what is the difference between distillation and fractional distillation in tabular form?and dont tell mw that go to this link . give me this answer by typing in tabular form.
Simple distillation is used when the boiling points of chemicals in a mixture having large differences (more than 25°C).
Fractional distillation is used when the boiling points of chemicals in a mixture are close to each-other, usually within 77°F (25°C).
No fractionating columns used as the difference in the boiling point of mixture is large
Fractionating columns used to separate the mixtures.
E.g. Process used in separating kerosene and petrol
E.g. Process used in the separation of Crude Oil into useful fractions
The main difference between fractional distillation and simple distillation is the application in which they are used. Fractional distillation separates component parts when they have a boiling point less than 25 degrees C of each other. Simple distillation works when the differences in boiling points between the compounds are greater than each other.Both start out with a heating device and astill pot. The liquid in the still pot is heated until the first component boils and starts to evaporate. In fractional distillation, the vapor moves up the fractionating column. Inside this column are several cooling trays. The vapor will condense as it reaches the trays, and only the vapor with the lowest boiling point will then move into the condenser where it is converted back to its liquid form.In a simple distillation, since the components have such varying boiling points there is no need for a fractionating column. The liquid is brought to a boil in the still. It then moves up the still head and into the condenser where it is cooled back to a liquid.
