  2. Bisphenol - Wikipedia

    en.wikipedia.org/wiki/Bisphenol

    [1] [2] [3] Most are based on two hydroxyphenyl functional groups linked by a methylene bridge. Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name ; the letter following denotes the variant, which depends on the additional substituents.

  3. 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 .

  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 ...

  6. PCB congener list - Wikipedia

    en.wikipedia.org/wiki/PCB_congener_list

    The twelve congeners that display all four of the descriptors are referred to as being "dioxin-like", referring both to their toxicity and structural features which make them similar to 2,3,7,8-tetrachlorodibenzo-p-dioxin (2378-TCDD). [1] Individual congeners are identified by the number and position of the chlorine atoms around the biphenyl ...

  7. Biomimetic synthesis - Wikipedia

    en.wikipedia.org/wiki/Biomimetic_synthesis

    Biomimetic synthesis is an area of organic chemical synthesis that is specifically biologically inspired. The term encompasses both the testing of a "biogenetic hypothesis" (conjectured course of a biosynthesis in nature) through execution of a series of reactions designed to parallel the proposed biosynthesis, as well as programs of study where a synthetic reaction or reactions aimed at a ...

  8. Aperiodic crystal - Wikipedia

    en.wikipedia.org/wiki/Aperiodic_crystal

    The biphenyl molecule is a simple organic molecular compound consisting of two phenyl rings bonded by a central C-C single bond, which exhibits a modulated molecular crystal structure. Two competing factors are important for the molecule's conformation.

  9. 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.
