The novel compound (3-nitro-4-methyl)-phenyl chloroformate is prepared by reacting (4-methyl)-phenyl chloroformate with nitric acid in the presence of sulfuric acid. The novel compound (3-nitro-4-methyl)-phenyl chloroformate is a valuable starting material for the preparation of dyes and crop protection agents and in particular is an intermediate for the preparation of 3-nitro-4-methylphenol, which is reduced to 3-amino-4-methylphenol.
这种新型化合物(3-硝基-4-甲基)-苯基氯甲酸酯是通过在硫酸存在下将(4-甲基)-苯基氯甲酸酯与硝酸反应制备的。这种新型化合物(3-硝基-4-甲基)-苯基氯甲酸酯是制备染料和农药的有价值的起始物质,特别是用于制备3-硝基-4-甲基酚的中间体,后者被还原为3-氨基-4-甲基酚。
