摘要 利用紫外光谱测定了云杉硫酸盐4-脱氧-4-己烯糖醛酸在甲酸钠中水解动力学。结果表明该水解反应为一反应速度较快的拟一级反应。此外,该水解反应的选择性较高,可望应用在无元素氯(ECF)和全无氯(TCF)漂白技术中。 The hydrolysis kinetics of 4-deoxy-4-hexenuronic acid(HexA) of Spruce Kraft pulp in formate solution was determined by UV Spectroscopy. The results indicate that the hydrolysis is a pseudo-first order reaction with faster rate,good selectivity in removing HexA and could be used for ECF and TCF bleaching sequences.
