Latest Patents

Lui Shuanghui holds a patent for a process titled "Recovery and purification of hydroxy fatty acids from source oils." This process involves several key steps: first, methylating the source oil to create hydroxy fatty acid methyl esters and non-hydroxy fatty acid methyl esters. Next, he separates the hydroxy fatty acid methyl esters from the non-hydroxy fatty acid methyl esters using an organic solvent mixture that includes pentane/hexane and a short-chain alcohol. Finally, he recovers both types of methyl esters from the organic solvent mixture. The hydroxy fatty acids that can be recovered through this process include ricinoleic acid, densipolic acid, lesquerolic acid, and auricolic acid. Additionally, the non-hydroxy fatty acid methyl esters can be further processed into biodiesel fuels and lubricants.
