Mtengo Wabwino Wopanga Butylal (Dibutoxymethane) CAS: 2568-90-3
Mafanizo ofanana
Formaldehyde dibutyl acetal ndi acetal yomwe imagwiritsidwa ntchito popanga ma resins opangidwa, ma antiseptics, deodorants, ndi fungicides. Imagwiritsidwanso ntchito ngati chowonjezera cha mafuta kuti iwonjezere kuchuluka kwa octane ya mafuta kapena kuchuluka kwa n-cetane ya mafuta a dizilo ndikuchepetsa utsi ndi tinthu tating'onoting'ono tomwe timatulutsa utsi.
Kugwiritsa Ntchito Butylal
- Formaldehyde dibutyl acetal ndi chosungunulira chopanda halogen komanso chopanda poizoni chomwe chingagwiritsidwe ntchito kusungunula zitsanzo za polyethylene yotsika kwambiri (LDPE) kuti ifufuze kugawa kwa molekyulu pogwiritsa ntchito gel permeation chromatography (GPC). Ingagwiritsidwenso ntchito ngati reactant kukonzekera butoxymethyltriphenylphosphonium iodide, yomwe imagwiritsidwa ntchito pophatikizana kwa kaboni komanso ngati kiyi wothandiza pakati pa kapangidwe ka organic.
- Kukonzekera: Botolo lokhala ndi 15 gm (0.5 mole) ya paraformaldehyde, 74 gm (1.0 mole) ya η-butyl alcohol, ndi 2.0 gm ya anhydrous ferric chloride imasungunuka kwa maola 10. Gawo lotsika la 3-4 ml la zinthu limatayidwa kenako 50 ml ya yankho la 10% la sodium carbonate limawonjezedwa kuti lichotse ferric chloride ngati ferric hydroxide. Chogulitsacho chimagwedezeka ndi chisakanizo cha 40 ml ya 20% hydrogen peroxide ndi 5 ml ya yankho la 10% sodium carbonate pa 45°C kuti achotse aldehyde yotsala. Chogulitsacho chimatsukidwanso ndi madzi, chouma, ndikusungunuka kuchokera ku sodium metal yochulukirapo kuti chipeze 62 gm (78%).
