Versuchsvorschrift

3-Nitro-4-Chloro-benzene-sulfonic acid-phenylester was obtained by mixing 51 g of 3-nitro-4-chloro-benzene-sulfonic acid-chloride with 18.8 g of phenol in 120 ml of acetone, and by adding 28 ml of triethylamine dropwise, while cooling, at a temperature not exceeding 10° C. The mixture was continued to be stirred for several hours at room temperature, and then water was added, in which process an oil was separated which was extracted with ether. After recrystallization of the residue from methanol, 54 g of 3-nitro-4-chloro-benzene-sulfonic acid-phenylester were obtained, which had a melting point of 71° C.
