The process includes the use of a modified base-exchanged niobium catalyst that is particularly useful for the production of cyclopropyl ketones such as cyclopropyl methyl ketone from cyclopropanecarboxylic acid and acetic acid.Joseph Robert Zoeller...
The proposed method allows a simple homologation of ... S. Xue - 《Synfacts》 被引量: 1发表: 2005年 Zinc-mediated conversion of b-keto esters to y-keto esters. Assesses three methods which were used for the formation and fragmentation of 2-carboxycyclopropy alcohols from ketone esters. ...
摘要: A new and efficient procedure for the transformation of α-diazo-β-hydroxy esters into the corresponding β-keto esters, which involves the use of Rh2(OAc)4, is described.关键词: carboxylic acid esters (acyclic compounds DOI: 10.1039/C39790000959 被引量: 27 ...
The conversion of methanol over zeolites offers a sustainable alternative for fuels and chemicals production. However, a complete understanding of the competing reaction pathways, particularly those leading to C-C bond formation, remains elusive. This wo
(57)< Abstract > Being revised manner of the oxime conversion ketone and aldehyde etc due to the oxime conversion of the hydroxylamine of the carbonyl compound, under phase change catalytic converter existing of the catalytic converter tonnage which includes the blend of the organicity carboxylic a...
Exploring approaches to utilize abundant water to synthesize functional molecules and polymers with efficient clusteroluminescence properties is highly significant but has yet to be reported. Herein, a chemistry of water and alkyne is developed. The synt
Subsequent conversion of some anti oxime back to syn under strip conditions was also observed. Introduction Recent work has raised interest in the use of a synergistic solvent extraction system containing LIX®63 (an aliphatic α-hydroxyoxime) and Versatic 10 (a carboxylic acid) as this reagent...
14. A method as define in claim 1 wherein said oil soluble transition metal compound comprises a transition metal compound selected form the group consisting of organic carboxylic acid compounds, organic alkoxy compounds, diketone compounds, carbonyl compounds, organic sulfonic acid or organic sulfinic...
This invention provides a method for thermally converting volatile fatty acid (VFA) salts to ketones by mixing dry calcium salts of VFAs with hot heat transfer agent in an evacuated container, thereby causing thermal decomposition of the calcium salts of VFAs to form ketone-containing vapor and ca...
50.An integrated process for making one or more olefin(s), the integrated process comprising the steps of:(a) passing a hydrocarbon feedstock to a syngas production zone to producing a synthesis gas stream;(b) contacting the synthesis gas stream with a catalyst to form an oxygenated feedstock...
