Mawu Oyamba
Methyl trifluoromethylbenzoate. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha pawiri:
Ubwino:
Maonekedwe: Methyl trifluoromethylbenzoate ndi madzi opanda mtundu komanso owoneka bwino.
Kusungunuka: Amasungunuka mu zosungunulira zambiri monga ethanol, dimethylformamide, ndi chloroform.
Kukhazikika kwa kutentha kwakukulu: kukhazikika pa kutentha kwakukulu, kosavuta kuwola.
Gwiritsani ntchito:
Methyl trifluoromethylbenzoate nthawi zambiri amagwiritsidwa ntchito ngati gawo lapakati pakupanga organic.
Itha kugwiritsidwanso ntchito kupanga zowonjezera mu ma polima ndi zokutira.
Zimakhudza kwambiri mbewu, zimagwiritsidwanso ntchito m'munda waulimi.
Njira:
Methyl trifluoromethylbenzoate imapangidwa makamaka ndi fluorination ya methyl benzoate ndi trifluorocarboxylic acid. Izi kawirikawiri ikuchitika pa kutentha otsika kupewa zimachitika mbali zimachitikira. Pambuyo pazimenezi, chinthu choyera chimapezeka kudzera mu distillation ndi kuyeretsedwa.
Zambiri Zachitetezo:
Methyl trifluoromethylbenzoate ndi madzi oyaka moto ndipo ayenera kusungidwa kutali ndi moto wotseguka komanso kutentha kwambiri.
Kukhudza khungu ndi maso kungayambitse kuyabwa, ndipo samalani ndi kugwiritsa ntchito zida zodzitetezera monga magolovesi ndi magalasi.
Pewani kukhudzana ndi ma okosijeni ndi ma asidi amphamvu mukamagwiritsa ntchito ndikusunga kuti mupewe zochitika zowopsa.
Kutaya zinyalala kuyenera kutsata malamulo ndi malamulo a mderalo, ndipo zisatayidwe mwakufuna kwake.
Nthawi zambiri, methyl trifluoromethylbenzoate ndi gawo lofunikira lapakati, lomwe limagwiritsidwa ntchito kwambiri m'minda yamankhwala, mankhwala ndi zaulimi. Mukamagwiritsa ntchito, ndikofunikira kuyang'anira magwiridwe antchito otetezeka kuti mupewe zovuta ndi mankhwala ena.
