苯并氧杂蒽-3,4-二酸酐型染料的合成研究

A study on synthesis of benzoxanthene-3, 4-dicarboxylic anhydride derivatives

摘要: 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。

Abstract: Benzoxanthene-3, 4-dicarboxylic anhydride and its eight derivatives were synthesizedthrough chlorination, condensation, reduction, cyclization and imidation with 1, 8-naph-thalic anhydride as raw material, and the tendency of variation of their shade caused byintroduction of various groups to the derivative molecules was indicated. Dyeing polye-ster fibers with these derivatives was studied.
