  2. Walter Reppe - Wikipedia

    en.wikipedia.org/wiki/Walter_Reppe

    In 1921, Reppe worked for BASF's main laboratory. From 1923, he worked on the catalytic dehydration of formamide to prussic acid in the indigo laboratory, developing this procedure for industrial use. In 1924, he left research for 10 years, only resuming it in 1934.

  3. Linear alkylbenzene - Wikipedia

    en.wikipedia.org/wiki/Linear_alkylbenzene

    Linear alkylbenzenes (sometimes also known as LABs) are a family of organic compounds with the formula C 6 H 5 C n H 2n+1. Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12 -C 15 , C 12 -C 13 and C 10 -C 13 , for detergent use. [ 1 ]

  5. Friedel–Crafts reaction - Wikipedia

    en.wikipedia.org/wiki/Friedel–Crafts_reaction

    In commercial applications, the alkylating agents are generally alkenes, some of the largest scale reactions practiced in industry.Such alkylations are of major industrial importance, e.g. for the production of ethylbenzene, the precursor to polystyrene, from benzene and ethylene and for the production of cumene from benzene and propene in cumene process:

  6. Raschig–Hooker process - Wikipedia

    en.wikipedia.org/wiki/Raschig–Hooker_process

    The Raschig–Hooker process's ability to make phenol makes it comparable to other methods, such as the Dow and Bayer process, which also converts benzene into phenol. In fact, the ability to recycle the hydrogen chloride made the Raschig–Hooker process preferable to the Dow and Bayer process, which requires its sodium chloride product to be ...

  7. August Wilhelm von Hofmann - Wikipedia

    en.wikipedia.org/wiki/August_Wilhelm_von_Hofmann

    August Wilhelm von Hofmann (8 April 1818 – 5 May 1892 [2]) was a German chemist who made considerable contributions to organic chemistry. His research on aniline helped lay the basis of the aniline-dye industry, and his research on coal tar laid the groundwork for his student Charles Mansfield's practical methods for extracting benzene and toluene and converting them into nitro compounds and ...

  8. Sandmeyer reaction - Wikipedia

    en.wikipedia.org/wiki/Sandmeyer_reaction

    The Sandmeyer reaction provides a method through which one can perform unique transformations on benzene, such as halogenation, cyanation, trifluoromethylation, and hydroxylation. The reaction was discovered in 1884 by Swiss chemist Traugott Sandmeyer , when he attempted to synthesize phenylacetylene from benzenediazonium chloride and copper(I ...

  9. Pentachloronitrobenzene - Wikipedia

    en.wikipedia.org/wiki/Pentachloronitrobenzene

    PCNB was originally synthesized in the laboratory in 1868. It was introduced to the agricultural world in the 1930s in Germany by Bayer AG as a substitute to mercurial pesticides. PCNB is prepared by chlorination of nitrobenzene at 60–70 °C in chlorosulfuric acid, with iodine as a catalyst. It can also be produced by the nitration of ...
