Separating the two layers and measuring the volume of the aqueous layer.

Reactive Extraction Process in Isolation of Eugenol of Clove

Visible optimum conditions were different in each study variable. Theoretically it was known that the higher the reaction temperature the greater the reaction speed, which means the formation of more and more products, but this condition was limited to the optimum condition is reached. Peningkatan kadar eugenol pada minyak atsiri cenngkeh dengan metode saponifikasi — distilasi vakum.
