3-Aminotoluene 108-44-1
Category : Dyestuffs and Pigments
CAS NO : 108-44-1 EC NO : 203-583-1 MF : C7H9N MW : 107.15 Specification : 99% min Packing : 25kg，50kg 200kg Product description : What is the chemical of 3-Aminotoluene ? Appearance: Colorless transparent oily liquid; Assay:99%min by GC； IR Identity: conform to standard； HNMR： conform to standard； carbon spectrum: conform to standard； Water by K. F.:0.5% max or as per the customer’s request； Loss on drying:0.5% max. or as per the customer’s request； ================================================================================ use: 3-Aminotoluene is mainly used as an organic synthesis intermediate, with specific applications including: serving as an intermediate for cationic dyes and reducing dyes; used in the production of color film developers; acting as a solvent for polyester resins, an additive for polyurethane foam plastics, and a metal corrosion inhibitor; functioning as an intermediate in the synthesis of pharmaceuticals and pesticides; and also used as an analytical reagent, etc. ============================================================================= Synthesis route: 3-methylaniline (m-toluidine), its main industrial synthesis route is the reduction reaction of m-nitrotoluene, and commonly used methods include iron powder/hydrochloric acid reduction or catalytic hydrogenation. Traditional reduction method: m-nitrotoluene is reduced by heating in iron powder and dilute hydrochloric acid (or water) to produce 3-methylaniline, with stable yield and low cost, but a large amount of iron containing sludge is generated. Catalytic hydrogenation method: m-nitrotoluene reacts with hydrogen gas (pressure 1-3 MPa, temperature 80-120 ° C) in methanol/ethanol solvent under the action of nickel (such as Raney Ni) or palladium/platinum catalysts, with high selectivity and low pollution, making it a modern mainstream green process. Other methods include sodium sulfide reduction, electrolytic reduction, etc., but their industrial applications are limited. Uses : 3-Aminotoluene is mainly used as an organic synthesis intermediate, with specific applications including: serving as an intermediate for cationic dyes and reducing dyes; used in the production of color film developers; acting as a solvent for polyester re Synonyms : 3-Aminotoluene;3-Methylaniline;3-Methylbenzenamine;3-Toluidine;m-Toluamine;m-Tolylamine;Meta Toluidine;3-methylanilinium chloride; Molecular Structure :
