Thermal Decomposition Of Chlorobenzene Reaction With Hydrogen And Oxygen Mixture In An Atmosphere, Chun-Chen Yang

Theses

The thermal reactions of chlorobenzene in hydrogen and oxygen mixtures were studied in tubular flow reactors at 1 atmosphere total pressure. Experiments were carried out in flow reactors of varied diameter for determining effects of different surface to volume ratios. Residence times ranged from 0.03 to 2.5 seconds and temperature was varied over a range of 560 - 660 °C. The 02/H2 ratios ranged from 1% to 5%.

It was found that the conversion of chlorobenzene in hydrogen and oxygen mixtures increased with both temperature and residence time. The oxidation of chlorobenzene also occurred more rapidly when oxygen concentraction was …

Formation Of Light Hydrocarbons And Soot In The Pyrolysis Reactions Of Chloro, Dichlorobenzene, Acetylene And Benzene In An Atmosphere Of Hydrogen, Larry Jiyuan Zhu

Theses

The kinetics of thermal decomposition of chlorobenzene and dichlorobenzene in a hydrogen and helium atmosphere were further studied to investigate formation of soot and light hydrocarbons. The experiments were performed at atmosphere pressure with residence times rangeing from 0.2 to 1.2 seconds, and the temperature ranges of 850°C to 925°C for chlorobenzene and 870°C to 910°C for dichlorobenzene. Flame ionization detectors, which were connected to GC columns, were utilized for the qualitative and quantitative analysis of the reaction products. A methyl silicone capillary column was used analyzing of heavy aromatics and a Carbosive G was used to analyze light hydrocarbons. …

Thermal Decomposition Of Chlorobenzene In An Atmosphere Of Hydrogen, Edward Robert Ritter

Theses

The thermal decomposition of chlozobenzene was investigated in a tubular flow reactor at 1 atmosphere total pressure and average residence times of 0.02 - 2.5 seconds. The temperature range from 800 - 1010°C was studied in both a reductive atmosphere of hydrogen and an inert atmosphere of heIium. Complete destruction of chlorobenzene occurs at about 1000°C for an average residence time of 1 second in hydrogen gas. In the inert gas, the complete destruction of the reagent was not observed in the range of conditions which were studied. The major products observed for pyrolysis in hydrogen were benzene, HCl, and …

The Photolysis Of Chlorobenzene In An Aqueous Environment, Louis John Del Tufo

Theses

Chlorobenzene was chosen as a model system for the study of photochemically induced reactions in an aqueous environment. It was the goal of this research to achieve a reaction system which best approximates conditions existing in the environment. To do this, a basic model system was established, and then the effect on the rate by various parameters was studied. These parameters, which included the presence of oxygen and such inorganic compounds as might be present in receiving waters, (e.g. nitrate, sulfate, and phosphate), were chosen so as to meet the goal of this research.

Kinetic data was obtained for seven …
