【Abstract】 Bi-phenolic methane is synthesized by the reactio n of phenol and formaldehyde solution in the presence of acid catalyst. Through orthogonal design experiments, the effective regularities of synthetic condition s on the yield rate and bi-nucleus ratio of bi-phenolic methane are discussed . The properties of bi-phenolic methane, such as molecular weight, melting poin t and bi-nucleus ratio are analyzed and their characteristics expounded.更多还原
