実験手順

A mixture of 31.5 grams of 3-chloronitrobenzene, 450 milliliters of 5N-sodium sulphite solution and 500 milliliters of 2N sodium hydroxide solution was refluxed with stirring for 90 minutes, acidified with concentrated hydrochloric acid, and refluxed for 1 hour. On cooling and diluting with water a solid crystallised out which was filtered and washed with water to give 9.9 grams of 2-chlorosulphanilic acid.
