A liquid with high boiling point decomposes on simple distillation but it can be steam distilled for its purification .Explain how is it possible? |
|
Answer» In steam, distillation boiling occurs when the vapour pressure of organic compound & steam becomes equal to atmospheric pressure. As vapour pressure of water is higher than the organic liquid. Therefore, organic liquid vaporizes at a temperature below its boiling point in steam distillation without decomposing. |
