| Inkcazelo yoKhuseleko | S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S39 –Nxiba ukhuseleko lwamehlo / ubuso. |
Intshayelelo
Yikhompawundi ephilayo enefomula C6H5ClFN. Ilulwelo olungenambala olunevumba elikhethekileyo. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
-Imbonakalo: ulwelo olungenambala
-Ivumba: Ivumba elikhethekileyo
-Ubuninzi: 1.36 g/mL
-Indawo yokubilisa: 137-139 ℃
-Indawo yokunyibilika:-4 ℃
-Ukunyibilika: Kuxubene nezinyibilikisi zendalo, phantse ezinganyibilikiyo emanzini.
Sebenzisa:
Isetyenziswa ngokubanzi kwi-organic synthesis kwaye inokusetyenziswa njenge-catalyst okanye i-raw material. Inezicelo ezibalulekileyo kwi-synthesis ye-pesticides, amayeza kunye neekhemikhali, kwaye isetyenziswa ngokuqhelekileyo ekwenzeni i-pesticides, idayi, i-solvents, njl.
Indlela yokuLungiselela: Indlela yokulungiselela ye
inzima ngakumbi. Indlela yokulungiselela ngokubanzi kukufumana i-5-chloro -2-oxo -3-methyl pyridine nge-chloro-propionaldehyde reaction ngokusebenzisa i-pyridine njengento eluhlaza, kwaye ufumane imveliso yokugqibela ngokuphendula kwe-fluorination.
Ulwazi ngoKhuseleko:
Yikhompawundi ephilayo, kwaye ezi zilumkiso zilandelayo zokhuseleko kufuneka ziqwalaselwe xa uyisebenzisa:
-Ubutyhefu bunokubangelwa kukuphefumla, ukudibana okanye ukusela. Ukudibana ngokuthe ngqo kwesikhumba, amehlo kunye ne-mucous membranes kufuneka kugwenywe.
-Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, iiglasi kunye nempahla yokukhusela xa usetyenziswa.
-Kuphephe ukudibana ne-oxidants, i-acids eqinile, iziseko ezinamandla kunye nezinye izinto ukuphepha ukuphendula okungakhuselekanga.
-Xa ukuvuza kwenzeka, amanyathelo afanelekileyo kufuneka athathwe ukucoca ukuvuza kunye nokuphepha ukungena kwi-drain system kunye nokusingqongileyo.
Xa usebenzisa i-compound, thatha amanyathelo okhuseleko ahambelanayo ngokwemeko yangempela kwaye ubhekisele kwiphepha ledatha yokhuseleko lwekhompawundi.
