Esters derived from carboxylic acids are the most common. The term ester was introduced in the first half of the 19th century by German chemist Leopold Gmelin. Carboxylic acid esters, formula RCOOR′ (R and R′ are any organic combining groups), are commonly prepared by reaction of carboxylic...
From - di-carboxylic acid ester and olefin Characteristic unsaturated chemical compound production manner null of the constituent and the said constituent whichPURPOSE: To prepare a composition that has a low pour-point and is suitable for lubricants (additives) by incorporating therein a medium-...
The invention relates to novel carboxylic-acid-ester-type tetraalkyl ammonium salts, the production thereof and the pharmaceutical use thereof in fungal and bacterial infections and as potential inhibitors in the biosynthesis of cholesterol. The compounds, which are produced by reacting aliphatic or phen...
A process for poly(ester-carbonates) from dihydric phenols, especially bisphenol A; aromatic or cycloaliphatic dicarboxylic acids, especially terephthalic acid; and phosgene as carbonate precursor wherein a reaction of the acid and phosgene is carried out in a first stage forming dicarboxylic acid chl...
The present invention relates to resin compositions comprising a mixture of at least two resins, one resin consisting of the reaction product of an epoxidized fatty acid ester of a polyvalent alcohol with a carboxylic acid, and another resin consisting of a carboxylic acid-modified ester of a pol...
Good yields of 1:1 adducts have also been obtained from Lewis acid catalyzed reactions of methyl chloropropiolate or DMAD with alkenes.61–64With methyl chloropropiolate, cyclobutenes are obtained exclusively from mono- and 1,2-di-substituted alkenes and mixtures of ene adducts ...
4,5-Diphenyl oxazoles (76)297may be prepared from carboxylic acids andbenzoinby esterification, followed by treatment withammonium acetatein glacial acetic acid in overall yields of 80–85% (Scheme 75). Theheterocyclesthus obtained can be functionalized in numerous ways (alkylations, Friedel- Craft...
On the other hand, DMF efficacy was diminished in EAE-induced mice lacking hydroxycarboxylic acid receptor 2 (HCA2/GPR109A) which belong to the G protein-coupled receptor (GPCR) family (Chen et al., 2014), indicating an Nrf2-independent MOA of DMF. This is supported by the fin...
This invention relates to a novel carboxylic acid ester represented by the following general formula (I) and an insecticidal and/or acaricidal composition containing the same as an active ingredient:
Acid dyes derived from aminobenzene dicarboxylic acid esters and 1-hydroxy-7-amino-naphthalene-3-sulfonic acid, particularly for dyeing wool or textile material of synthetic linear polyamides. Inventors: Dehnert, Johannes (Ludwigshafen, DT) Gnad, Gerhard (Ludwigshafen, DT) ...
