  2. Biphenyl - Wikipedia

    en.wikipedia.org/wiki/Biphenyl

    Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene [4] or BP) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl .

  3. Bisphenol - Wikipedia

    en.wikipedia.org/wiki/Bisphenol

    The bisphenols (/ ˈ b ɪ s f ɪ n ɒ l /) are a group of industrial chemical compounds related to diphenylmethane; commonly used in the creation of plastics and epoxy resins. [1] [2] [3] Most are based on two hydroxyphenyl functional groups linked by a methylene bridge.

  4. Bisphenol A - Wikipedia

    en.wikipedia.org/wiki/Bisphenol_A

    The synthesis of BPA still follows Dianin's general method, with the fundamentals changing little in 130 years. The condensation of acetone (hence the suffix 'A' in the name) [ 33 ] with two equivalents of phenol is catalyzed by a strong acid, such as concentrated hydrochloric acid , sulfuric acid , or a solid acid resin such as the sulfonic ...

  5. Phenyl group - Wikipedia

    en.wikipedia.org/wiki/Phenyl_group

    In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...

  6. Biphenyl synthase - Wikipedia

    en.wikipedia.org/wiki/Biphenyl_synthase

    In enzymology, a biphenyl synthase (EC 2.3.1.177) is an enzyme that catalyzes the chemical reaction: . 3 malonyl-CoA + benzoyl-CoA 4 CoA + 3,5-dihydroxybiphenyl + 4 CO 2. Thus, the two substrates of this enzyme are malonyl-CoA and benzoyl-CoA, whereas its three products are CoA, 3,5-dihydroxybiphenyl, and CO 2.

  7. Dihydroxybiphenyl - Wikipedia

    en.wikipedia.org/wiki/Dihydroxybiphenyl

    Dihydroxybiphenyl (as known as biphenol) refers to a class of organic compounds consisting of a biphenyl structure with two hydroxyl groups attached. The most common isomers are 2,2'-dihydroxybiphenyl and 4,4'-dihydroxybiphenyl.

  8. Bisphenol S - Wikipedia

    en.wikipedia.org/wiki/Bisphenol_S

    Bisphenol S (BPS, dioxydiphenylsulfone) is an organic compound with the formula (HOC 6 H 4) 2 SO 2.It has two phenol functional groups on either side of a sulfonyl group. It is commonly used in curing fast-drying epoxy resin adhesives.

  9. Biosynthesis - Wikipedia
