Tagata Gaosi Tau Lelei Butylal (Dibutoxymethane) CAS: 2568-90-3
Synonyms
Formaldehyde dibutyl acetal o se acetal faʻaaogaina i le gaosiga o resini gaosia, vailaʻau faʻamaʻi, deodorants, ma fungicides.E fa'aaogaina fo'i e fai ma mea fa'aopoopo e fa'aopoopo ai le numera octane o le penisini po'o le numera n-cetane o suau'u tiso ma fa'aitiitia ai le asu ma le asu.
Talosaga a Butylal
- Formaldehyde dibutyl acetal ose vaimea e leai se halogen ma itiiti le oona e mafai ona fa'aogaina e solubilize fa'ata'ita'iga polyethylene (LDPE) fa'apisinisi e su'esu'e le tufaina o le mamafa mole mole e fa'aaoga ai le gel permeation chromatography (GPC).E mafai foi ona faʻaaogaina e avea o se mea faʻafefe e saunia ai butoxymethyltriphenylphosphonium iodide, lea e faʻaaogaina mo le carbon homologation ma faʻapea foʻi ma se mea taua tele i le faʻaogaina o meaola.
- Sauniuniga: O se fagu e iai le 15 gm (0.5 mole) o le paraformaldehyde, 74 gm (1.0 mole) o le η-butyl alcohol, ma le 2.0 gm o le anhydrous ferric chloride e toe fa'afo'i mo le 10 itula.O le vaega pito i lalo o le 3-4 ml o meafaitino e lafoai ona faʻaopoopoina lea o le 50 ml o le 10% aqueous sodium carbonate solution e aveese ai le ferric chloride e pei o le ferric hydroxide.O le oloa e luluina i le faʻafefiloi o le 40 ml o le 20% hydrogen peroxide ma le 5 ml o le 10% sodium carbonate solution i le 45 ° C ina ia mafai ai ona aveese soʻo se aldehyde o totoe.E fufulu fo'i le oloa i le vai, fa'agogo, ma fa'amama mai le u'amea sodium tele e maua ai le 62 gm (78%).
