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。
This paper summarizes the comprehensive utilization of 2,6-naphthalenedisulfonic acid, a byproduct of the reaction between naphthalene and sulfuric acid, including its preparation of naphthalene superplasticizer, chevron salt (2-hydroxy-6-naphthalene sulfonate Acid salt) and 2,6-dihydroxy naphthalene three kinds of chemical products. Through the description of the status quo of the three products, it shows that the comprehensive utilization of 2,6-naphthalenedisulfonic acid needs to be studied in more depth so that the green chemical target of turning waste into wealth can be truly achieved.
