Effect of Cosolvent and Nonionic Surfactant on Partition Coefficient of Azadirachta Indica A. Juss. (Neem) Seed Oil in Water−Hexane at (298.15, 303.15, 308.15, and 313.15) K

The partition coefficient of Azadirachta Indica A. Juss. (neem) seed oil (NSO) in water + hexane was calculated by measuring the amount of NSO concentration in hexane by a UV spectrophotometric method at (298.15, 303.15, 308.15, and 313.15) K. The partition coefficients of NSO increased with an incr...

Beschreibung
Zusammenfassung:	The partition coefficient of Azadirachta Indica A. Juss. (neem) seed oil (NSO) in water + hexane was calculated by measuring the amount of NSO concentration in hexane by a UV spectrophotometric method at (298.15, 303.15, 308.15, and 313.15) K. The partition coefficients of NSO increased with an increasing amount of NSO, which indicates a hydrophobic interaction of NSO in the organic phase. Addition of cosolvent (methanol) or nonionic surfactant (polysorbate-80) to the water + hexane mixture decreased the partition coefficient of NSO in the temperature interval studied.
