Abstract
There is provided a one-step process for the production of diols. There is provided a process for the conversion of diols in a one-step reaction to polyesters and to lactones, wherein the diols are reacted in the presence of a Group VIII (of the Periodic Table) catalyst with an oxidizing agent, i.e. an agent adapted to remove hydrogen from the reactants, the process being carried out at elevated temperatures. According to a specific embodiment diols having a certain number of carbons are directly converted to lactones, while another embodiment provides for the conversion of but-2-yne-1, 4-diol to butyrolactone.
