Although ester and carboxylic acid are produced from low-grade alkyl alcohol and the reactant which includes the low-grade alkyl alcoholic formation characteristic composition, in vapor phase carbonylation method the useful solid carbonylation catalyst. This catalyst includes the VIIIth family metal and ...
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...

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...
This invention relates to novel carboxylic acid esters represented by the formula (I) below, methods for their production and insecticides containing them as an active ingredient, <CHEM> wherein R<1> represents a hydrogen atom, a fluorine atom or a methyl group; and R<2> represents a C1-5...
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...
CONSTITUTION:(a) A carboxylic acid is reacted with an alcohol in the liquid or vapor phase in the presence of a catalyst or (b) an ester and a carboxylic acid or alcohol are subjected to ester interchange reaction in the liquid or vapor phase in the presence of a catalyst to synthesize...
These agents are widely used for industrial and manufacturing purposes. The structure of phthalic acid is that of a benzene ring with two carboxylic acid moieties attached to the ring, ortho to one another. It is 1, 2-benzenedicarboxylic acid, with the formula C6H4(CO2H)2. Phth...
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:
