Bisphenol A is difunctional and used to produce epoxy resin and polycarbonate. 4-tert-Butylphenol is monofunctional and so in polymer science terms, bisphenol A is a polymer chain extender but 4-tert-butylphenol is a chain stopper or sometimes called endcapper. It is thus use to control molecular weight by limiting chain growth.
Cyclohexanol is produced by the oxidation of cyclohexane in air, typically using cobalt catalysts: [5]. 2 C 6 H 12 + O 2 → 2 C 6 H 11 OH. This process coforms cyclohexanone, and this mixture ("KA oil" for ketone-alcohol oil) is the main feedstock for the production of adipic acid.
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:

Cyclohexane chair flip (ring inversion) reaction via boat conformation 4. Structures of the significant conformations are shown: chair 1 , half-chair 2 , twist-boat 3 and boat 4 . When ring flip happens completely from chair to chair, hydrogens that were previously axial ( blue H in upper-left structure) turn equatorial and equatorial ones ...
The cis/trans ratio of the CHDM is affected by the catalyst. [2] Byproduct of this process are 4-methylcyclohexanemethanol (CH 3 C 6 H 10 CH 2 OH) and the monoester methyl 4-methyl-4-cyclohexanecarboxylate (CH 3 C 6 H 10 CO 2 CH 3, CAS registry number 51181-40-9). [3] The leading producers in CHDM are Eastman Chemical in US and SK Chemicals in ...
