Recovery of Aleuritic Acid from Seedlac

• An improved process of recovery of aleuritic acid from seedlac by reducing the reaction time with improved yield and purity
• Reduces the environmental pollution meanwhile enhance the economics to the aleuritic acid manufacturers.

Aleuritic acid is a natural product obtained by the alkaline hydrolysis of seedlac and purification by various steps including recrystallization and charcoal treatment. The existing process for the recovery of aleuritic acid is very tedious and it needs 15-20 days per batch production. Also the recovery of aleuritic acid is 12-14% yield w.r.t. seedlac, results less profit for the manufacturers. Sometimes the quality of the product is not up to the standards of acceptable purity. Hence, better process of recovery of aleuritic acid are required to increase the yield and purity also to reduce the duration and cost of production process. The present technology addresses the recovery of aleuritic acid with improved yield and purity by reducing the time and also it is cost-effective process.

• Improved the yield of Aleuritic Acid to 18-22% (from 10-12%)
• process economy improves
• Reduced reaction time to 2-5 days (from 10-15 days)
• Reduced the number of steps in the process
• Achieved the required purity without recrystallization.
