  2. Diethylbenzenes - Wikipedia

    en.wikipedia.org/wiki/Diethylbenzenes

    C 6 H 6 + C 2 H 4 → C 6 H 5 C 2 H 5. The diethylbenzene is an inadvertent side product. C 6 H 5 C 2 H 5 + C 2 H 4 → C 6 H 4 (C 2 H 5) 2. Using shape-selective zeolite catalysts, the para isomer can be produced in high selectivity. Much diethylbenzene is recycled by transalkylation to give ethylbenzene: [1] C 6 H 4 (C 2 H 5) 2 + C 6 H 6 → ...

  4. C4-Benzenes - Wikipedia

    en.wikipedia.org/wiki/C4-Benzenes

    The C 4-benzenes are a class of organic aromatic compounds which contain a benzene ring and four other carbon atoms. There are three tetramethylbenzenes , six dimethylethylbenzenes, three diethylbenzenes , three isopropylmethylbenzenes , three n -propylmethylbenzenes and four butylbenzenes .

  5. p-Xylene - Wikipedia

    en.wikipedia.org/wiki/P-Xylene

    The p-stands for para-, indicating that the two methyl groups in p-xylene occupy the diametrically opposite substituent positions 1 and 4. It is in the positions of the two methyl groups, their arene substitution pattern, that it differs from the other isomers, o-xylene and m-xylene. All have the same chemical formula C 6 H 4 (CH 3) 2. All ...

    For example, Paraffin has very large molecules and thus a high heat capacity per mole, but as a substance it does not have remarkable heat capacity in terms of volume, mass, or atom-mol (which is just 1.41 R per mole of atoms, or less than half of most solids, in terms of heat capacity per atom).

  9. Divinylbenzene - Wikipedia

    en.wikipedia.org/wiki/Divinylbenzene

    It is produced by dehydrogenation of diethylbenzene: C 6 H 4 (C 2 H 5) 2 → C 6 H 4 (C 2 H 3) 2 + 2 H 2. Divinylbenzene is usually encountered as a 2:1 mixture of m- and p-divinylbenzene, containing also the corresponding isomers of ethylvinylbenzene. Styrene and divinylbenzene react to form the copolymer styrene-divinylbenzene, S-DVB or Sty-DVB.
