The potential energy surfaces (PESs) of three nitrotoluene isomers, such as p -nitrotoluene, m -nitrotoluene, and o -nitrotoluene, have been theoretically built at the CCSD (T)/CBS level. The geometries of reactants, transition states (TSs) and products are optimized at the B3LYP/6-311++G (d,p) level. Results show that reactions of –NO 2

p-Nitrotoluene 99-99-0 >95 4. First-aid measures General Advice Show this safety data sheet to the doctor in attendance. Immediate medical attention is required. Eye Contact In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.
Hazardous Substances Data Bank (HSDB) In 14-day studies, o-nitrotoluene, m-nitrotoluene, or p-nitrotoluene was administered in the feed to male and female rats and mice at concentrations ranging from 388 to 20000 ppm (5 animals/chemical/species/sex/dose). It is well known that symmetric molecules have higher melting points than nonsymmetric ones, e.g. p-nitrotoluene is a solid, o-and m-nitrotoluenes are liquids. For chemical formulation of pharmaceuticals, symmetry can be obtained by preparing twin drugs (see Chapter 16 ). Answer. Friedel crafts alkylation of benzene with methyl chloride in presence of anhydrous aluminium chloride gives toluene. nitration of toluene with a mixture of dil nitric acid and dil sulphuric acid gives a mixture of ortho and para nitro toluene which are separated by fractional distillation.
