Abstract
Method for dehydrating diols into diolefins and/or olefin alcohols by contacting said diols under dehydration conditions with a catalyst prepared by forming an intimate mixture of finely divided solid particles of at least one pyrophosphate and at least one acid orthophosphate of at least one metal belonging to the group consisting of lithium, sodium, strontium, and barium into a formed mass which is thereafter calcined to transform the acid orthophosphate into pyrophosphate.
