A new 1,3-bis(3-formyl-4-hydroxyphenyl)adamantane, which provides a material offering excellent properties such as heat resistance and mechanical strength for use as an intermediate material for adamantanebisphenol derivatives or use in photosensitive resist materials, epoxy resins and other synthetic resins, thermosensitive recording materials, and the like, can be obtained through an industrial process in an easy manner at a good yield and high purity by producing a Schiff base from a 1,3-bis(4-hydroxyphenyl)adamantane by causing it to react with a hexamethylenetetramine or other substance in the presence of an acid, and then hydrolyzing the obtained Schiff base using an acid. A new polynuclear polyphenol is also provided that may be derived from the same.
一种新的1,3-双(3-甲醛基-4-羟基苯基)金刚烷,可作为金刚烷双酚衍生物的中间体材料或用于光敏感抗蚀材料、环氧树脂和其他合成树脂、热敏感记录材料等,具有优异的性能,如耐热性和机械强度。可以通过一个工业过程轻松获得这种材料,产率高,纯度高,方法是通过将1,3-双(4-羟基苯基)金刚烷与六亚甲基四胺或其他物质在酸的存在下发生反应,然后用酸水解得到的席夫碱。同时还提供了一种可能源自相同材料的新的多核多酚。
