Isicelo

1. Isetyenziswe njenge-solvent ephilayo, i-reagent analytical, iphinda isetyenziswe kwi-organic synthesis industry, i-chromatography, njl.

2. Isetyenziswa njengento ekrwada yokutsala kunye nokwahlula i-pyridine kunye ne-homologues yayo

3. Iziqholo ezityiwayo.

4. I-Pyridine yimathiriyeli ekrwada ye-herbicides, i-insecticide, i-rubber encedisayo, kunye ne-textile axiliaries.

5. Isetyenziswa kakhulu njengento ekrwada kwishishini, njenge-solvent kunye ne-alcohol denaturant, ekwasetyenziselwa ukuveliswa kwerabha, ipeyinti, i-resin kunye ne-corrosion inhibitors, njl.

6. I-Pyridine ingasetyenziselwa njenge-denaturant kunye ne-ejenti yokudaya kwishishini.

Iphakheji

I-1 kg/ibhegi okanye i-25 kg/igubu okanye i-50 kg/igubu okanye ngokweemfuno zabathengi.

Malunga nezoThutho

1. Sinokunikezela ngeentlobo ezahlukeneyo zothutho ngokuxhomekeke kwiimfuno zabathengi bethu.
2. Ngamanani amancinci, sinokuthumela ngeenqwelo zomoya okanye ngamazwe ngamazwe, njengeFedEx, DHL, TNT, EMS, kunye neendlela ezikhethekileyo zothutho lwamazwe ngamazwe.
3. Ngobungakanani obukhulu, sinokuthumela ngolwandle kwi-port ekhethiweyo.
4. Ukongezelela, sinokubonelela ngeenkonzo ezikhethekileyo ngokweemfuno zabathengi bethu kunye neempawu zeemveliso zabo.

Ugcino

1. Gcina kwindawo epholileyo nengena umoya. Zigcine kude nomlilo kunye nemithombo yobushushu. Ubushushu bokugcina akufunekanga budlule kwi-30°C.

2. Kufuneka igcinwe ngokwahlukileyo kwi-oxidants, i-acids, kunye neekhemikhali ezidliwayo, kwaye ugweme ukugcinwa okuxubileyo. Sebenzisa izibane ezingagqabhukiyo kunye nezixhobo zokungenisa umoya.

3. Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezivelisa ngokulula iintlantsi.

4. Indawo yokugcina kufuneka ixhotywe ngokuvuza kwezixhobo zonyango olungxamisekileyo kunye nezixhobo ezifanelekileyo zokugcina.

Uzinzo

1. Akukho ukubola phantsi kobushushu obuqhelekileyo kunye noxinzelelo. Ukuthintela ukudibana ne-acids, i-oxidants eyomeleleyo, kunye ne-chloroform. Izikhongozeli zobhedu akufunekanga zisetyenziswe. Kuphephe ukuyigcina ngeeoksijini ezinamandla njengeperoxides kunye nenitric acid.

2. I-Pyridine izinzile kwi-oxidants kwaye ayixutywanga yi-nitric acid, i-chromium oxide, i-potassium permanganate, njl., ngoko ingasetyenziselwa njenge-solvent kwi-oxidation reaction kunye ne-permanganate. Indima ye-hydrogen peroxide okanye i-peracid iba yi-N-oxide (C5H5NO).

3. Kunzima ukuba i-pyridine ingene kwi-electrophilic substitution reaction, kwaye i-reaction kaFriedel Crafts ayinakwenzeka. Ngexesha le-nitration, ukushisa okuphezulu kwe-300 ° C kuyadingeka ukufumana i-3-nitropyridine, kwaye isivuno siphantsi. Kodwa ityekele kwi-nucleophilic substitution reaction. Ngokomzekelo, nge-sodium amide ukuvelisa i-2-aminopyridine. Xa i-platinum okanye i-alkali isetyenziswe njenge-catalyst yokusebenzisana namanzi anzima, i-hydrogen yesibini ye-pyridine inokutshintshwa kunye ne-hydrogen enzima.
