Abstract: The invention is a process for drying and purifying wet crude chloral which process comprises contacting the wet crude chloral with sulfuric acid solution in such manner that the solution in contact with the chloral has a concentration of about 50 percent or below, recovering the chloral, contacting the recovered chloral with concentrated sulfuric acid and utilizing the effluent acid recovered from the second contacting operation in first contacting of a subsequent process operation. Multistage, countercurrent flow arrangements are described. Hydrogen chloride and other acidic impurities are also substantially removed.
