2-Methylbenzophenone ine CAS 131-58-8
2-Methylbenzophenone imusanganiswa webenzophenone, inova kemikari yakanaka kwazvo. Panguva imwe chete, maketone ndiwo zvakare maumbirwo makuru emamorekuru akawanda eorganic, akadai sezvinhu zvinoshanda, zvinonhuwira uye mamorekuru emishonga. Maketone anonhuhwirira ndiwo maburiro akakosha ekugadzira mukugadzirwa kweorganic, ayo aripo zvakanyanya muzvikamu zvepakati zvezvigadzirwa zvechisikigo uye anoshandiswa zvakanyanya mumakemikari anoshanda muhupenyu.
| Chinhu | Zvakajairika |
| Chitarisiko | Mvura isina ruvara rweyero yakapfava |
| Kuyedza | ≥99.0% |
| Mvura | ≤0.20% |
Pasi pekuchengetedzwa kwegasi risina simba, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol %) uye biquinoline (bq, 3 mol %) zvakaparadzirwa mu organic solvent (2 mL) ), ipapo H2O (2 mmol) yakawedzerwa, uye tembiricha yakakwidzwa kusvika 80°C kwemaawa matanhatu. Zvadaro reaction solution yakabviswa katatu neEt2O (5 mL), organic phases dzakasanganiswa, uye solvent yakasvinudzwa nekumanikidzwa kwakaderera. Chigadzirwa chisina kuchena chakawanikwa chakaiswa column chromatography pa column ye silica gel (300-400 mesh), uye eluents dzaive petroleum ether , kuti chigadzirwa chainangwa chiwane 2-methylbenzophenone. Hunhu hwemakemikari: Mvura isina ruvara kana yero yakajeka. Nzvimbo yekunyunguduka inenge 134°C. Shandisa semushonga wemishonga.
