, p. 587 - 595 (2019/06/24)
Abstract: The buildup kinetics of the main and side products during uncatalyzed and cobalt naphthenate-catalyzed oxidation of cyclohexane at 150°C have been studied. 6-Hydroxyhexanoic, 6-oxohexanoic, and adipic acids are accumulated in parallel during the oxidation of cyclohexane, cyclohexanone, and 2-hydroxycyclohexanone. The critical consideration of their known formation pathways and the reactivity of possible precursors gives evidence for the predominant formation of 6-hydroxyhexanoic acid at the step of cyclohexanol oxidation and adipic acid from 2-hydroxycyclohexanol.

Breaking the rules: Reversal of the high Markovnikov selectivity of Wacker-type oxidations was accomplished using a nitrite co-catalyst. Unbiased aliphatic alkenes can be oxidized with high yield and aldehyde selectivity, and several functional groups are tolerated. 18O-labeling experiments indicate that the aldehydic O atom is derived from the nitrite salt.

METHOD FOR PRODUCING OXYGEN-CONTAINING COMPOUND

Page/Page column 23, (2012/01/11)
[Problem] There is provided a method for producing an oxygen-containing compound safely and with improved reaction efficiency, in which an undesired peroxide is unlikely to be produced, and efficient heat exchange of the ozonization can be achieved. [Mean for solving the Problem] The method comprises an ozonization reaction step of continuously supplying, together with an organic compound, ozone having an oxygen content of less than 10% in a dissolved state in high-pressure carbon dioxide to an ozonization reaction section having a thin tubular shape, and reacting the ozone and the organic compound under conditions that suppress generation of oxygen due to thermal decomposition of the ozone, thereby continuously producing an ozonide; and a decomposition reaction step of continuously supplying the ozonide produced in the ozonization reaction step to a decomposition reaction section having a thin tubular shape, thereby continuously producing an oxygen-containing compound, the decomposition reaction step being provided in a manner continuous with the ozonization reaction step.
