3-甲基-2-苯并噻唑啉酮腙鹽酸鹽性質(zhì)、用途與生產(chǎn)工藝
化學(xué)性質(zhì)
白色粉末。熔點(diǎn)為276-278℃（分解）。溶于水，微溶于無(wú)水醇。
用途
3-甲基-2-苯并噻唑酮腙可作染料的中間體。其鹽酸鹽MBTH是比色測(cè)定脂肪族醛和芒香族胺類(lèi)的試劑。
生產(chǎn)方法
由2-氨基苯并噻唑用硫酸二甲酯甲基化后再與水合肼縮合，得到3-甲基-2-苯并噻唑酮腙[1128-67-2]，最后用鹽酸成鹽即得成該品。在搪玻璃反應(yīng)鍋中加入無(wú)水氯仿和2-氨基苯并噻唑，加熱到60-61℃，攪拌15min，使2-氨基苯并噻唑溶解形成透明的溶液。冷卻到40℃，加入硫酸二甲酯，加熱回收氯仿60-61℃，攪拌反應(yīng)1h。加水，加熱回收氯仿至98℃。氯仿回收結(jié)束后，加水合肼，升溫至85-87℃，然后溫度自行上升至99℃，于98-99℃保持反應(yīng)6h，反應(yīng)過(guò)程中自始至終保持亮黃試紙顯紅?？s合反應(yīng)完畢，加水，冷卻至30℃，過(guò)濾，濾餅用水洗至對(duì)亮黃試紙不顯色，得3-甲基-2-苯并噻唑酮腙。收率約60%。用鹽酸成鹽即得MBTH。
