2,4,6-Trimethylaniline

Chemical name: 2,4,6-trimethylaniline

CAS：88-05-1

Molecular formula: C9H13N

Properties: This product is a light yellow oily liquid, with a specific gravity of 0.9633 and a boiling point of 232.3 ℃. It is slightly soluble in water and is easily soluble in organic solvents such as acetone. It is easy to oxidize when exposed to light, and its color darkens.

Specification: content ≥ 99%

Uses: dye intermediates, pesticide intermediates

Trimethylaniline is a colorless rhombic crystal, melting point 155 ℃, soluble in alcohol, acetone, etc., and slightly soluble in water.

It can be used as an intermediate of fuel, pesticide, medicine and photoinitiator, and can synthesize trimethylamine and polymer photoinitiator.

Production method: mix sulfuric acid and nitric acid into mixed acid, nitration with mesitylene under 10 ℃ under atmospheric pressure for 4h, stand for layering, and discharge the waste acid. The obtained 2,4,6-trimethylnitrobenzene, iron powder, hydrochloric acid and water were proportioned at the ratio of 1:3.74:0.9:2.22 (mol) and reduced at 100-105 ℃ for 8h. Then crude trimethylaniline is distilled from the reducing substance, and then purified by distillation.
