Abstract

Colloidal particles of iron hydroxide produced by the hydrolysis of an iron(III) chloride solution in hot water catalyze the consumption of hydrogen peroxide and initiate the oxidative decomposition of impurities present in technical cellulose. This causes the bleaching of cellulose, and its degree depends on the concentrations of reagents and conditions of the process. The main products of the parallel oxidative destruction of cellulose itself are formic and other carboxylic acids. The regularities and features of the processes are analyzed; the kinetic parameters of the peroxide decomposition and acid formation are determined.

纤维素负载的氢氧化铁催化过氧化氢分解

摘要

由氯化铁（III）在热水中水解产生的氢氧化铁胶体颗粒催化过氧化氢的消耗，并引发工业纤维素中杂质的氧化分解。这引起纤维素的漂白，其程度取决于试剂的浓度和工艺条件。纤维素本身平行氧化破坏的主要产物是甲酸和其他羧酸。分析过程的规律性和特征；确定了过氧化物分解和酸形成的动力学参数。
