2-Fluoropyridine-5-carboxaldehyde (CAS# 677728-92-6)

Isingeniso

Kuyinhlanganisela yemvelo enefomula yamangqamuzana i-C6H4FN, eshintshwa ngokwesakhiwo yiqembu le-5-formaldehyde eringini engu-2-fluoropyridine. Okulandelayo incazelo eningiliziwe yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:

Imvelo:

-Ukubukeka: Uketshezi oluphuzi olungenambala noma olukhanyayo.

-I-Solubility: Incibilika kuma-solvents amaningi e-organic, njenge-ethanol, i-acetone, njll.

-Indawo yokuncibilika: cishe -5°C.

-Indawo yokubilisa: mayelana ne-135 ℃.

-Amandla adonsela phansi athile: mayelana ne-1.214g/cm³.

-Okuqukethwe: Ukuhlanzeka kuvame ukuba ngaphezu kwama-95%.

Sebenzisa:

-iwusizo njengento yokuqala noma ephakathi ku-organic synthesis.

-Kuvame ukusetshenziswa emkhakheni wezokwelapha ukulungisa izidakamizwa, njenge-antipsychotics kanye nezidakamizwa ze-antineoplastic.

-I-compound ingasetshenziswa futhi ukulungisa izibulala-zinambuzane, izinzwa, odayi, njll.

Indlela Yokulungiselela:

Kunezindlela ezimbili eziyinhloko zokulungiselela:

1. ukusabela kwe-iodine ye-pyridine ne-cyanide, bese kuba ukusabela kwe-fluorination, futhi ekugcineni wengeze umkhiqizo we-formaldehyde.

2. I-pyridine isabela nge-methane ne-boron trifluoride ukuze yakhe i-2-methylpyridine, khona-ke ukusabela kwe-fluorination kuyenziwa, futhi i-formaldehyde yengezwe ukuze kutholwe i-pyridine.

Ulwazi Lokuphepha:

-Izinga elithile lokucasuka kanye nokugqwala, kufanele ligweme ukuthintana nesikhumba, amehlo kanye nomgudu wokuphefumula.

-Landela izinqubo zokuphepha ezifanele ngesikhathi sokusetshenziswa nokugcinwa.

-Sebenzisa endaweni engenawo umoya futhi ugqoke izinto zokuzivikela ezifanele, njengamagilavu, izibuko nezingubo zokuzivikela.

-Uma uthintana, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.

-Uketshezi kanye nemfucuza kufanele kulahlwe ngokuhambisana nemithetho yendawo.
