Wopanga Mtengo Wabwino Butylal (Dibutoxymethane) CAS: 2568-90-3
Mawu ofanana ndi mawu
Formaldehyde dibutyl acetal ndi acetal yomwe imagwiritsidwa ntchito popanga utomoni wopangira, antiseptics, deodorants, ndi fungicides.Amagwiritsidwanso ntchito ngati mafuta owonjezera kuti awonjezere nambala ya octane ya petulo kapena n-cetane nambala yamafuta a dizilo ndikuchepetsa utsi ndi tinthu tating'onoting'ono.
Ntchito za Butilal
- Formaldehyde dibutyl acetal ndi zosungunulira zopanda halogen komanso zopanda poizoni zomwe zitha kugwiritsidwa ntchito kusungunula zitsanzo zamalonda za polyethylene (LDPE) kuti aunike kugawa kwa maselo pogwiritsa ntchito gel permeation chromatography (GPC).Angagwiritsidwenso ntchito ngati reactant kukonzekera butoxymethyltriphenylphosphonium ayodini, amene ntchito mpweya homologation komanso monga zothandiza kiyi wapakatikati mu kaphatikizidwe organic.
- Kukonzekera: Botolo lomwe lili ndi 15 gm (0.5 mole) ya paraformaldehyde, 74 gm (1.0 mole) ya η-butyl mowa, ndi 2.0 gm ya anhydrous ferric chloride imasinthidwa kwa 10 hr.M'munsi wosanjikiza wa 3-4 ml ya zinthu amatayidwa ndiyeno 50 ml ya 10% amadzimadzi sodium carbonate njira anawonjezera kuchotsa ferric kolorayidi monga ferric hydroxide.Mankhwalawa amagwedezeka ndi 40 ml ya 20% hydrogen peroxide ndi 5 ml ya 10% sodium carbonate solution pa 45 ° C kuti achotse aldehyde yotsala.Chogulitsacho chimatsukidwanso ndi madzi, zouma, ndi kusungunula kuchokera kuzitsulo zochulukirapo za sodium kuti zigule 62 gm (78%).
