style="text-indent:25px">8-羥基喹啉，用作醫(yī)yao中間體，是合成克瀉痢寧、氯碘喹啉、撲喘息敏的原料，也是染料、農(nóng)yao中間體。用作沉淀和分離金屬離子的絡(luò)合劑和萃取劑，加入環(huán)氧樹脂膠黏劑中可提高對金屬(尤其是不銹鋼)的粘接強度和耐熱老化性，8-羥基喹啉是獸yao哈喹諾、電致發(fā)光材料8-羥基喹啉鋰的上游原料。8-羥基喹啉生產(chǎn)的傳統(tǒng)工藝:將甘油加入耐酸反應(yīng)鍋內(nèi)，在攪拌下加入鄰硝基苯酚，鄰氨苯酚，加熱滴加硫酸，生成8-羥基喹啉。經(jīng)過中和分油，油品經(jīng)過精餾分離，甲醇溶解再結(jié)晶、干燥得到粉狀結(jié)晶產(chǎn)品。新工藝特點:優(yōu)化反應(yīng)操作，提高反應(yīng)轉(zhuǎn)化率，回收母液中原料和產(chǎn)物，減少排放污染。8-羥基喹啉的化學反應(yīng)也是有明顯的差異的，一般的情況下8-羥基喹啉的用法用量為5%左右既能夠達到想要結(jié)果。南京8-羥基喹啉大概多少錢</p><p
