Interpretation Introduction

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 40 °C . In other words, this procedure is applied for removal of nonvolatile impurities from volatile solvents. If one of the compounds in organic mixture is volatile, its vapors will form first and are converted into liquid with help of condenser. This way all of volatile compound gets converted into liquid and therefore it is separated from nonvolatile component.

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.
