Kinetics and mechanism of electrophilic bromination of acetylenes
The rates of addition of molecular bromine in acetic acid to a number of acetylenes have been found to follow the general equation d(Br,)/dt = [acetylene](k, [Br,] + k3 [Br212 + k,,[Br,] [Br1) In the absence of bromide ion and at low bromine concentrations (< 2 x M), only the k 2 process is observable. These k 2 values for a series of ring-substituted phenylacetylenes are correlated well with o...
متن کاملElectrophilic Aromatic Substitution of Catechins: Bromination and Benzylation
Relative yields of C-6, C-8. and C-6 and C-8 substituted catechins obtained from the reaction of (+ )-catechin or 3' 4',57-tetra-O-methvl-( + )-catechin with pyridinium hydrobromide-perbromide, bromine. p-hydroxybenzyl al~oh~I, or o-hydroxybenZyI alcohol showed differing selectivities depending upon the electrophile used. Ratios of C-6 to C-8 substituted products were 1 : 1.2 for the reaction o...
متن کاملAcid Catalysed Condesation of Phloroglucinol and Acetone-Kinetics and Mechanism
The kinetic study of the condensation reaction between phloroglucinol and acetone was investigated at 30, 35, 40 and 45±0.05 °C in 100% methanol. The hydrochloric acid concentrations used were 0.0261, 0.0364, 0.0577 and 0.0728 M. The reaction was investigated with and without a promoter, thioglycollic acid (TGA), and taking into account the functionality (h<e...

15 صفحه اولThe Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
