Effect of cyclohexanol on phase stability and volatility behavior of hydrous ethanol-gasoline blends

Egyptian Journal of Petroleum, 2021
Biofuels can contribute to reducing greenhouse gas emissions and bridging the gap between production and consumption. Ethanol is a renewable source of energy. It can reduce oil dependence and also can be appropriately used in gasoline as a blend.

Reactive Distillation for the Production of Cyclohexanol: Experiments and Simulations [PDF]

Chemical and Biochemical Engineering Quarterly, 2021
Cyclohexanol is an organic chemical intermediate product widely used in chemical industry and commonly produced by cyclohexene hydration. Because of the low mutual solubility of cyclohexene and water, the reaction is limited by chemical equilibrium ...

In Situ Hydrodeoxygenation of Lignin-Derived Phenols With Synergistic Effect Between the Bimetal and Nb2O5 Support

Frontiers in Energy Research, 2021
Nb2O5-supported bimetallic catalysts were prepared by the impregnation method applied for the in situ hydrogenation of guaiacol. Guaiacol can be effectively transformed into cyclohexanol over different bimetallic catalysts using alcohol as the hydrogen ...

Results of GC-MS Analyses of 40 Extracts of Diabetes Devices. [PDF]

Contact Dermatitis
Forty acetone extracts of 27 diabetes devices were investigated by gas chromatography–mass spectrometry. Two hundred eighty four individual chemicals were identified. All 40 extracts contained one or more chemicals that were previously identified as allergens in diabetes devices causing allergic Contact Dermatitis.
