Sumo pfupi
4-Chloro-2-fluorobenzoic acid is an organic compound. Iyi inotevera sumo yezvivakwa zvayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:
Hunhu:
4-Chloro-2-fluorobenzoic acid ikristaro yakasimba, kazhinji isina ruvara kana yero. Haisi-inopisa pakupisa kwekamuri. Iine kunhuhwirira uye inogona kunyungudika mune organic solvents senge methanol, ethanol, methylene chloride, nezvimwe.
Shandisa:
4-Chloro-2-fluorobenzoic acid ine huwandu hwakawanda hwekushandisa muindasitiri yemakemikari. Inowanzoshandiswa sechinhu chekutanga kana chepakati mune organic synthesis. Inogona zvakare kushandiswa sechikafu chekudya kune zvinokonzeresa uye zvemagetsi zvinhu.
Nzira:
4-Chloro-2-fluorobenzoic acid inogona kuwanikwa nekunatswa kwep-fluorobenzoic acid. Kazhinji, hydrogen chloride kana chlorous acid inogona kugadziriswa ne thionyl chloride kana sulfinyl chloride pasi pemamiriro eacidic, inoteverwa nekuita nehydrogen fluoride kuwana 4-chloro-2-fluorobenzoic acid.
Zvekuchengetedza
Kuchengetedza kunotevera kunofanirwa kutorwa kana uchibata 4-chloro-2-fluorobenzoic acid: dzivisa kusangana neganda nemaziso, uye teerera kune matanho ekudzivirira sekupfeka magirazi ekudzivirira uye magirovhosi. Inofanira kuitirwa munzvimbo ine mhepo inofefetera zvakanaka kudzivirira kufema kana kumedza. Dzivisa kusangana nezvinhu zvinopisa uye chengetedza kure nemirazvo yakavhurika kana kupisa kwakanyanya. Inofanirwa kuvharwa zvakasimba kana ichishandiswa kana kuchengetwa uye kure nemaasidhi, mabhesi, uye maoxidants. Muchiitiko chekudonha, matanho akakodzera ekukurumidzira anofanirwa kutorwa, sekutora mvura ine desiccant kana kuichenesa neakakodzera kemikari adsorbent.
