Cyclohexanone - an overview | ScienceDirect Topics
In humans, cyclohexanone is metabolized to cyclohexanol, which is conjugated with glucuronic acid and excreted mainly in urine, where very little cyclohexanone or cyclohexanol is found. The metabolism and kinetics of cyclohexanone were studied in a group of volunteers (4 males and 4 females) during and after 8-h inhalation exposures to 101, 207 ...

2010年7月2日 · Cyclohexanone monooxygenase, 60 on the cyclohexane catabolic pathway, is the prototype of a flavin-dependent Baeyer-Villiger oxygenases 61 and is the most extensively studied system. 62–64 This enzyme catalyzes oxygen incorporation into cyclohexanone to …
Cyclohexanone - an overview | ScienceDirect Topics
Cyclohexanone might be excreted in urine due to an increased water solubility. It is stated that cyclohexanone is formed under metabolic conditions associated with a high oxidation rate of fatty acids and weight loss, which is a symptom of advanced cancer ( Liu et al., 2014b ), but it might also be a contaminant derived from intravenous ...
Ammoximation of cyclohexanone to cyclohexanone oxime using …
2016年10月2日 · Usually cyclohexanone oxime is produced from the condensation of cyclohexanone with hydroxylamine salts, using hydroxylamine as nitrogen source. The conventional technology of oxime production is multi-step, environmentally unfavorable and produces ammonium sulfate as by-product, which causes disposal problem ( Anilkumar and …
Selective photocatalytic oxidation of cyclohexanol to …
2020年2月15日 · A mechanism was proposed for the formation of cyclohexanone and a kinetic model was developed to predict the rate of cyclohexanone production as a function of light intensity and time. The photocatalytic experiments were performed according to a three-level full factorial design, which permitted (i) the calculation of kinetic parameters based ...
Selective hydrogenation of phenol for cyclohexanone: A review
2021年2月25日 · Cyclohexanone (C 6 H 10 O) is an important intermediate for syntheses of nylon6, nylon66, and oxalic acid [1] besides serving as an organic solvent. Currently, the majority of industrial C 6 H 10 O is overwhelmingly synthesized from benzene, with phenol the other minor choice. The benzene routine falls into complete and partial hydrogenation ...
Catalytic approaches for the selective preparation of …
2021年1月1日 · Cyclohexanone is the key intermediate for the preparation of Nylons, lacquers, metal polishing agents, pharmaceutical drugs, herbicides & insecticides and so on. In general, cyclohexanone prepared from petro-derived feedstock such as selective oxidation of cyclohexane and selective hydrogenation of phenol.
Selective oxidation of cyclohexanol to cyclohexanone with ...
2024年9月25日 · Cyclohexanone is an organic compound that contains a ketone functional group. It is widely used as a precursor for the production of nylons and as a solvent for resins and paints [1] , [2] . The existing commercial processes for cyclohexanone production involve the oxidation of cyclohexane or cyclohexanol, as well as the hydrogenation of phenol ...

Distribution of cyclohexanol and cyclohexanone between water …
2015年5月25日 · Liquid–liquid equilibrium (LLE) data for ternary systems water + cyclohexane + cyclohexanol and water + cyclohexane + cyclohexanone were measured at (303.2–333.2) K and under atmospheric pressure. The reliability of the experimental tie-line data was checked by the empirical Othmer–Tobias correlation. The distribution coefficient and ...
