2-Cyano-5-methylpyridine (CAS# 1620-77-5)

Ke motsoako oa manyolo o nang le motsoako oa lik'hemik'hale oa C8H7N le mokhoa oa moralo oa CH3-C5H3N (CN). E latelang ke tlhaloso ea thepa, litšebeliso, mekhoa ea ho etsa le tlhahisoleseding ea polokeho:Tlhaho:
1. Ponahalo: metsi a se nang 'mala ho ea mosehla.
2. Ntho e qhibilihang:-11 ℃.
3. Sebaka se belang: 207-210 ℃.
4. Solubility: qhibiliha hanyenyane ka metsing, e qhibilihang ka har'a metsoako ea tlhaho e kang joala le ethers.

Sebelisa:
1. E sebelisoa haholo ho organic synthesis, e ka sebelisoa e le reagent, intermediate kapa catalyst ho kenya letsoho liketsong tse sa tšoaneng, tse kang C-C bond formation reaction, cyanide reaction.
2. E ka kenya letsoho ho kenyelletsoeng ha pyridine, pyridine ketone le metsoako e meng ea lintho tse phelang.
3. E ka boela ea sebelisoa ho chefo e bolaeang likokoanyana, meriana le mafapheng a mang.

Mokhoa:
E ka lokisoa ka tsela e latelang ea maiketsetso:
1. Pyridine e sebetsana le methyl acetic anhydride ho hlahisa 5-methyl pyridine.
2. Etsa 5-picoline ka sodium cyanide tlas'a maemo a alkaline ho hlahisa a.

Lintlha tsa Tšireletseho:
1. Over ke ea metsoako ea manyolo, ho na le chefo e itseng, ka kopo latela mekhoa ea ts'ireletso ea laboratori, ela hloko mehato ea ts'ireletso.
2. Qoba ho kopana le letlalo, mahlo, joalo-joalo Haeba ho na le ho kopana, hlatsoa hang-hang ka metsi a mangata. Haeba ho na le phoso leha e le efe, ka kopo, batla thuso ea bongaka.
3. Ha u le polokelong le ho sebetsaneng le eona, ka kopo qoba mocheso o phahameng, mehloli ea mollo, 'me u boloke sebaka sa ts'ebetso se nang le moea o motle.
4. Mokelikeli o litšila o lokela ho lahloa ho latela melao ea lehae ho qoba tšilafalo ea tikoloho.

Ka kopo hlokomela hore tšebeliso le ho tšoaroa ha lintho tsa lik'hemik'hale li lokela ho latela melao e amehang le mekhoa e sireletsehileng ea ts'ebetso, 'me ho latele litataiso tse nepahetseng tsa ts'ebetso ea laboratori.
