Codsiga

1. Loo isticmaalo sida dareere organic, reagent gorfaynta, sidoo kale loo isticmaalo warshadaha synthesis organic, chromatography, iwm.

2. Waxa loo isticmaalaa sida walxo ceeriin ah oo lagu soo saaro laguna kala saaro pyridine iyo homologueskeeda

3. Xawaash la cuni karo.

4. Pyridine waa walxo ceeriin ah oo loogu talagalay herbicides, cayayaanka, kaabayaal caag ah, iyo kaabayaal dhar ah.

5. Inta badan loo isticmaalo sida alaabta ceeriin ee warshadaha, sida dareeraha iyo denaturant aalkolada, sidoo kale loo isticmaalo in wax soo saarka ee caag, rinjiga, resin iyo inhibitors daxalka, iwm.

6. Pyridine waxa kale oo loo isticmaali karaa sida denaturant iyo walaxda midabaynta ee warshadaha.

Xidhmada

1 kg/bac ama 25kg/drum ama 50kg/dubaanka ama sida waafaqsan shuruudaha macaamiisha.

Ku saabsan Gaadiidka

1. Waxaan bixin karnaa noocyo kala duwan oo gaadiid ah iyadoo ku xiran baahida macaamiisheena.
2. Tiro yar, waxaan ku soo rari karnaa diyaarado hawada ama kuwa caalamiga ah, sida FedEx, DHL, TNT, EMS, iyo khadadka kala duwan ee gaadiidka caalamiga ah.
3. Tiro badan, waxaan ku soo rari karnaa badda deked loo qoondeeyay.
4. Intaa waxaa dheer, waxaan ku siin karnaa adeegyo gaar ah iyadoo loo eegayo baahida macaamiisheena iyo sifooyinka alaabadooda.

Kaydinta

1. Ku kaydi bakhaar qabow oo hawo leh.Ka fogow dabka iyo ilaha kulaylka.Heerkulka kaydinta waa inuusan dhaafin 30 ° C.

2. Waa in si gooni ah loo kaydiyaa oksaydhiyeyaasha, acids, iyo kiimikooyinka la cuni karo, lagana fogaado kaydinta isku dhafan.Isticmaal nalalka aan qarxin iyo tas-hiilaadka hawo-siinta.

3. Waa mamnuuc in la isticmaalo qalabka farsamada iyo qalabka si fudud u soo saara dhimbiil.

4. Goobta wax lagu kaydiyo waa in lagu qalabeeyaa qalabka daawaynta degdega ah ee daadsan iyo agab kayd oo ku haboon.

Xasilooni

1. Ma jiro burbur ku jira heerkulka caadiga ah iyo cadaadiska.Mamnuuci xidhiidhka asiidhka, oksaydhiyeyaasha xooggan, iyo chloroform.Weelasha naxaasta ah waa inaan la isticmaalin.Iska ilaali inaad ku kaydiso oksidants xooggan sida peroxides iyo nitric acid.

2. Pyridine waa mid aad u deggan oksidayaasha oo aan oksidheeyn by nitric acid, chromium oxide, potassium permanganate, iwm.Doorka hydrogen peroxide ama peracid wuxuu noqonayaa N-oxide (C5H5NO).

3. Way ku adag tahay pyridine in lagu sameeyo falcelinta beddelka elektaroonigga ah, sidoo kale ma dhacdo falcelinta Friedel Crafts.Inta lagu jiro nitration, heerkul sare oo ah 300 ° C ayaa loo baahan yahay si loo helo 3-nitropyridine, wax-soo-saarkuna wuu hooseeyaa.Laakiin waxay u nugul tahay falcelinta beddelka nucleophilic.Tusaale ahaan, oo leh sodium amide si loo soo saaro 2-aminopyridine.Marka platinum ama alkali loo isticmaalo kicin si loola falgalo biyaha culus, hydrogen-ka labaad ee pyridine waxaa lagu bedeli karaa hydrogen culus.
