Kinetic Investigation Of The Hydrochlorination Of Olefins In Aprotic Solvents And Sulfonation Of Idobenzene And The Selectivity Relation, Thomas Glen Davies
Kinetic Investigation Of The Hydrochlorination Of Olefins In Aprotic Solvents And Sulfonation Of Idobenzene And The Selectivity Relation, Thomas Glen Davies
Theses and Dissertations
Kinetic investigation of the hydrochlorination of cyclohexene and cis-2-butene in n-heptane with SnCl4 as catalyst shows that the reaction is second order with respect to both olefin and catalyst. The specific rate constants at 25° , 0° and -23.8°C and the activation parameters were determined. Investigation of the Ga2Cl6 catalyzed hydrochlorination of cyclohexene and cis-2-butene in dichloromethane indicates that alkylation and polymerization compete with the hydrochlorination reaction in the presence of the solvent. The relative reaction rates and the isomer distribution for the sulfonation of iodobenzene by S35O3 have been determined in refluxing SO2 at -10°C. The reaction resulted in …
Sulfonation Of Chlorobenzene And The Selectivity Relation ; Bromine Addition To Cyclohexene In Dichloromethane ; Thorpe's Synthesis Of The Caged Acid, 4-Methyltricyclo[1.1.0.0[Superscript 2-4]] Butane-1,2,3-Tricarboxylic Acid, John A. Gurney

Aromatic sulfonation and some substitution reactions of chlorobenzene show deviations in the selectivity relation. A determination of chlorobenzene sulfonation provided the following rate ratio relative to benzene and partial rate factors: 1.0, [---] of 0.064 , mf 1.7 and pf 4. 2. Our work, Olah's nitration, Ferguson's bromination and Stock's chlorination define a new relation that can be express by adding an entropy term (A) to the selectivity relation. We determined the rate of bromine-cyclohexene addition in dichloro-methane at 0° to provide a basis for a systematic variation of solvents at low temperature. An unusual zero-order reaction was encountered. The …

Part Iii., Preliminary Survey On The Effect Of High Pressure On Ferrocene And Cycloöctatetraene, Jerold Carter Robertson

Part I. The rearrangement of α-anilinoketones was studied in an effort to determine the mode of movement of the nitrogen moiety. A crossover experiment was carried out with an equimolar mixture of 2-(4- bromoanilino)-1-(4-bromophenyl)-2-(4-methoxyphenyl) ethanone and 2-(4-chloroanilino)-1-(4-chlorophenyl) -2-(4-methoxyphenyl)ethanone with γ- picoline hydrobromide as the catalyst. The reaction product was analysed by means of a mass spectrograph. The results of the analysis indicate a crossover of the nitrogen moiety during rearrangement. This indicates that the nitrogen moiety moves in an intermolecular manner during the rearrangement. Part II. The isomer distribution from the sulfonation of bromobenzene with sulfur trioxide was determined by …
