Nhanganyaya

2-ETHOXY-5-NITROPYRIDINE inosanganiswa nemakemikari ane C8H8N2O3.

 

Zvakasikwa:

2-ETHOXY-5-NITROPYRIDINE ikristaro yeyero yakasimba ine kunhuhwirira kwakasiyana. Iine nzvimbo yekunyunguduka inoita 56-58 madhigirii celsius uye painofashaira ingangoita 297-298 madhigirii celsius. Hazvina kunyungudika mumvura pakupisa kwemazuva ose, asi kunyunguduka mune zvinonyungudutsa zvinokonzerwa nedoro, ether, nezvimwewo. Isanganiswa isina kugadzikana inoora nyore nyore pasi pechiedza, kupisa uye kupisa.

 

Shandisa:

2-ETHOXY-5-NITROPYRIDINE inogona kushandiswa seyakakosha yepakati mune organic synthesis, inoshandiswa zvakanyanya mumakemikari synthesis, mushonga, dhayi nemimwe minda. Semusanganiswa unoshanda wakawanda, unogona kushandiswa kugadzira mamwe makomisheni, akadai semishonga, mishonga yezvipembenene uye dhayi.

 

Nzira:

2-ETHOXY-5-NITROPYRIDINE ine nzira dzakawanda dzekugadzirira, imwe yadzo inowanzoshandiswa nekuita kwe5-chloropyridine uye ethyl alcohol pasi pemamiriro e-alkaline. Matanho chaiwo ekubatanidza anoda zvakadzama kuyedza mashandiro uye ruzivo rwemakemikari, ndokumbirawo uite synthesis maitiro munzvimbo yerabhoritari.

 

Zvekuchengetedza

2-ETHOXY-5-NITROPYRIDINE inogona kukonzera kushatirwa kana yasangana neganda nemaziso, saka zvinodikanwa kupfeka midziyo yekudzivirira yakakodzera panguva yekushanda nekubata. Panguva imwecheteyo, musanganiswa unopisa moto uye unofanirwa kuchengetedzwa kure nemoto uye kupisa kwakanyanya kudzivirira magasi anokuvadza uye mhute. Panguva yekuchengetedza uye kubata, cherechedza maitiro ekuchengetedza akakodzera uye uzvichengete mumidziyo yakavharwa. Muchiitiko chetsaona, ndapota tora matanho akakodzera ekukurumidzira uye tsvaga rubatsiro rwekurapa.
