摘要: Hydroxy sulfonic acids in general and isethionic acid (2-hydroxy ethyl sulfonic acid) in particular can be prepared at 99+% purity and good yields by the selective oxidation of a precursor hydroxy mercaptan with hydrogen peroxide. The resulting product is pure enough to be used directly in the synthesis of sulfo-acrylic esters which are finding considerable use as stabilizers in producing vinylidene chloride copolymers used for FDA approved packaging films.
摘要翻译: 通常通过用过氧化氢选择性氧化前体羟基硫醇,通常可以制备羟基磺酸和羟乙磺酸(2-羟基乙基磺酸),其纯度为99 +%,产率高。 所得产物纯度足以直接用于磺基丙烯酸酯的合成中,其在制备用于FDA批准的包装膜的偏二氯乙烯共聚物中被认为可用作稳定剂。
