monarú barbiturates. |
Ullmhú |
Aigéad clóra-aicéiteach a imoibriú le haigéad cyanoacetic ag baint úsáide as ciainíd sóidiam agus saponification ina dhiaidh sin; Déantar aigéad malónach a eistirú ar deireadh trí dhriogadh azeotrópach le eatánól i beinséin |
Luachanna tairsí blas |
Saintréithe an bhlas ag 50 ppm: milis agus torthúil le nuances úll agus anann. |
Próifíl Sábháilteachta |
Tocsaineach éadrom trí ionghabháil. Greannach craicinn. Leacht indóite nuair a bhíonn sé nochtaithe do theas nó lasair; in ann imoibriú le hábhair ocsaídiúcháin. Chun tine a throid, bain úsáid as uisce chun tine, cúr, CO2, ceimiceán tirim a blaincéad. Nuair a théitear é chun dianscaoilte astaíonn sé deatach acrid agus múch greannach. Féach freisin ESTERS. |
Modhanna Íonaithe |
Má tá sé ró-impure (IR, NMR) téitear an t-eistear (250g) ar folctha gaile ar feadh 36 uair le EtOH iomlán (125mL) agus conc H2SO4 (75mL), ansin driogtar go codánach faoi bhrú laghdaithe. Seachas sin déan é a dhriogadh go codánach faoi bhrú laghdaithe agus bailigh an codán meánach fiuchta seasta. [Beilstein 2 IV 1881.] |
