Nhanganyaya
3-Pyridine formaldehyde. Izvi zvinotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye3-pyridine formaldehyde:
Hunhu:
- Kuonekwa: 3-pyridine formaldehyde imvura isina ruvara kana chena crystal.
- Solubility: Inonyungudika mune yakawanda organic solvents senge ethanol uye chloroform.
Shandisa:
- Synthetic kushandiswa: 3-pyridine formaldehyde inowanzoshandiswa seyakagadzirwa, yepakati mune organic synthesis uye mbishi zvinhu.
Nzira:
- 3-Pyridine formaldehyde inogona kugadzirirwa neN-oxidation yepyridine. Imwe nzira inowanzoshandiswa ndeyekuita pyridine ine oxidizing agent yakadai se benzoyl peroxide kana hydrogen peroxide kuti ibudise 3-pyridine formaldehyde.
Zvekuchengetedza
- Aya anotevera ekuchengetedza ekuchengetedza anofanirwa kuverengerwa kana uchishandisa nekuchengetedza 3-pyridine formaldehyde:
- Dzivisa kubata neganda uye kudzivirira kufemesa kana kupinza musanganiswa.
- Pfeka magurovhosi emakemikari uye maziso ekudzivirira paunenge uchishandisa.
-Shandisa munzvimbo inofefetera zvakanaka uye dzivirira moto kana tembiricha yakakwira.
- Paunenge uchichengetedza, inofanira kuchengetwa yakavharwa zvakasimba, kure nemoto uye zvinhu zvinopisa.
- Paunenge uchishandisa uye kubata 3-pyridine formaldehyde, tevera akakodzera kuchengetedza maitiro ekushandisa uye matanho ekudzivirira ega.
