Mass Transfer Steam distillation is not recommended to be used, if the Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Azeotropic mixture is to be separated and the final product is miscible with water Liquids decompose, if distilled directly at atmospheric pressure Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Azeotropic mixture is to be separated and the final product is miscible with water Liquids decompose, if distilled directly at atmospheric pressure ANSWER DOWNLOAD EXAMIANS APP
