补充资料：氧碱漂白

分子式：
CAS号：

性质：以分子氧在碱性条件下将纸浆漂白的过程。它具有无氯漂白和无污染漂白的特点，因此是目前漂白方法发展的一个方向。氧碱漂白主要是分子氧的两个未成对的电子对有机物(纸浆中木质素)有强烈的反应倾向，而发生游离基反应。木质素经分子氧氧化，其结构单元的苯环和侧链被氧化，使木质素结构形成氧五环结构或羧酸的衍生物，并进一步形成各种内脂或醌式结构，侧链则发生断裂或消除，这样纸浆中木质素分子量变小而溶出达到漂白或精制的目的。一般纸浆浓度为25％～35％，温度为90～120℃，氧压0.6～1.2MPa，漂白时间约1h。为避免浆中重金属离子(如Mn2+、Fe2+等)对碳水化合物的催化降解，一般在氧碱漂白前可先用硫酸在pH=2.5～3的情况下进行酸处理。保护剂多为碳酸镁或镁的络合物(用量为0.03％～0.05％Mg2+对浆)，以提高漂白后纸浆的黏度与强度。
