Biphenyl;Phenylbenzene;Diphenyl (CAS#92-52-4)
92-52-4Mawu Oyamba: Kumvetsa tanthauzo lake
M'munda wa chemistry, kuzindikirika kwa mankhwala ndikofunikira pakufufuza, chitukuko, ndikugwiritsa ntchito m'mafakitale osiyanasiyana. Chimodzi mwa zinthuzo ndi chizindikiritso cha mankhwala92-52-4. Nambala yapaderayi ndi mbali ya kaundula wa Chemical Abstracts Service, yomwe imapereka chizindikiritso cha manambala pamankhwala aliwonse, zomwe zimalola kulumikizana kosavuta komanso kulumikizana pakati pa asayansi ndi ofufuza.
Chigwirizano chogwirizana ndiCAS 92-52-4amatchedwa 2,4-dichlorobenzoic acid (2,4-D). Mankhwala a herbicides amagwiritsidwa ntchito kwambiri paulimi kuletsa udzu wambiri mu mbewu zosiyanasiyana kuphatikiza mbewu, zitsamba, ndi msipu. Kuchita bwino kwake ndi kusankha kumapanga chisankho chodziwika kwa alimi ndi akatswiri a zaulimi.
Kachitidwe ka 2,4-D ndikutengera ma isomers amtundu wachilengedwe ndikusokoneza momwe mbewu zimakulirakulira. Izi zingayambitse kukula kosalamulirika, zomwe zimapangitsa kuti udzu womwe ukukhudzidwawo ufe, kusiya udzu ndi mbewu zina zosakhudzidwa. Kuthekera kwa gululi kutsata mitundu inayake ya zomera kumapangitsa kukhala gawo lalikulu la njira zowononga udzu.
Komabe, kugwiritsa ntchito 2,4-D sikuli kopanda kutsutsana. Kudetsa nkhawa za momwe chilengedwe chimakhudzira komanso kuopsa kwa thanzi lomwe lingakhalepo kwadzetsa mikangano yosalekeza yokhudza chitetezo chake. Akuluakulu oyang'anira dziko akhazikitsa malangizo ndi zoletsa kuti agwiritse ntchito pofuna kuchepetsa zoopsazi. Pomwe kafukufuku akupitilira, kumvetsetsa momwe 2,4-D imakhudzira zachilengedwe komanso thanzi la anthu ndi gawo lofunikira kwambiri lofufuzira.
Powombetsa mkota,CAS 92-52-4ndi chinthu chofunika kwambiri pa ulimi. Kumvetsetsa chikhalidwe chake, kagwiritsidwe ntchito kake, ndi zotsatira zake ndikofunikira pakugwiritsa ntchito moyenera ndikuwongolera njira zaulimi. Ndi chitukuko cha chidziwitso mu chemistry ndi sayansi ya chilengedwe, ntchito yamagulu monga 2,4-D idzapitirizabe kusintha, kupanga tsogolo la ulimi wokhazikika.
