2,4-Difluoroaniline

CAS367-25-9

Hunhu hwemakemikari: chinhu chine mafuta cheyero isina kujeka.

Mashandisirwo: 2,4-Difluoroaniline imhando yepakati mukugadzirwa kweorganic. Mumishonga, inoshandiswa mukugadzirwa kwe difluorophenylsalicylic acid ne polyfluorodiphenyl acid. Difluorophenylsalicylic acid imhando ye carboxylic acid nonsteroidal anti-inflammatory drug (NSAID), ine zita rekuti international nonproprietary name (INN) Diflunisal. Iyi mishonga mitsva inobva ku salicylic acid, kunyange isina acetyl group ye aspirin, ine difluorophenyl group, zvichikonzera kushomeka kwemigumisiro ye antiplatelet, kusagadzikana kwemudumbu, uye kushanda kwenguva yakareba kwemaawa 8-12. Ingave iri mushonga we salicylic acid unovimbisa zvikuru. Imhando yakakoshawo mukugadzirwa kwemishonga inouraya zvipembenene.

Nzira Yokugadzira 1. Nzira Yokuderedza 2,4-Difluorinitrobenzene: Upfu hwesimbi neammonium chloride mvura zvinowedzerwa kune reduction reactor, zvopiswa kuti zvisandurwe, uye 2,4-difluorinitrobenzene inowedzerwa nedonhwe. Mushure mekunge kuwedzera kwapera, dzokorora kwemaawa maviri. Mushure mekunge reaction yapera, chigadzirwa chinonyungudutswa nemhepo, choparadzaniswa neChemicalbook, uye choomeswa necalcium chloride kuti chiwane chigadzirwa chakakodzera chine goho re87%. 2. Chinowanikwa kubva ku1,2,4-trichlorobenzene kuburikidza ne nitration, fluorination, uye reductive dechlorination; kana kuti chinowanikwa kubva ku m-phenylenediamine kuburikidza ne diazotization, substitution, nitration, uye reduction.
