Publication number: 20240034709Abstract: A continuous process can be used for preparing methacrylic acid by catalytic hydrolysis of methyl methacrylate that has been prepared proceeding from C-2, C-3, or C-4 raw materials. In this process, methyl methacrylate of high purity is reacted with water in the presence of a Brønsted catalyst to give a reaction mixture containing the reactants and products and worked up in a distillation column. In the distillation column, a condensate containing an azeotrope of MMA with methanol is produced at the top, a vapour condensate containing methacrylic acid of high purity is produced in the middle part of the column, and a substance mixture containing high-boiling by-products and a small amount of methacrylic acid is obtained in the bottom of the column.Type: ApplicationFiled: March 7, 2022Publication date: February 1, 2024Applicant: Röhm GmbHInventors: Steffen Krill, Daniel Helmut König, Dirk Bröll

Publication number: 20240010604Abstract: An improved process for synthesizing methacrylic acid and/or alkyl methacrylates, in particular methyl methacrylate (MMA), involves reacting acetone and hydrogen cyanide in the presence of an alkaline catalyst in a first reaction stage such that a first reaction mixture containing acetone cyanohydrin (ACH) is obtained. The process then involves working up the first reaction mixture containing acetone cyanohydrin (ACH), reacting acetone cyanohydrin (ACH) and sulfuric acid in a second reaction stage (amidation), and heating the second reaction mixture in a third reaction stage (conversion), such that methacrylamide (MAA) is obtained. The process further involves hydrolyzing or esterifying methacrylamide (MAA) with water and, optionally, alcohol, preferably water and optionally methanol, in a fourth reaction stage such that methacrylic acid or alkyl methacrylate is formed. The sulfuric acid used has a concentration of 98.0 wt % to 100.0 wt %.Type: ApplicationFiled: October 19, 2021Publication date: January 11, 2024Applicant: Röhm GmbHInventors: Steffen Krill, Florian Klasovsky, Daniel Helmut König, Patrick Wings
