디페닐메탄 C화학적 특성, 용도, 생산
화학적 성질
Colorless to pale yellow low melting solid출처
Has apparently not been reported to occur in nature.용도
Diphenylmethane, is used as an adhesive chemical composition for making flexible laminates for use in food packaging.제조 방법
By interaction of benzyl chloride and benzene in the presence of an acid cata lyst.정의
ChEBI: A diarylmethane that is methane substituted by two phenyl groups.신진 대사
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).Purification Methods
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.]디페닐메탄 준비 용품 및 원자재
