Interpretation:Use of steam distillation than simple distillation for isolation of citral from lemon grass oil should be determined.
Concept introduction:Simple distillation is separation technique that is used to separate mixture of organic compounds with difference in their boiling points more than
Steam distillation is technique that is used to separate and purify volatile compounds either immiscible or almost immiscible in water. This method makes use of codistillation of mixture of water and other organic liquids. This can also be applied for separation and purification of some organic solids.
