Atmospheric photochemical oxidation of 1-octene: OH, O3 and O(3P) reactions

Article Abstract:

1-Octene is a man-made contributor to the formation of photochemical smog, and its photoxidation chemistry is examined in detail. Experiments in a flexible outdoor smog chamber indicated that the O(3P) reaction is similar to that of smaller alkenes such as 1-hexene, 1-nonene and 2-ethyl-1-hexene, but the OH alkoxy radical reaction and the O3 proceed differently than the smaller hydrocarbons.

Hydrocarbon formation in metallic iron/water systems

Article Abstract:

The Fischer-Tropsch synthesis of hydrocarbons is proposed to explain the production of non-chlorinated hydrocarbons from the interaction of chlorinated ethylenes with iron in the iron/water system of groundwater remediation. Carbide is the main source of carbon for the background hydrocarbons of the process. The carbon in the carbide is released via acid dissolution.

Formation of 2-hydroxyethyl hydroperoxide in an OH-initiated reaction of ethylene in air in the absence of NO

Article Abstract:

The formation of 2-hydroxyethyl hydroperoxide (HOCH2CH2OOH) as a result of reactions between airborne OH and ethylene is investigated. The results indicated that HO2 radicals are abundant in the reaction system because of OH-H2O reactions. However, more research is needed to obtain direct evidence of hydroperoxide formation in OH-alkene reactions.
