摘要：

8-Hydroxyquinoline has been prepared by the sulfonation of quinoline followed by alkali fusion of the resulting quinoline-8-sulphonic acid. The optimum conditions for sulphonation are: temperature, 140 C; duration of reaction, 2 hr; and proportion of quinoline to oleum (40%), 1:4. In alkali fusion, maximum yield is obtained by carrying out the fusion with sodium hydroxide at 300 C for 15 min.
