2-(Trifluoromethoxy)benzoic acid (CAS# 1979-29-9) Nhanganyaya
TFMPA ikristaro isina ruvara, inonyungudika muorganic solvents senge benzene uye ethanol. Iine acidity yakasimba uye oxidation, uye inonzwa kumvura.
Shandisa:
TFMPA inoshandiswa zvakanyanya se acid catalyst, oxidant uye catalyst ye esterification mune organic synthesis. Inogona kukurudzira kufambira mberi kwemakemikari kuita uye kuvandudza kusarudza uye goho rekuita.
Nzira:
Kugadzirira kweTFMPA kunowanzoitwa neakawanda-nhanho maitiro. Imwe nzira yakajairika yekugadzirira ndeyekuita trifluoromethane ine chloromethylbenzene kugadzira 2-chloromethyl-3-(trifluoromethoxy) benzene (CF3CH2OH) uye substrate yekupindura. Zvadaro, iyo substrate yekupindura inobatwa neiyo oxidizing mumiriri kuwana TFMPA.
Zvekuchengetedza
Kushanda zvisina njodzi kweTFMPA kunofanirwa kutevedzera mirairo yekuchengetedzwa kwerabhoritari. Nekuda kwe acidity yayo uye oxidation, inofanirwa kudzivirira kusangana nezvinhu zvinopisa, organic solvents uye magasi anopisa. Midziyo yekuzvidzivirira yakafanira senge magurovhosi erabhu, magirovhosi uye mbatya dzemurabhoritari dzinofanirwa kupfekwa panguva yekushanda. Panguva imwecheteyo, inofanirwa kushandiswa munzvimbo inofefetera zvakanaka kudzivirira kuunganidzwa kwemagasi anokuvadza.
