4－氨基－6－硝基间苯二酚盐酸盐及其制备和应用
摘要：
本发明涉及4－氨基－6－硝基间苯二酚盐酸盐和制备及其在制备聚对苯撑苯并二噁唑AB型新单体的前体：5－硝基－6－羟基－2－(对甲氧羰基苯基)苯并噁唑中的应用。4－氨基－6－硝基间苯二酚盐酸盐应用于制备聚对苯撑苯并二噁唑AB型新单体的前体：5－硝基－6－羟基－2－(对甲氧羰基苯基)苯并噁唑，具有稳定性好、制得PBO分子量更高、既可避免气体干扰又可提升新单体在PPA中的溶解度之特点；4－氨基－6－硝基间苯二酚的制备以4，6－二硝基间苯二酚为原料，无需任何昂贵的催化剂，并方便控制二个硝基的单个还原、避免了4，6－二氨基间苯二酚(DAR)副产物的生成，操作方便、应用有效，且回收的醇溶剂经精馏后可循环使用、实现了清洁化工业生产。
摘要（英）：

This invention involves 4-amino-6-nitryl resorcinol hydrochloride and its preparation. It also involves the applying of 5-nitro-6-hydroxyl-2 -(4-methoxycarbonylphenyl)benzoxazolyl, the precursor of AB-type new monomer of PBO preparation. Whether 4-amino-6-nitryl resorcinol hydrochloride applies in 5-nitro-6-hydroxyl-2-(4-methoxy carbonylphenyl)benzoxazolyl, the precursor of PBO preparation, it is stabilising and the molecular weight of POB is higher. Its raw material is 4,6-dinitryl resorcinol, needing no costly catalyst, and convenient to control singleness reversion of the two nitryl, avoid production of DAR outgrowth; it is easy to operate, use effectively, and the alcohol solvent can recycle after rectification.
