Synthesis of Fatty Acid Derivatives of p-Hydroxyphenylurea

Abstract

1) Electrolytic reduction of nitrobenzene in 82% H₂SO₄ resulted in the formation of p-aminophenol sulfate in a pure state with fairly good yield.
2) p-Hydroxyphenylurea was obtained with a good yield by heating together p-aminophenol sulfate and 2mol. urea over a water bath with Sn as a catalyst.
3) Several kinds of new compounds were obtained by the acylation of the OH-radical in p-hydroxyphenylurea with higher fatty acid residues.
