Abstract
This invention relates to an improved process for the production of hydroxyketones, especially dihydroxyacetone, by the condensation of one or more aldehydes in the presence of a catalyst and the use of specific process train. The product of this process is a relatively pure and any waste products from the reaction are environmentally friendly because none of the chemical components are discharged into the waste streams.
