Apr 20 2019 Fractional distillation It is employed for separating two or more volatile liquids having boiling points close to each other egAcetone bpt 60C and methanol bpt 65CThe vapours of the liquids pass through the fractionating column which provides greater space for their coolingThe vapours of high boiling fractions condense and fall back into distillation flask.

Oct 08 2019 Molecular distillation uses a very high vacuum system which effectively reduces the pressure in the system to zero and allows compounds to essentially vaporize instantaneously1 The distillate proceeds in a continuousfeed fashion and the rate of distillation depends on flow velocity and surface area of the heating and cooling blocks.
Oct 16 2019 Here are examples of organic chemistry at work Polymers consist of long chains and branches of moleculesCommon polymers you encounter every day are organic moleculesExamples include nylon acrylic PVC polycarbonate cellulose and polyethylenePetrochemicals are chemicals derived from crude oil or petroleum.
