What is O nitrotoluene used for?

What is O nitrotoluene used for?

Typical use of nitrotoluene is in production of pigments, antioxidants, agricultural chemicals, and photographic chemicals. Ortho-mononitrotoluene and para-mononitrotoluene can be also used as detection taggants for explosive detection.

What is the major product of nitration of toluene?

The nitration of toluene results in ortho and para nitrotoluene isomers. When it is heated it results in dinitrotoluene and trinitrotoluene which is explosive.

1, 2-dimethylbenzene.

Why is sulfuric acid used in nitration?

Sulfuric acid is needed in order for a good electrophile to form. Sulfuric acid protonates nitric acid to form the nitronium ion (water molecule is lost). The nitronium ion is a very good electrophile and is open to attack by benzene. Without sulfuric acid the reaction would not occur.

What is the melting point of 1 methyl 2 nitrobenzene?

What are the symptoms of o-nitrotoluene toxicity?

O-NITROTOLUENE is toxic by inhalation, ingestion and skin aborption, targeting the blood, central nervous system, skin, and gastrointestinal tract. Symptoms include, anoxia, weakness or dizziness, nausea and vomiting. If it contacts the eye, the eye should be irrigated immediately. If it contacts the skin, the area should be washed with soap.

How are nitrotoluenes made commercially?

Nitrotoluenes are produced commercially, as a mixture, by nitration of toluene. Typical end-use markets for the Nitrotoluenes and their derivatives are main materials for the synthesis of imaging products like pigment, dyestuffs,and photographic chemicals.

What is the formula for ortho-nitrotoluene?

2-Nitrotoluene or ortho-nitrotoluene is an organic compound with the formula CH 3 C 6 H 4 NO 2. It is pale yellow liquid that crystallizes in two forms, called α (−9.27 °C) and β (−3.17 °C). It is mainly a precursor to o-toluidine, which is an intermediate in the production of various dyes. It is made by nitrating toluene at above -10 °C.

Is nitrotoluene toxic to humans?

P-nitrotoluene appears as a yellow liquid with a weak aromatic odor. Toxic. Insoluble in water. Combustible but may take some effort to ignite. Produces toxic oxides of nitrogen when burned. In a spill, immediate steps should be taken to limit its spread to the environment.
