Fine chemicals are chemical substances prepared to a very high degree of purity. They can be used in research and industry. The extraction of raw materials from plants is done in numerous steps. Firstly the plant is crushed in order to break open the plant material. It is then boiled and dissolved in a suitable solvent. Finally, chromatography takes place in order to separate the different chemicals in the plant. Aside from plant extraction, fine chemicals can also be extracted synthetically.http://www.tnnchemical.com/fine-chemicals/
