The compound consists of methane wherein two hydrogen atoms are replaced by two phenyl groups. It is a white solid. Diphenylmethane is a common skeleton in organic chemistry. The diphenylmethyl group is also known as benzhydryl.
This group typically excludes compounds in which either benzene is fused to another ring (bicyclic, tricyclic, polycyclic) [1] or includes a heteroatom, or where the methane connects to three or four benzenes. Ball-and-stick model of the benzhydryl radical. The benzhydryl radical can be abbreviated Ph 2 CH• or Bzh. [2]
Benzene is an organic chemical compound with the molecular formula C 6 ... toluene undergoes dealkylation to benzene and methane: ... (diphenyl) at higher temperature ...
Methylene diphenyl diisocyanate (MDI) is an aromatic diisocyanate. Three isomers are common, varying by the positions of the isocyanate groups around the rings: 2,2′-MDI, 2,4′-MDI, and 4,4′-MDI. The 4,4′ isomer is most widely used, and is also known as 4,4′-diphenylmethane diisocyanate. [3] This isomer is also known as Pure MDI.
A disubstituted phenyl compound (trisubstituted benzene) may be, for example, 1,3,5-trisubstituted or 1,2,3-trisubstituted. Higher degrees of substitution, of which the pentafluorophenyl group is an example, exist and are named according to IUPAC nomenclature.

The new targets are also supposed to be for all greenhouse gases: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride.
Methane, ethane, propane and butanes obtained primarily from natural gas processing plants. Methanol and formaldehyde. In 2007, the amounts of ethylene and propylene produced in steam crackers were about 115 Mt (megatonnes) and 70 Mt, respectively. [5] The output ethylene capacity of large steam crackers ranged up to as much as 1.0 – 1.5 Mt ...
