  一锅法制备3,3’,4,4’-四烷基二苯甲酮的方法

  摘要：

  本发明公开了一种一锅法制备3,3’,4,4’-四烷基二苯甲酮的方法，属于化学合成领域。该方法以邻二烷基苯为原料，以路易斯酸和浓硫酸为催化剂，将所述的原料和催化剂混合后形成混合液，在所述的混合液中滴加四氯化碳，滴加完毕后，在温度为0～30℃的条件下保温0.5～5h。相对于现有技术，本发明技术方案将两步合成方法简化为一锅法，简化了工艺，操作更加简便，只需要一步后处理即可得到产品，提高了产能。且该合成方法对温度没有很高要求，全程不需要加热或冷却，对设备也没有特殊要求，操作安全简便。

  A polyimide polymer, polyimide film and polyimide laminate plate including the same are provided. The polyimide polymer includes Formula (I), Formula (II) and Formula (III). In Formula (I), Formula (II) and Formula (III), A is an aromatic group with fluorine, B, B′, and B″ are aromatic groups different from one another. B/(B+B′+B″), B′/(B+B′+B″), and B″/(B+B′+B″) are larger than 0. The polyimide film includes a film layer which includes the above polyimide polymer. The film layer optionally includes colorants or inorganic nanoparticles. Therefore, the thermal resistance and the transparency of the polyimide film are improved, and a polyimide film with high thermal resistance and different colors is available. The polyimide solution can also be applied on metal film to form polyimide laminate plate.
