“…Solutia produces 400 000 t/a of adipic acid from cyclohexane [63], which is associated with the formation of about 200 000 t/a of nitrous oxide [59]. Nitrous oxide is a greenhouse gas and must be decomposed to avoid emission [64]. The use of nitrous oxide for the direct oxidation of benzene would therefore be ideally suited to any adipic acid producer.…”

“…The process for producing adipic acid from KA oil via nitric acid oxidation historically produced 400,000 metric tons of N 2 O globally. N 2 O has a global warming potential approximately 300 times that of CO 2 [4]. However, recent catalytic and thermal abatement of these emissions within both adipic acid and nitric acid processes has resulted in very significant reductions in attendant N 2 O emissions, and therefore of their environmental significance.…”

The Low Temperature Solvent-Free Aerobic Oxidation of Cyclohexene to Cyclohexane Diol over Highly Active Au/Graphite and Au/Graphene Catalysts

Abstract:The selectivity and activity of gold-catalysts supported on graphite and graphene have been compared in the oxidation of cyclohexene. These catalysts were prepared via impregnation and sol immobilisation methods, and tested using solventless and radical initiator-free reaction conditions. The selectivity of these catalysts has been directed towards cyclohexene epoxide using WO 3 as a co-catalyst and further to cyclohexane diol by the addition of water, achieving a maximum selectivity of 17% to the diol. The sol immobilisation catalysts were more reproducible and far more active, however, selectivity towards the diol was lower than for the impregnation catalyst. The results suggest that formation of cyclohexane diol through solventless oxidation of cyclohexene is limited by a number of factors, such as the formation of an allylic hydroperoxyl species as well as the amount of in situ generated water.

“…N 2 O is a greenhouse gas for which 5-8% of global emissions can be attributed to adipic acid production. [68] An alternative route to adipic acid is the direct oxidation of cyclohexene over Na 2 WO 2 by 30% H 2 O 2 , using [CH 3 (n-C 8 H 17 ) 3 N]HSO 4 as a phase transfer catalyst. [69] This reaction has a high yield (93%),…”

A View Through Novel Process Windows

et al. 2013

This mini-review discusses some of the recent work on Novel Process Windows by the group of Micro Flow Chemistry and Process Technology at the Eindhoven University of Technology, and their associates. Novel Process Windows consist of unconventional approaches to boost chemical production, often requiring harsh reaction conditions at short to very short time-scales. These approaches are divided into six routes: the use of high temperatures, high pressures, and high concentrations (or solvent-free), new chemical transformations, explosive conditions and process simplification and integration. Microstructured reactors, due to their inherent safety, short timescales and the high degree of process control, are the means that make such extreme chemistry possible.
