3-甲基 - 6-胺基苯酚一般由 3-甲基 - 6-硝基苯酚还原制得。还原方法有 :1.锡 +浓盐酸 [1] ;2 .瑞尼镍氢化还原 [2 ] ,收率为 76% ;3.硫酸 -硫酸铜溶液中电解还原[3 ] ,收率为 46% ;4.保险粉 (连二亚硫酸钠 )在碳酸钠或氢氧化钠存在下还原[4,7] ,收率为 59.7%。我们认为用保险 3-Methyl-6-aminophenol is generally prepared by the reduction of 3-methyl-6-nitrophenol. The reduction method is as follows: 1. Tin + concentrated hydrochloric acid [1]; 2. Raney nickel hydrogenation reduction [2], the yield is 76%; 3. Electrolytic reduction in sulfuric acid-copper sulfate solution [3] %; 4. Insurance powder (sodium dithionite) in the presence of sodium carbonate or sodium hydroxide reduction [4,7], the yield was 59.7%. We think of insurance
