碘甲磺酸鈉是一种排洩性X光造影剂,其最大优点为制造簡便,成本低廉,几乎沒有什么付作用。特別是它的合成,对我国目前来說無論在原料、設备及技术上都沒有什么困难。碘甲磺酸鈉的合成方法很多,大致有: 1.二碘甲烷与亞硫酸鹽共热,其反应如下。 CH_2I_2+Na_2SO_3→ICH_2SO_2ONa+NaI Sodium iodo methanesulfonate is an excretion of X-ray contrast agent, its greatest advantage for the manufacture of simple, low cost, almost no pay role. In particular, its synthesis, for our country now no matter in raw materials, equipment and technology are no difficulties. Synthesis of iodine mesylate many ways, roughly: 1. Diiodomethane and sulfite co-heat, the reaction is as follows. CH_2I_2 + Na_2SO_3 → ICH_2SO_2ONa + NaI
