"o"-xylene
"m"-xylene"p"-Xylene is an
aromatic hydrocarbon , based onbenzene with twomethyl substituent s. The “p” stands for "para", identifying the location of the methyl groups as across from one another.It is an isomer of
xylene . Other isomers include "o"-xylene and "m"-xylene."p"-Xylene is used on a large scale for the manufacture ofterephthalic acid forpolyester . Itspolymer is known asparylene .References
