Local: Mesitylene is the common name of 1,3,5-Trimethylbenzene (triply methylated benzene) occurring in petroleum and coal tar or converted from acetone on distillation with sulphuric acid. It is used a solvent for resins, gums, and nitrocellulose. It is used in manufacturing lacquers, paints, and varnishes. It is used as an intermediate for the manufacturing other chemical compounds including antioxidants. There are three isomeric compounds of trimethyl benzene, which all have trivial names respectively. The 1,2,3- isomer is called Hemellitol (or Hemimellitene); 1,2,4- isomer is called Pseudocumene; 1,3,5- isomer is called Mesitylene (or Mesitelene).  They are prepared from petroleum and coal tar and used as solvents for resins, gums, and nitrocellulose. and used as intermediates for the manufacturing other chemical compounds.
