Latest Patents

One of Upare's latest patents is titled "Method for producing lactide directly from lactic acid and a catalyst used therein." This invention provides a method for directly producing lactide by subjecting lactic acid to a dehydration reaction in the presence of a catalyst comprising a tin compound, preferably a tin (IV) compound. The method allows for the direct production of lactide from lactic acid without the need to produce or separate lactic acid oligomers. This innovative approach has several advantages, including no loss of lactic acid, a high conversion ratio to lactic acid, and a high selectivity for optically pure lactide. Additionally, the method maintains a long lifetime for the catalyst and minimizes the generation of lactic acid oligomers, thereby reducing purification costs.
