Isticmaal

1. Waxaa loo adeegsaday sidii dareeraha dabiiciga ah, dib-u-habeynta falanqaynta, oo sidoo kale loo adeegsaday warshadaha isku-dhafka dabiiciga ah, koromosiiska, iwm.

2. Waxaa loo adeegsaday sidii ashyaa cayriin oo loogu talagalay soo saarista iyo kala goynta Pyridine iyo is-hoosaysiinta

4. Pyridine waa shey ceyriin ah oo loogu talagalay doog, cayayaanka, sunta cayayaanka, waxyaabaha kuyaala caarada caagga ah, iyo waxyaabaha ku habboon ee dharka lagu dhaqo.

5. Badanaa loo isticmaalo maaddaama ashyaa ka mid ah warshadaha, sida dareeraha qaniinyada iyo aalkolada, oo sidoo kale loo adeegsaday soo saarista caagga, rinjiga, rinji, xakamaynta wasaqda, iwm.

6. Pyridine sidoo kale waxaa loo isticmaali karaa sida wakiilka iyo wakiilka caqabaynta ee warshadaha.

Bakhaar

1. Ku keydi bakhaarka qabow, hawo hawo leh. Ka fogow dabka iyo kuleylka. Heerkulka kaydinta waa inuusan ka badneyn 30 ° C.

2. Waa in lagu kaydiyaa si gooni gooni ah ee aashitada, aashitada, iyo kiimikooyinka la cuni karo, kana fogow kaydinta isku dhafan. Adeegso nalalka qaraxa cad iyo tas-hiilaadka hawo-mareenka.

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

4. Aagga kaydinta waa in lagu qalabeeyaa qalabka daaweynta degdegga ah ee daadashada iyo alaabada kaydinta ee ku habboon.

Xasilloni

1. Ma jiro wax-dhaaf ah oo ku hoos jira heerkulka caadiga ah iyo cadaadiska. Waxay ka mamnuucdaa taabashada aashitada, oxidayaal adag, iyo chloroform. Weelasha naxaas ah waa inaan la istcimaalin. Ka fogow inaad ku keydiso qalab xoog leh sida Veroxie iyo nitric acid.

2. Pyridine-ka waa mid aad u deggan in ka badan ee loo yaqaan 'oxidi' oo aan ku xidhnayn nitric acid, chromium oside, cerm. KPManate, sidaa darteed waxaa loo adeegsan karaa falcelinta oksidatanimada ee ay la socdaan khafiifka. Doorka hydrogen peroxide ama peracin wuxuu noqdaa n-oxide (c5h5no).

3. Way adag tahay in Pyridine in la mari doono falcelinta korantada kontaroolka ah, mana dhicin falcelinta frexsion-ka Friedel Machashka. Inta lagu guda jiro naitration, heerkul sarreeya oo ah 300 ° C ayaa looga baahan yahay inuu helo 3-nitropyradine, oo dhalidda ayaa hooseysa. Laakiin waxay u nugul tahay falcelinta nucleophilic. Tusaale ahaan, leh sodium amides si loo soo saaro 2-Amanopyradine. Marka platinum ama alkali loo istcimaalo sidii wax u dhima si ay ula falgalaan biyo culus, hydrogen-ka labaad ee pyridine waxaa lagu beddeli karaa hydrogen culus.
