甲基橙制备

1.由对氨基苯磺酸经重氮化后与N，N-二甲基苯反应而得。将对氨基磺酸溶解于2.5%的碳酸钠溶液中，加入亚硝酸钠，待完全溶解后，加入碎冰和盐酸进行重氮化反应，析出重氮盐结晶。向重氮盐溶液中加入N，N-二甲基苯胺和冰醋酸的混合液，搅拌10min后慢慢加入10%氢氧化钠溶液至碱性。冷却结晶，过滤，用饱和盐水洗涤，干燥，用水重结晶，得甲基橙。

2.在盛有6L氢氧化钠（ 2mol/l）的搪瓷容器中，加入2kg对氨基苯磺酸，加热使之完全溶解（溶液对石蕊试纸呈碱性）。然后加800g亚硝酸钠，搅拌溶解，并用冰冷却至5℃。所得溶液在不断搅拌下缓慢加到5L2mol/L 盐酸和10kg碎冰的混合液中，冷却，静置15min。用淀粉碘化钾试纸确定重氮化反应终点（试纸变蓝）。上述过程反应式为：

制得的溶液在搅拌下加到事先制好的1200g二甲苯胺与10L1mol/L酸的冷溶液中，混合均匀后，静置10min，慢慢加入20%的氢氧化钠溶液至明显碱性，沉淀出黄色鳞片状的甲基橙结晶：

粗品加热至全部溶解后，加入2kg化学纯食盐并加热搅拌至溶解，用水冷却结晶，抽滤，然后再用少量热蒸馏水溶解（每20ml热水溶解1g结晶），趁热过滤，滤液冷却结晶，吸干，再依次用少量乙醇、乙醚洗涤，干燥即得成品。
