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...
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...
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....

< 0045 >It is the ester of aliphatic or aromatic mono acid, new fat poripuropokishiretoesuteru which is formed by reacting the said acid with the stoichiometry excessive poripuropokishiru conversion fatty alcohol. Particular chemical compound has structural formula (i) below. In formula, R is...
This study is devoted to a new surface treatment of zinc, called "carboxylating", which could be an environmentally friendly alternative to the usual conversion treatments. Carboxylating requires use of both n-alkyl carboxylic acid and peroxoborate as oxidizing agent, in a water–ethanol mixture....
