Adsorption kinetics of 2-chloroacétophénone and 4-bromoacétophénone thiosemicarbazone on Oueme Valley clays (R. Benin)

2-chloroacetophenone-thiosemicarbazone and 4-bromoacétophénone-thiosemicarbazone are compounds endowed with numerous pharmacological properties.  In order to produce therapeutic agents using clay as excipient, this paper deals with the absorption kinetics of a clay originating from Oueme valley in Benin. A prospection in this area gave rise to the collection of 4 samples classified according to their...

Substituent effects of 2-aryl-trans-decahydroquinolin-4-ones in CTADC oxidation: Spectrophotometric approach

A kinetic study was carried out using spectrophotometric approach on the oxidation of nine differently substituted 2-aryl-trans-decahydroquinolin-4-ones by Cetyltrimethylammonium dichromate (CTADC) as oxidant at 30°C and in aqueous acetic acid (50%) containing catalytic amount of sulphuric acid (6N). The reactions were studied at 350 nm. The reaction was found to follow second order kinetics. The substitution of...

Kinetics of the corrosion of mild steel in petroleum-water mixture using ethyl ester of lard as inhibitor

Ethyl Esters of Pork Oil (EEL) has been investigated as a mild steel corrosion inhibitor in petroleum-water mixture by weight-loss tests at different concentrations (0.1l, 0.2, 0.3, 0.4 and 0.5g/L) of inhibitor, and at temperatures of 303, 313, 323 and 333K. Results show that inhibition efficiency increases as the inhibitor concentration increases, decreases with temperature, and follows the Langmuir adsorption...
