4-tert-Butylphenol is an organic compound with the formula (CH3)3CC6H4OH. It is one of three isomeric tert-butyl phenols. It is a white solid with a distinct phenolic odor. It dissolves in basic water. [2]

Contents

Manufacture

It can be prepared by acid-catalyzed alkylation of phenol with isobutene, 2-tert-butylphenol being the major side product. It can be produced by diverse transalkylation reactions.

Uses

It major uses are in the production of epoxy resins and curing agents and also in polycarbonate resins. It has also found use in the production of phenolic resins. Another use is in the production of para tertiary butylphenol formaldehyde resin. It has also found use as a plasticizer.

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.

4-tert-Butylphenol has an OH group and so it may be reacted with epichlorohydrin and sodium hydroxide to produce the glycidyl ether which is used in epoxy resin chemistry. This molecule has the CAS Registry number of 3101-60-8. [3] [4]

Laboratory reactions

Hydrogenation gives trans-4-tert-butylcyclohexanol. [5]

Controlled condensation with formaldehyde gives calixarenes. [6]

Safety

OSHA records show it as an irritant and has developed suggested test methods for its detection. [7] A European Union risk assessment report into the molecule dated May 2006 suggested it had potential depigmenting properties and was a potential endocrine disruptor. This was done under its EINECS number of 202-679-0. [8] Other papers have been published showing similar findings. [9]

Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. The IUPAC name for an epoxide group is an oxirane.

In organic chemistry, an epoxide is a cyclic ether, where the ether forms a three-atom ring: two atoms of carbon and one atom of oxygen. This triangular structure has substantial ring strain, making epoxides highly reactive, more so than other ethers. They are produced on a large scale for many applications. In general, low molecular weight epoxides are colourless and nonpolar, and often volatile.
