| Kufotokozera Zachitetezo | S36/37/39 - Valani zovala zodzitchinjiriza zoyenera, magolovesi ndi chitetezo chamaso / kumaso. S38 - Ngati mulibe mpweya wokwanira, valani zida zoyenera zopumira. S45 - Pakachitika ngozi kapena ngati simukumva bwino, funsani upangiri wachipatala nthawi yomweyo (onetsani chizindikirocho ngati kuli kotheka.) S61 - Pewani kumasulidwa ku chilengedwe. Onani malangizo apadera / mapepala achitetezo. S28A - S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S28 - Mukakhudza khungu, sambani nthawi yomweyo ndi sopo wambiri. S24/25 - Pewani kukhudzana ndi khungu ndi maso. S22 - Osapumira fumbi. S36/37 - Valani zovala zoyenera zodzitchinjiriza ndi magolovesi. S16 - Khalani kutali ndi magwero oyatsira. S7 - Sungani chidebe chotsekedwa mwamphamvu. |

Mawu Oyamba
Ubwino:
1. Pyridine ndi madzi opanda mtundu okhala ndi fungo lamphamvu la benzene.
2. Ili ndi malo otentha kwambiri komanso osasunthika, ndipo imatha kusungunuka m'mitundu yosiyanasiyana ya organic solvents, koma ndizovuta kusungunuka m'madzi.
3. Pyridine ndi mankhwala amchere omwe amalepheretsa ma asidi m'madzi.
4. Pyridine ikhoza kugwirizanitsa ndi hydrogen bonding ndi mankhwala ambiri.
Gwiritsani ntchito:
1. Pyridine nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira mu organic synthesis reactions, ndipo imakhala ndi kusungunuka kwakukulu kwamagulu ambiri achilengedwe.
2. Pyridine alinso ntchito mu synthesis wa mankhwala ophera tizilombo, monga synthesis wa fungicides ndi mankhwala ophera tizilombo.
Njira:
1. Pyridine ikhoza kukonzedwa ndi mitundu yosiyanasiyana ya kaphatikizidwe, yomwe imagwiritsidwa ntchito kwambiri ndi hydrogenation kuchepetsa pyridinexone.
2. Njira zina zokonzekera zodziwika bwino zimaphatikizapo kugwiritsa ntchito mankhwala a ammonia ndi aldehyde, kuwonjezereka kwa cyclohexene ndi nitrogen, etc.
Zambiri Zachitetezo:
1. Pyridine ndi organic solvent ndipo ali ndi kusakhazikika kwina. Chisamaliro ayenera kulipidwa kuti bwino podutsa mpweya zasayansi zinthu pamene ntchito kupewa inhalation wa bongo.
2. Pyridine imakwiyitsa ndipo ikhoza kuwononga maso, khungu, ndi kupuma. Zida zodzitetezera zoyenera, kuphatikiza magolovesi, magalasi, ndi zobvala zodzitetezera, ziyenera kuvalidwa panthawi yogwira ntchito.
3. Njira zoyenera zotetezera ndi zowongolera ndizofunikira kwa anthu omwe akhala akukumana ndi pyridine kwa nthawi yaitali.
