<p>This invention pertains firstly to the use of mixtures of hydriodic acid and organic solvent soluble iodide salts as catalysts for the hydration of gamma, delta-epoxyalkenes to form a mixture of the corresponding 2-alkene-1,4-diol and 3-alkene-1,2-diol isomers. Secondly, this invention describes the use of pH to control the 2-alkene-1,4-diol/3-alkene-1,2-diol product ratio, and achieves improved 2-alkene-1,4-diol selectivities by controlling the pH to near neutral values.</p> |
