以1,8-萘酐为原料,经过氯化(重量产率82%)、缩合(71%)、还原(90%)、环构(98%)、亚酰胺化等反应步骤,合成了苯并氧杂蒽-3,4-二酸酐及其八种衍生物。提出了引入不同基团时,衍生物色光的变化趋势,并研究了其衍生物在聚酯纤维上的染色应用性能。结果表明:所得的染样具有强烈的绿色荧光,且色泽鲜艳,耐升华牢度一般为4—5级,耐晒牢度最好的可达5级。 Benzene was synthesized from 1, 8-naphthalene anhydride by the reaction steps of chlorination (82% by weight), condensation (71%), reduction (90%), cyclization (98% Xanthene-3,4-dianhydride and eight derivatives thereof. The tendency of the color change of the derivatives when different groups were introduced was proposed. The dyeing properties of the derivatives on the polyester fibers were also studied. The results showed that: the obtained dye sample has a strong green fluorescence, bright color, sublimation fastness is generally 4-5 level, the best light fastness up to 5 levels.
