二酚基甲烷的合成与表征

The Synthesis and Characterization of Bi-phenolic Methan e

利用正交实验,研究了苯酚和甲醛在酸性催化剂的作用下合成二酚基甲烷的反应。探讨了合成各条件对产物的收率、双核比例的影响,并对产物的分子量、熔点、双核含量进行了分析表征。

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.
