A process for converting formic acid esters or transesterification products thereof to carboxylic acids comprising contacting a formic acid ester of the formula (HCOO).sub.n --R where R is aliphatic, cycloaliphatic or aralkyl and n is 1 or 2 with a catalytically effective amount of a soluble...
I am going to write my extended essay on chemistry, and I came up with a topic which is “what is the effect of different concentrations of sulfuric acid as a catalyst of esterification on the yield of ester when ethanol is reacted with ethanoic acid”, but my...
The present invention relates to processes for the production of a calcium carboxylate directly from an ester or anhydride. BACKGROUND OF THE INVENTION Calcium carboxylates are useful in the production of the corresponding carboxylic acids. Calcium carboxylates also have other beneficial applications. Fo...
Reactions of acetaldehyde on UO2(111) single crystal surfaces. Evidence of benzene formation (forming alkoxides and carboxylates) and Tishchenko (forming ester) have been observed on various metal oxide surfaces, in addition to direct oxidation and... S. V. Chong,H Idriss - 《Journal of Vacu...
This approach not only represents a convenient and economic approach to a direct transformation of an alkoxyamide moiety into the carboxylic ester functional group, via oxidative homocoupling and the subsequent thermal denitrogenation, but also facilitates the synthesis of sterically hindered carboxylic ...
This review summarizes the recent progress of RE(OTf)(3) catalyzed organic synthesis in green media including water, ionic liquids, super critical CO2, solvent-free conditions as well as solid supported synthesis.关键词: amide formation carboxylic amides (acyclic compounds carboxylic amides (benzene ...
carboxylic acid esters (acyclic compoundsWe were the first to observe the intramolecular cyclization of alkoxycarbonylcarbenes under the conditions for the thermal decomposition of alkyl diazoacetates, which proceeds via the insertion of the carbene C atom in theß-C -H bond of the ester group....
The -ketoacid (ester) system is a useful synthon leading to 1,4-diketones and other important intermediates in organic synthesis. Two well established routes to these compounds which consist of (1) alkylation of -ketoesters with haloacet... Ho,Tse-Lok - 《Synthetic Communications》 被引量: ...
ChemInform Abstract: Conversion of 1‐Benzyl‐4‐aminotetrahydropyridine‐3‐carboxylic Acid Methyl Ester to Antithrombotic Pyrido(4,3‐d)pyrimidine‐2,4‐diones and to (2‐Oxotetrahydropyrimidin‐4‐ylidene)acetic Acid Methyl Estersfused pyrimidine derivatives...
And saccharification of biomass is fermented in two steps, to produce two separate products. The second product is a carboxylic acid, which is reacted with an alcohol to produce an ester. Alcohol used for the esterification, may be obtained from biomass. Ester is hydrogenated to an alcohol ...
