Nhanganyaya

Hunhu:

1. Pyridine imvura isina ruvara uye ine kunhuhwirira kwakasimba kwebenzene.

2. Iine nzvimbo yepamusoro yekubikira uye kusagadzikana, uye inogona kunyungudutswa mune zvakasiyana-siyana zveorganic solvents, asi zvakaoma kunyunguduka mumvura.

3. Pyridine chinhu chealkaline chinoderedza maasidhi mumvura.

4. Pyridine inogona kupinda hydrogen bonding nemishonga yakawanda.

 

Shandisa:

1. Pyridine inowanzoshandiswa sechinhu chinonyungudutsa mu organic synthesis reactions, uye ine high solubility kune akawanda organic compounds.

2. Pyridine inewo mashandisirwo mukugadzirwa kwemishonga yezvipembenene, yakadai sekugadzirwa kwefungicides nemishonga yezvipembenene.

 

Nzira:

1. Pyridine inogona kugadzirirwa nemhando dzakasiyana-siyana dzekugadzirisa nzira, iyo inowanzoshandiswa iyo inowanikwa nekuderedza hydrogenation yepyridinexone.

2. Dzimwe nzira dzakajairika dzekugadzirira dzinosanganisira kushandiswa kweammonia uye aldehyde compounds, kuwedzera kwekuita kwe cyclohexene uye nitrogen, nezvimwewo.

 

Zvekuchengetedza

1. Pyridine is organic solvent uye ine kumwe kusagadzikana. Attention inofanira kubhadharwa kune yakanyatsofefeterwa murabhoritari mamiriro kana uchishandisa kudzivirira inhalation of overdose.

2. Pyridine inogumbura uye inogona kukuvadza maziso, ganda, uye nzira yekufema. Midziyo yekudzivirira yakakodzera, kusanganisira magurovhosi, magirazi, uye masks ekudzivirira, inofanirwa kupfekwa panguva yekushanda.

3. Nzira dzakakodzera dzekudzivirira uye dzekudzivirira dzinodiwa kune vanhu vakave vakatarisana nepyridine kwenguva refu.
