The Monsanto process is an industrial method for the manufacture of acetic acid by catalytic carbonylation of methanol. [1] The Monsanto process has largely been supplanted by the Cativa process, a similar iridium-based process developed by BP Chemicals Ltd, which is more economical and environmentally friendly.
Thioacetic acid is an organosulfur compound with the molecular formula CH 3 C(O)SH. It is a thioic acid: the sulfur analogue of acetic acid (CH 3 C(O)OH), as implied by the thio-prefix. It is a yellow liquid with a strong thiol-like odor. It is used in organic synthesis for the introduction of thiol groups (−SH) in molecules. [4]
acetyl chloride SOCl 2 acetic acid (i) Li[AlH 4], ether (ii) H 3 O + ethanol Two typical organic reactions of acetic acid Acetic acid undergoes the typical chemical reactions of a carboxylic acid. Upon treatment with a standard base, it converts to metal acetate and water. With strong bases (e.g., organolithium reagents), it can be doubly deprotonated to give LiCH 2 COOLi. Reduction of acetic ...
The mechanism of the Pummerer rearrangement begins with the acylation of the sulfoxide (resonance structures 1 and 2) by acetic anhydride to give 3, with acetate as byproduct. . The acetate then acts as a catalyst to induce an elimination reaction to produce the cationic-thial structure 4, with acetic acid as byprod
Dissolving Knorr's pyrrole in concentrated sulfuric acid, and then pouring the resulting solution into water will hydrolyze the 4-ester group selectively. The 5-methyl group can be variously oxidized to chloromethyl, aldehyde, or carboxylic acid functionality by the use of stoichiometric sulfuryl chloride in glacial acetic acid. [7]
Tetrahydropyran (THP) is the organic compound consisting of a saturated six-membered ring containing five carbon atoms and one oxygen atom. It is named by reference to pyran, which contains two double bonds, and may be produced from it by adding four hydrogens.
MPAA (4-Mercaptophenylacetic acid) is a redox buffer that increases the folding rate of disulfide-containing proteins. MPAA is also used in native chemical ligation as a thiol catalyst . This article about an organic compound is a stub .
Methyl phenylacetate is an organic compound that is the methyl ester of phenylacetic acid, with the structural formula . It is a colorless liquid that is only slightly soluble in water, but soluble in most organic solvents. Methyl phenylacetate has a strong odor similar to honey.
