Kugwiritsa ntchito

1. Amagwiritsidwa ntchito ngati organic solvent, analytical reagent, amagwiritsidwanso ntchito mu organic synthesis industry, chromatography, etc.

2. Amagwiritsidwa ntchito ngati zopangira pochotsa ndi kulekanitsa pyridine ndi ma homologues ake

3. Zonunkhira zodyedwa.

4. Pyridine ndi zopangira mankhwala a herbicides, mankhwala ophera tizilombo, othandizira mphira, ndi nsalu zothandizira.

5. Amagwiritsidwa ntchito makamaka ngati zopangira mu makampani, monga zosungunulira ndi mowa denaturant, amagwiritsidwanso ntchito popanga mphira, utoto, utomoni ndi dzimbiri inhibitors, etc.

6. Pyridine ingagwiritsidwenso ntchito ngati denaturant ndi dyeing wothandizira pamakampani.

Phukusi

1 kg/thumba kapena 25kg/ng'oma kapena 50kg/ng'oma kapena malinga ndi zofuna za makasitomala.

Kusungirako

1. Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino. Khalani kutali ndi gwero la moto ndi kutentha. Kutentha kosungirako sikuyenera kupitirira 30°C.

2. Iyenera kusungidwa mosiyana ndi ma okosijeni, zidulo, ndi mankhwala odyedwa, ndipo pewani kusungidwa kosakanikirana. Gwiritsani ntchito magetsi osaphulika komanso mpweya wabwino.

3. Ndizoletsedwa kugwiritsa ntchito zida zamakina ndi zida zomwe zimatulutsa zopsereza mosavuta.

4. Malo osungiramo zinthu ayenera kukhala ndi zida zowonongeka zowonongeka komanso zosungirako zoyenera.

Kukhazikika

1. Palibe kuwonongeka pansi pa kutentha kwabwino ndi kupanikizika. Letsani kukhudzana ndi ma asidi, ma okosijeni amphamvu, ndi chloroform. Zotengera zamkuwa siziyenera kugwiritsidwa ntchito. Pewani kuzisunga ndi zotulutsa zamphamvu monga peroxides ndi nitric acid.

2. Pyridine ndi wokhazikika kwa okosijeni ndipo si oxidized ndi asidi nitric, chromium okusayidi, potaziyamu permanganate, etc., kotero angagwiritsidwe ntchito monga zosungunulira mu makutidwe ndi okosijeni anachita ndi permanganate. Ntchito ya hydrogen peroxide kapena peracid imakhala N-oxide (C5H5NO).

3. Ndizovuta kuti pyridine iyambe kuchitapo kanthu pa electrophilic substitution reaction, komanso Friedel Crafts reaction sichitika. Panthawi ya nitration, kutentha kwa 300 ° C kumafunika kuti mupeze 3-nitropyridine, ndipo zokolola zimakhala zochepa. Koma sachedwa kuchita nucleophilic m'malo. Mwachitsanzo, ndi sodium amide kupanga 2-aminopyridine. Pamene platinamu kapena alkali amagwiritsidwa ntchito ngati chothandizira kuti agwirizane ndi madzi olemera, hydrogen yachiwiri ya pyridine ikhoza kusinthidwa ndi heavy hydrogen.
