How is 1,1-Propanediol (CAS: 26264-14-2) typically synthesized?

1,1-Propanediol (CAS: 26264-14-2) can be synthesized through the hydration of propylene oxide, with a high selectivity of up to 99%. Alternatively, it can be produced from the biological fermentation of sugars, which provides a more sustainable route. The process often involves the use of catalysts like sulfuric acid or sodium hydroxide to enhance the reaction efficiency.
