Biphenyl;Phenylbenzene;Diphenyl (CAS#92-52-4)
92-52-4Intshayelelo: Ukuqonda ukubaluleka kwayo
Kwinkalo yekhemistri, ukuchongwa kweekhompawundi kubalulekile kuphando, uphuhliso, kunye nokusetyenziswa kumashishini ahlukeneyo. Enye yeekhompawundi sisichongi imichiza92-52-4. Eli nani likhethekileyo liyinxalenye yobhaliso lweNkonzo yeeNkozo zeMichiza, enika isichongi samanani esisodwa kwikhemikhali nganye, ivumela unxibelelwano olulula nonxibelelwano phakathi kwezazinzulu nabaphandi.
Ikhompawundi enxulumene neI-CAS 92-52-4ibizwa ngokuba yi-2,4-dichlorobenzoic acid (2,4-D). Lo mchiza usetyenziswa kakhulu kwezolimo ukulawula ukhula lwamagqabi abanzi kwizityalo ezahlukeneyo eziquka iinkozo, imifuno, kunye namadlelo. Ukusebenza kwayo kunye nokukhetha kwayo kwenza kube lukhetho oludumileyo kumafama kunye neengcali zezolimo.
Indlela yokusebenza ye-2,4-D kukulinganisa isomers zehomoni yezityalo zendalo kunye nokuphazamisa iipateni eziqhelekileyo zokukhula kwezityalo ezinovakalelo. Oku kunokukhokelela ekukhuleni okungalawulekiyo, kuze ekugqibeleni kubangele ukufa kokhula ekujoliswe kulo, kushiye ingca nezinye izityalo zingachaphazeleki noko. Isakhono sale khompawundi ukujolisa kwiintlobo ezithile zezityalo kwenza ukuba ibe yinxalenye ephambili yezicwangciso zokulawula ukhula.
Nangona kunjalo, ukusetyenziswa kwe-2,4-D ayikho ngaphandle kwengxabano. Iinkxalabo malunga nefuthe layo lokusingqongileyo kunye neengozi zempilo ezinokuthi zikhokelele kwiingxoxo eziqhubekayo malunga nokhuseleko lwayo. Amagunya alawulayo esizwe aseke izikhokelo kunye nezithintelo zokusetyenziswa kwawo ukunciphisa le mingcipheko. Njengoko uphando luqhubeka, ukuqonda impembelelo ye-2,4-D kwi-ecosystems kunye nempilo yabantu ihlala iyindawo ebalulekileyo yophando.
Isishwankathelo,I-CAS 92-52-4yinxalenye ebalulekileyo kwezolimo. Ukuqonda ubunjani bayo, ukusetyenziswa kwayo, kunye neempembelelo zayo kubalulekile ekusetyenzisweni ngenkathalo kunye nolawulo lwezenzo zezolimo. Ngophuhliso lolwazi kwi-chemistry kunye nesayensi yokusingqongileyo, indima ye-compounds efana ne-2,4-D iya kuqhubeka nokuguquka, ukubumba ikamva lezolimo ezizinzileyo.
