ABSTRACT OF THE DISCLOSURE Two novel compounds, trichlorophloroglucinol tripropyl- ether and trichlorophloroglucinol triisopropylether are disclosed, as well as the process for their preparation and for their hydro- lysis to form trichlorophloroglucinol. A process for their preparation comprises reacting hexachlorobenzene with sodium propylate or sodium isopropylate, in a molar ratio of about 1:3 to about 1:20, respectively, in an aprotic solvent, at a temperature from about 50 to about 250°C. The process for the preparation of the trichlorophloroglucinol comprises hydrolizing trichlorophloro- glucinol tripropylether or trichlorophloroglucinol triisopropyl- ether to form trichlorophloroglucinol.
