Xylene Impurity analysis
Aromatic compounds such as ortho-Xylene, para-Xylene and meta-Xylene are aromatic isomers; these hydrocarbons are found in the chemical streams of crude oil. It is usually found in a mixture called BTX with Benzene and toluene and BTEX 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.
