Chemische Eigenschaften
Colorless to pale yellow low melting solid
Occurrence
Has apparently not been reported to occur in nature.
Verwenden
Diphenylmethane, is used as an adhesive chemical composition for making flexible laminates for use in food packaging.
synthetische
By interaction of benzyl chloride and benzene in the presence of an acid cata lyst.
Definition
ChEBI: A diarylmethane that is methane substituted by two phenyl groups.
Stoffwechsel
Diphenylmethane is hydroxylated in the rabbit and some 15% of the dose is excreted as 4-hydroxydiphenylmethane, which is largely (80-90%) in the free state. Neither the hydrocarbon nor its metabolite is oestrogenic. This reaction also occurs in the dog (Williams, 1959).
l?uterung methode
Sublime it under vacuum, or distil it at 72-75o/0.4mm. Recrystallise it from cold EtOH. It has also been purified by fractional crystallisation from the melt. [Armarego Aust J Chem 13 95 1960, Beilstein 5 II 498, 5 IV 1841.]
