Origin: Formed within English, by compounding. Etymons: bis- comb. form¹, phenol n.

Etymology: < bis- comb. form¹ + phenol n.

Chemistry.

Any of a class of compounds containing two identically substituted phenol groups joined by a linking group; spec. bisphenol A.In quot. 1923 as part of the systematic name of such a compound.

ΚΠ

1923 Jrnl. Amer. Chem. Soc. 45 1063 The tetrabromo derivative of 4,4'-(2,4-dinitro-phenylmethylene)-bisphenol.

1949 Poultry Sci. 28 802 Among the chemical agents tested in this laboratory to determine their anti-coccidial activity several bisphenols and diphenols were found to be effective.

1997 Encycl. Brit. (Electronic ed.) Bisphenols such as hexyl resorcinol and hexachlorophene are widely used as antiseptic agents in soaps.

2005 Men's Health (U.K. ed.) June 23/3 University of Cincinnati scientists exposed disease samples to bisphenol, used in plastics, and found an increase in cancer-making cells.

Compounds

C1. attributive. With following letter or letters, denoting a particular bisphenol.The main variation between bisphenols is in the structure of the linking group. This forms the basis of a naming convention in which one or more letters are used, as bisphenol A, bisphenol F, bisphenol S, etc. The letter represents the first letter (or a significant letter) in the name of the reactant used to form the bisphenol from the base compound (typically phenol). So bisphenol B is formed from the reaction of phenol with butanone.Earliest in bisphenol A n. at Compounds 2.

ΚΠ

1938 Chem. Industries Aug. 130 (advt.) Bis Phenol-A (p, p'-Isopropylidene Bisphenol).

1947 Chem. Industries 61 432/2 Butylidenediphenol (Bisphenol B).

1971 M. W. Ranney Fluorocarbon Resins 86 This example illustrates the curing of a copolymer of VF₂..with either the dipotassium salt of bisphenol AF or a mixture of the dipotassium salt with bisphenol AF.

1998 New Scientist 14 Mar. 22/1 They dissolved Bakelite, or bisphenol-F, in ethanol.

C2.

bisphenol A n. a solid bisphenol used in the manufacture of plastics, esp. epoxy resins and polycarbonates; abbreviated BPA.Bisphenol A is formed by the reaction of phenol with acetone. Formula: HOC₆H₄C(CH₃)₂C₆H₄OH. It is a xenoestrogen and there are concerns about its health effects and persistence in the environment.

ΚΠ

1938 Chem. Industries Aug. 130 (advt.) Bis Phenol-A (p, p'-Isopropylidene Bisphenol).

1957 H. Lee & K. Neville Epoxy Resins i. 8 Bisphenol A or bis (4-hydroxyphenyl) dimethylmethane..requires two basic intermediates for synthesis, acetone and phenol.

2012 Daily Tel. 19 Oct. 32/3 In 2010, the EU banned the use of Bisphenol A in making babies' bottles.
