摘要
文章汇总了萘与硫酸二磺化反应的副产2,6-萘二磺酸的综合利用方向,包括用其制备萘系高效减水剂、薛佛氏盐(2-羟基-6-萘磺酸盐)以及2,6-二羟基萘等三种化工产品。通过对该三种产品现状的叙述,表明2,6-萘二磺酸的综合利用尚需更为深入的研究才能真正实现变废为宝的这一绿色化学目标。
The schemes of the comprehensive utilization of naphthalene-2,6-disulfonic acid, which is the main byproduct in the snl- fonation of naphthalene with the sulfuric acid, were summarized, including the preparation of the naphthalene-based superplasticizer, the Schaeffer＇s salt and 2,6-dihydroxy naphthalene. According to the current research situations of the three products, it showed obvi- ously that the green chemistry of turning waste into wealth wouldn＇t be achieved until further research on the comprehensive utilization was done.
