  2. Acetanilide - Wikipedia

    en.wikipedia.org/wiki/Acetanilide

    Acetanilide can be produced by reacting acetic anhydride with aniline: [7]. C 6 H 5 NH 2 + (CH 3 CO) 2 O → C 6 H 5 NHCOCH 3 + CH 3 COOH. The preparation used to be a traditional experiment in introductory organic chemistry lab classes, [8] but it has now been widely replaced by the preparation of either paracetamol or aspirin, both of which teach the same practical techniques (especially ...

  5. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  6. Benzylideneacetone - Wikipedia

    en.wikipedia.org/wiki/Benzylideneacetone

    Benzylideneacetone is the organic compound described by the formula C 6 H 5 CH=CHC(O)CH 3. Although both cis- and trans-isomers are possible for the α,β-unsaturated ketone, only the trans isomer is observed. Its original preparation demonstrated the scope of condensation reactions to construct new, complex organic compounds. [1]

  7. 4-Aminoacetanilide - Wikipedia

    en.wikipedia.org/wiki/4-aminoacetanilide

    4-Aminoacetanilide or paracetamin is a chemical compound which is a amino derivative of acetanilide and para-isomer of aminoacetanilide. There are two other isomers of aminoacetanilide, 2-aminoacetanilide and 3-aminoacetanilide. Aminoacetanilide derivatives are important synthetic intermediates in heterocyclic and aromatic synthesis. These ...

    en.wikipedia.org/wiki/Divinylbenzene

    Divinylbenzene (DVB) is an organic compound with the chemical formula C 6 H 4 (CH=CH 2) 2 and structure H 2 C=CH−C 6 H 4 −HC=CH 2 (a benzene ring with two vinyl groups as substituents).It is related to styrene (vinylbenzene, C 6 H 5 −CH=CH 2) by the addition of a second vinyl group. [2]

  9. 2,4,6-Tribromoaniline - Wikipedia

    en.wikipedia.org/wiki/2,4,6-tribromoaniline

    2,4,6-Tribromoaniline can be prepared by treating bromine water with aniline in a solution of acetic acid or dilute hydrochloric acid: [1] By reacting bromine with aniline in water, a white precipitate immediately forms and that is 2,4,6-tribromoaniline
