对传统硫酸盐蒸煮(CK)浆和延伸改良连续蒸煮(EMCC)浆进行了研究.结果表明,EMCC和CK 浆残余木素中游离酚羟基的含量没有明显的区别,EMCC的含量反而比CK的稍低一些.这说明EMCC纸浆的较高漂白性能与残余木素中的游离酚羟基的含量没有直接的关系.

The residual lignin of eucalyptus Conventional Kraft (CK) pulps and Extended Modified Continuous Cooking (EMCC) pulps were studied in this paper. There was no significant different content of free phenolic hydroxyl groups between CK and EMCC pulps, which suggested that higher bleachability of EMCC pulp was not simply related to the content of free phenolic hydroxyl groups, though free phenolic hydroxyl groups were believed to be the main and preferential site of attack by chlorine dioxide.
