Cyclohexene is produced by the partial hydrogenation of benzene, a process developed by the Asahi Chemical company. [4] The main product of the process is cyclohexane because cyclohexene is more easily hydrogenated than benzene. In the laboratory, it can be prepared by dehydration of cyclohexanol. [5] C 6 H 11 OH → C 6 H 10 + H 2 O
Aromatization. Aromatization is a chemical reaction in which an aromatic system is formed from a single nonaromatic precursor. Typically aromatization is achieved by dehydrogenation of existing cyclic compounds, illustrated by the conversion of cyclohexane into benzene. Aromatization includes the formation of heterocyclic systems.
Starch gelatinization. Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves the starch granule in water. Water acts as a plasticizer.
Cyclohexanone is produced by the oxidation of cyclohexane in air, typically using cobalt catalysts: [11]. C 6 H 12 + O 2 → (CH 2) 5 CO + H 2 O. This process forms cyclohexanol as a by-product, and this mixture, called "KA Oil" for ketone-alcohol oil, is the main feedstock for the production of adipic acid.
A solvent (from the Latin solvÅ, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules, and the most common solvent used by living things; all the ions and proteins in a cell are ...
Cyclohexylamine is used as an intermediate in synthesis of other organic compounds. It is the precursor to sulfenamide -based reagents used as accelerators for vulcanization. The amine itself is an effective corrosion inhibitor. It has been used as a flushing aid in the printing ink industry. [5]
An "improvised explosive device” rocked the California courthouse where Michael Jackson was tried and acquitted nearly 20 years ago, authorities said. Residents near the court in Santa Maria ...
Strengthening mechanisms of materials. Methods have been devised to modify the yield strength, ductility, and toughness of both crystalline and amorphous materials. These strengthening mechanisms give engineers the ability to tailor the mechanical properties of materials to suit a variety of different applications.
