Usage

General Description

Carbonic acid, also known as acid of air or aerial acid, is a weak acid that can be formed by dissolving carbon dioxide in water. It is commonly found in fizzy drinks and soda water, and also plays a role in the transport of carbon dioxide in the bloodstream. Esters are organic compounds that are formed by the reaction between acids and alcohols, and can be found in various natural and synthetic substances such as fragrances, flavorings, and plastics. Monoethyl ester, specifically, is an ester that is derived from the reaction between carbonic acid and ethanol. It is used as a solvent in the production of certain pharmaceuticals and as a reagent in organic synthesis.

Basic Hydrolysis of Some Alkyl and Phenyl N-Aryl-N-methylcarbamates.

Rate constants for the basic hydrolysis of methyl, ethyl and phenyl N-aryl-N-methylcarbamates in the presence and absence of micelles of cetyltrimethylammonium bromide are reported.Hammett plots for the methyl aand ethyl carbamates were curved, and this is explained by consideration of the competition between C-N and C-OR bond breaking for decomposition of the tetrahedral intermediate.In one case (p-nitro-substituted), rate-determining formation of the tetrahedral intermediate is suggested, whereas for other compounds rate-determining C-N bond breaking or C-OR bond bre aking is proposed.Micellar catalysis for each of the reactions is reported, and large catalysis (x 50) was observed for compounds where C-N bond breaking was kinetically significant.This is compared with results in the literature for amide and ester hydrolysis.Whereas, for ester hydrolysis, loss of alkoxide ion from the tetrahedral intermediate is favoured over loss of hydroxide ion, in carbamate hydrolysis, loss of hydroxide ions is favoured.A possible reason for this reversal of nucleofugicity of OH- and OR- is proposed.
