxylic ester in one-stage procedure in high yield and selectivity. CONSTITUTION:An aldehyde such as isobutyladehyde or methacrolein and an alcohol such as methanol are oxidized with molecular oxygen in the presence of a catalyst consisting of at least one of Pd and its compounds and at least one of lead and its compounds at 0-100 deg.C under atmospheric pressure to porduce the objective compound such as ethyl isobutyrate or methyl methacrylate. The Pd compound is, e.g., its acetate, formate, sulfate or others; the lead compound is, e.g., its acetate, sulfate, stearate, naphthenate, oxide or hydroxide. The above catalyst can be supported on a carrier such as alumina, activated carbon, calcium carbonate or two catalysts can be supported with each other with no use of usual carrier.
