- Cyclohexanone - an overview | ScienceDirect Topics
Cyclohexanone oxime is the intermediate used to produce caprolactam, of which 90% is obtained by the rearrangement of cyclohexanone oxime A novel method of catalytic direct ammoxidation of cyclohexanone with NH 3 H 2 O 2 to the oxime using TS-1 as the catalyst was developed
- Selective hydrogenation of phenol for cyclohexanone: A review
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
- Sustainable production of cyclohexanones through hydrodeoxygenation of . . .
The selectivity towards cyclohexanone and its derivatives remained as high as 38 57%, 57 48%, 29 21%, and 37 40%, respectively (Entry 2–5 in Table 1) Based on GC–MS data (see Supplementary Materials ), it was evident that cyclohexanones remained the predominant products, highlighting the robust demethoxylation ability of the PdFe system
- Catalytic approaches for the selective preparation of cyclohexanone . . .
The concentration of H 2 produced from HCOONa was lower and is sufficient for phenol to cyclohexanone via intermediate of 1-hydroxycyclohexene and this low H 2 is not favorable for either 1-hydroxycyclohexene intermediate or cyclohexanone (formed in the reaction) conversion to cyclohexanol (Scheme 14–8) Thus, cyclohexanone product is

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
- Biosynthesis of cyclic ketones by a H2O2 self-sufficient cascade . . .
After 4 h of reaction, the concentration of cyclohexanol remained basically unchanged, while the concentration of cyclohexanone was still increasing slowly We assume that in this phase both reactions (AaeUPO-catalysed hydroxylation and PcAOx-EFMH-catalysed formation of cyclohexanone) proceeded at the same rates Finally, after 12 h of reaction
- Curved plane increases the d vacancy population of Pd for green . . .
Cyclohexanone is a crucial raw material for the production of ε-caprolactam and adipic acid (over 90% from the oxidation of cyclohexanol), which are, respectively, key intermediates for the production of nylon-6 and nylon-66 1 The selective hydrogenation of phenol is increasingly used as a commercial route for the production of cyclohexanone because it is easier than the oxidation of
- Self-polymerization reaction of cyclohexanone: Kinetics and . . .
The reported conversion of cyclohexanone was around 30% with a yield of around 95% towards 2-(1-cyclohexenyl) cyclohexanone Jose et al [9] have studied the kinetics of self–condensation of cyclohexanone at a temperature range of 70–110 °C in the presence of Amberlyst-15 as a catalyst In the study, a mixture of dimer and trimer products
