Sodium ethoxide (Sodium ethoxide 20% mhinduro)
| Chemical nature | Upfu hwakachena kana hwero;hygroscopic;inosviba uye inoora pakusangana nemhepo;inoora mumvura ichiita sodium hydroxide uye ethanol;inonyungudika mune absolute ethanol.Inoita zvechisimba ine acids, mvura.Hazvienderani ne chlorinated solvents, unyoro.Inobvisa carbon dioxide kubva mumhepo.Kupisa zvakanyanya. | |
| Applications | Sodium ethoxide inoshandiswa mu organic synthesis ye condensation reactions.Iyo zvakare inokonzeresa mune akawanda organic reactions. Sodium ethoxide, 21% w/w mu ethanol inoshandiswa sehwaro hwakasimba mune organic synthesis.Inowana kushandiswa kwakasiyana siyana kwemakemikari kuita senge condensation, esterification, alkoxylation uye etherifcation.Inobatanidzwa muClaisen condensation, Stobbe reaction uye Wolf-kishner kuderedza.Chinhu chakakosha kutanga zvinhu zve synthesis ye ethyl ester uye diethyl ester ye malonic acid.MuWilliamson ether synthesis, inopindirana ne ethyl bromide kuumba diethyl ether. | |
| Sherufu hupenyu | Zvinoenderana neruzivo rwedu, chigadzirwa chinogona kuchengetwa kwe12mwedzi kubva pazuva rekutumira kana yakachengetwa mumidziyo yakavharwa zvakasimba, yakadzivirirwa kubva kuchiedza nekupisa uye yakachengetwa patembiricha iri pakati pe5 -30°C. | |
