Nhanganyaya
Methyl trifluoromethylbenzoate. Inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza kwekomboni:
Hunhu:
Chitarisiko: Methyl trifluoromethylbenzoate imvura isina ruvara uye yakajeka.
Solubility: Inonyungudika mune zvakawanda organic solvents senge ethanol, dimethylformamide, uye chloroform.
Kugadzikana kwekushisa kwepamusoro: kugadzikana pakupisa kwepamusoro, kwete nyore kuora.
Shandisa:
Methyl trifluoromethylbenzoate inowanzoshandiswa sechinhu chakakosha chepakati mune organic synthesis.
Inogona zvakare kushandiswa kugadzira ekuwedzera mumapolymers uye machira.
Iine simba rekusimudzira zvirimwa, uye inoshandiswawo mumunda wekurima.
Nzira:
Methyl trifluoromethylbenzoate inonyanya kuumbwa nefluorination yemethyl benzoate uye trifluorocarboxylic acid. Iyi nzira inowanzoitwa pane yakaderera tembiricha kudzivirira kuitika kwemaside reaction. Mushure mekuita, chigadzirwa chakachena chinowanikwa kuburikidza nekuita distillation uye kucheneswa.
Zvekuchengetedza
Methyl trifluoromethylbenzoate imvura inopisa uye inofanira kuchengetedzwa kure nemirazvo yakazaruka uye kupisa kwakanyanya.
Kubata ganda nemaziso kunogona kukonzera kusvotwa, uye kungwarira kunofanirwa kutorwa kushandisa midziyo yekuzvidzivirira yakadai semagirovhosi nemagirovhosi.
Dzivisa kusangana nemaoxidants uye akasimba asidhi panguva yekushandiswa uye kuchengetedza kudzivirira kuitika kwekuita kwengozi.
Kuraswa kwemarara kunofanirwa kutevedza mitemo nemirau yenzvimbo, uye hakufanirwe kuraswa paunoda.
Kazhinji, methyl trifluoromethylbenzoate chinhu chakakosha chepakati, chinoshandiswa zvakanyanya muminda yemishonga, yemakemikari uye yekurima. Panguva yekushandiswa, kutarisisa kunofanirwa kubhadharwa kune yakachengeteka kushanda kuti udzivise kuita kwakashata nemamwe makemikari zvinhu.
