Anisole yog tus qauv reagent ntawm ob qho tib si tswv yim thiab kev qhia txog tus nqi. Nws tuaj yeem npaj tau los ntawm Williamson ether synthesis; sodium phenoxide yog reacted nrog ib tug methyl halide los yield anisol.
Yuav ua li cas koj yuav npaj anisole los ntawm Williamson txoj kev?
Ua tiav cov kauj ruam los ntawm cov lus teb:
Anisole yog npaj los ntawm kev ua ntawm methyl iodide ntawm sodium phenoxide. Cov tshuaj tiv thaiv no hu ua Williamson's synthesis. Williamson's synthesis: Qhov no yog ib txoj hauv kev zoo tshaj plaws rau kev npaj ethers. Nws koom nrog kev kho mob ntawm alkyl halide nrog cov tshuaj sodium alkoxide uas tsim nyog.
Y Yuav siv cov anisole yog dab tsi?
Anisole yog cov khoom siv raw khoom pib los hloov tshuaj los ntawm Pharmaceuticals Industries (qib txuj ci). Nws cov tsos yog cov kua ntshiab. Anisole nthuav qhia ntau yam kev siv: solvent rau tshuaj lom neeg cov tshuaj tiv thaiv, synthesis intermediates thiab hnyav rau electronics.
Cov tshuaj tiv thaiv ntawm anisol yog dab tsi?
Cov phenol reacts nrog sodium hydroxide thiab muab phenoxide ion uas reacts nrog methyl muab anisol. Nov yog cov lus teb yog lawm.
Yuav ua li cas anisole npaj los ntawm Williamson txoj kev sib txuas muab qhov sib npaug?
Anisole lossis methoxy benzene yog cov organic compound nrog cov mis CH3OC6H5 .…
- Williamson's synthesis. C6H5−ONa+Br−CH3 →C6H5−OCH3+NaBr.
- 2. Los ntawm methylation ntawm sodium phenoxide nrog dimethylsulfate los yog methyl chloride. 2C6H5−ONa(CH3O)2SO2→−Na2SO42C6H5−OCH3.
- Siv diazomethane.
