Ethenone is produced by thermal dehydration of acetic acid at 700–750 °C in the presence of triethyl phosphate as a catalyst: [7] [8] CH 3 CO 2 H → CH 2 =C=O + H 2 O. It has also been produced on a laboratory scale by the thermolysis of acetone at 600–700 °C. [9] [10] CH 3 COCH 3 →CH 2 =C=O + CH 4. This reaction is called the ...
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.
3,4-Epoxycyclohexylmethyl-3',4'-epoxycyclohexane carboxylate (ECC) is a cycloaliphatic epoxy resin which is used in many industrial applications. It reacts by cationic polymerization using thermolatent photoinitiators to form crosslinked insoluble thermosets.
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]
116.22 g·mol −1 Appearance Colorless liquid Density: 0.95 g/cm 3: Boiling point: 158 to 160 °C (316 to 320 °F; 431 to 433 K) Solubility in water. Low
The density is 882.73 kgm −1. The isothermal compressibility is 674 TPa −1 and isobaric expansivity is 819 K −1. [5] When bicyclohexyl is heated to around 427 °C (801 °F) it slowly decomposes to cyclohexane and cyclohexene, as the pivot bond joining the two rings is the longest and weakest one. [6] Heat of combustion is 1814.8 kcal/mol. [7]
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.
A mixture of cis-decalin and CXB can simultaneously match optical index and density of PMMA. [1] Due to the moderate dielectric constant of CXB (ε = 7.9 [ 2 ] ), PMMA acquires charges that can be screened by the addition of salt (e.g. tetrabutyl ammonium bromide ), leading to a very good approximation of colloidal hard sphere .
