It is although believed that crude forms of distillation‚ the main method that essential oils are now obtained‚ were practiced thousands of years ago in Persia‚ Egypt and India. Distillation was used mainly for the extraction of exotic flower waters. The medicinal use of plants and their extracts in India has been continuous from 5‚000 years ago to the present day

mentioned PTC is described in the text along with the mechanism for the addition of a dichlorocarbene. The percentage yield obtained was 38.80%. This is considerably low due to an unfortunate spillage of the product at the stage of semi- micro distillation. Introduction Phase transfer catalysts (PCT) are used to catalyze reactions involving chemical species which are present in different phases. These types of reactions are known as a homogeneous two phase reactions and are usually very

drinking‚ irrigation‚ or industrial uses. The principal methods used for desalination include distillation (or evaporation)‚ electrodialysis‚ freezing‚ ion exchange‚ and reverse osmosis. In distillation saltwater is heated in one container to make the water evaporate‚ leaving the salt behind. The desalinated vapor is then condensed to form water in a separate container. Although long known‚ distillation has found limited application in water supply because of the fuel costs involved in converting

drugs used in the world‚ and is manufactured in huge quantities. The starting material for the commercial manufacture of paracetamol is phenol‚ which is nitrated to give a mixture of the ortho and para-nitrotoluene. The o-isomer is removed by steam distillation‚ and the p-nitro group reduced to a p-amino group. This is then acetylated to give paracetamol. Method * Place 2g of the 4-aminophenol into a 50cm3 conical flask‚ add 15cm3 of water and stir the suspension vigorously (magnetic stirrer)

In effect‚ refineries use fluid catalytic cracking to correct the imbalance between the market demand for gasoline and the excess of heavy‚ high boiling range products resulting from the distillation of crude oil. As of 2006‚ FCC units were in operation at 400 petroleum refineries worldwide and about one-third of the crude oil refined in those refineries is processed in an FCC to produce high-octane gasoline and fuel [4][5] oils.
