Procedure

In a preferred embodiment of the invention, pentachlorobenzonitrile is interacted with a molar excess of sulfuric acid having at least 75% by weight H2SO4 at a temperature of between about 130° and 160° C. for about fifteen (15) to ninety (90) minutes. The reaction mixture is then cooled and diluted with water to form a solid pentachlorobenzamide precipitate. The resultant pentachlorobenzamide is recovered in yields on the average of above about 90%.
