Benzene Impurity Analysis
Aromatic compounds such as benzene hydrocarbons are found in the chemical streams of petroleum and crude oils. It is usually found in the mixture called BTX composed of benzene, xylene isomers and toluene as a mixture. BTEX can be made upon addition of ethylbenzene in BTX. This process requires good quality reagents therefore impurity analysis of the reagents is essential. High quality analyzers are required to determine the degree of purity.
