  • Publication number: 20180237372
    Abstract: A method for preparing acrylic acid, more specifically, to a method for preparing acrylic acid under a neutral condition at high yield in a short time without using a base, unlike the prior art in which a base is essentially used. The acrylic acid is produced using a supported catalyst having a specific composition when preparing acrylic acid by oxidation of allyl alcohol. Particularly, the preparation method can recover acrylic acid rather than acrylic acid salt as a final product, and thus has an advantage that the overall process cost can be reduced by eliminating essential processes in the prior art, such as ion exchange after the acidification process required for the conversion of acrylic acid salt to acrylic acid.

  • Publication number: 20180118772
    Abstract: Disclosed is a novel catalyst having amine ligands for synthesizing methanol or its precursor. When the catalyst is allowed to react with an alkane in the presence of an acid, at least one C—H bond of the alkane is catalytically oxidized. Therefore, the catalyst is suitable for use in forming an alkyl ester from an alkane.

  • Publication number: 20180111918
    Abstract: The present invention provides a diaminopyrimidine derivative or its pharmaceutically acceptable salt, a process for the preparation thereof, a pharmaceutical composition comprising the same, and a use thereof. The diaminopyrimidine derivative or its pharmaceutically acceptable salt functions as a 5-HT4 receptor agonist, and therefore can be usefully applied for preventing or treating dysfunction in gastrointestinal motility, one of the gastrointestinal diseases, such as gastroesophageal reflux disease (GERD), constipation, irritable bowel syndrome (IBS), dyspepsia, post-operative ileus, delayed gastric emptying, gastroparesis, intestinal pseudo-obstruction, drug-induced delayed transit, or diabetic gastric atony.

  • Publication number: 20180029959
    Abstract: Disclosed is a Lewis acid catalyst for preparation of toluene from 2-methylfuran and a method for preparing toluene from 2-methylfuran by using the same. The catalyst is a zeolite catalyst ion-exchanged with a metal or a metal halide catalyst. The catalyst accelerates the cycloaddition of 2-methylfuran with ethylene and inhibits oligomerization as a side reaction, and thus allows production of toluene from 2-methylfuran with high yield and high selectivity.
