Isingeniso
I-3,4-Dichloropyridine iyinhlanganisela yemvelo enefomula yamakhemikhali i-C5H3Cl2N. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: uketshezi olungenambala
-Indawo yokuncibilika:-12 ℃
-Indawo yokubilisa: 149-150 ℃
-Ukuminyana: 1.39 g/mL
-Ukunyibilika: Kunokuncibilika okuhle futhi kungancibilika emanzini, otshwaleni nasezincibilikisini ze-ether.
Sebenzisa:
- I-3,4-Dichloropyridine ingasetshenziswa njenge-reagent yamakhemikhali futhi njengento ephakathi ebalulekile ekuhlanganiseni kwezinto eziphilayo.
-Ingasetshenziselwa ukuhlanganisa izinto eziphilayo ezifana nezibulala-zinambuzane, izidakamizwa kanye nodayi.
-Embonini ye-elekthronikhi, iphinde isetshenziswe njengento eluhlaza yezinto zokugqoka kanye nezinto ezibonakalayo.
Indlela Yokulungiselela:
I-3,4-Dichloropyridine ingatholakala ngokusabela kwe-pyridine nge-chlorine. Izimo zokusabela zingalungiswa ngokuya ngemishini kanye nezidingo zelabhorethri ethile.
Ulwazi Lokuphepha:
- 3,4-Dichloropyridine iyinhlanganisela yemvelo ecasulayo futhi okungenzeka ibe nobuthi. Lapho usebenzisa, qaphela ukugwema ukuhogela umhwamuko futhi uthintane nesikhumba, amehlo nolwelwesi lwamafinyila.
-Emsebenzini, kufanele athathe izinyathelo zokuzivikela ezifanele, njengokugqoka amagilavu, izibuko nezingubo zokuzivikela.
-Ngesikhathi sokugcina nokuphatha, gwema umlilo nezinto eziphilayo ukuze ugweme izingozi zomlilo noma ukuqhuma.
-Ngesikhathi sokusebenzisa, landela izinqubo zokusebenza eziphephile futhi uphathe futhi ulahle imfucuza ngokuhambisana nemithetho neziqondiso zamazwe ngamazwe, kazwelonke kanye nezasekhaya.
Sicela uqaphele ukuthi lesi yisingeniso esijwayelekile kuphela se-3,4-Dichloropyridine. Ubunjalo obuthile, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha kudinga ukucutshungulwa futhi kuhlolwe ngokucophelela okukhulu ngokuya ngezimo ezithile zaselabhorethri kanye nezimo zangempela.
