In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. 99-10-5, Name is 3,5-Dihydroxybenzoic acid, molecular formurla is C7H6O4. In a document, author is Peter, A, introducing its new discovery. Quality Control of 3,5-Dihydroxybenzoic acid.
Application of a new chiral derivatizing agent to the enantioseparation of secondary amino acids
A new chiral derivatizing, agent, (S)-N-(4-nitrophenoxycarbonyl)phenylalanine methoxyethyl ester, (S)-NIFE, was applied for the high-performance liquid chromatographic separation of enantiomers of 19 unnatural secondary amino acids: proline, pipecolic acid analogues, piperazine-2-carboxylic acid, morpholine-3-carboxylic acid, thiomorpholine-3-carboxylic acid and analogues containing the 1,2,3,4-tetrahydroisoquinoline, 1,2,3,4-tetrahydronorharmane, 1,2,3,4-tetrahydro-2-carboline and 2-benzazepine skeletons. Excellent resolutions were achieved for most of the investigated compounds by using a reversed-phase mobile phase system. The conditions of separation were optimized by variation of the mobile phase composition. (C) 2002 Elsevier Science B.V. All rights reserved.
Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst, therefore, does not appear in the overall stoichiometry of the reaction it catalyzes.I hope my blog about 99-10-5 is helpful to your research.
