Ethenone is a highly reactive gas (at standard conditions) and has a sharp irritating odour.It is only reasonably stable at low temperatures (−80 °C). It must therefore always be prepared for each use and processed immediately, otherwise a dimerization to diketene occurs or it reacts to polymers that are difficult to handle.
Cyclohexenone is an organic compound which is a versatile intermediate used in the synthesis of a variety of chemical products such as pharmaceuticals and fragrances. [2] It is colorless liquid, but commercial samples are often yellow.
It was first prepared by the free-radical reaction of cyclohexane using carbon disulfide as a sulfur source. [1] It is produced industrially by the hydrogenation of cyclohexanone in the presence of hydrogen sulfide over a metal sulfide catalyst: C 6 H 10 O + H 2 S + H 2 → C 6 H 11 SH + H 2 O
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.
Cyclohexylmethanol is an organic compound with the formula C 6 H 11 −CH 2 −OH. It is a cyclohexane ring functionalized with an alcohol , specifically a hydroxymethyl group. The compound is a colorless liquid, although commercial samples can appear yellow.
They are named analogously to their normal alkane counterpart of the same carbon count: methylcyclopropane, methylcyclobutane, methylcyclopentane, methylcyclohexane, etc. [1] Methylcycloalkanes are classed into compounds with small, normal and bigger cycloalkanes, where cyclopropane and cyclobutane are the small ones, cyclopentane , cyclohexane ...
Bicyclohexyl, also known as dicyclohexyl or bicyclohexane, is an organic chemical with the formula C 12 H 22 and a molecular mass of 166.303 g mol −1. It is a nonvolatile liquid at room temperature, with a boiling point of 227 °C (441 °F). Its structure consists of two cyclohexane rings joined by a single carbon-carbon bond.
1-Ethynylcyclohexanol (ECX) is an alkynyl alcohol derivative which is both a synthetic precursor to, and an active metabolite of the tranquilizer ethinamate, and has similar sedative, anticonvulsant and muscle relaxant effects. It has been sold as a designer drug, first being identified in the UK in March 2012. [1] [2] [3] [4]
