Theko e Ntle ea Moetsi Butylal (Dibutoxymethane) CAS: 2568-90-3
Mantsoe a tšoanang
Formaldehyde dibutyl acetal ke acetal e sebediswang tlhahisong ya di-resin tsa maiketsetso, di-antiseptic, di-deodorant le di-fungicide. E boetse e sebediswa e le sehlomathiso sa mafura ho eketsa palo ya octane ya peterole kapa palo ya n-cetane ya mafura a diesel le ho fokotsa mosi le di-particle mission.
Litšebeliso tsa Butylal
- Formaldehyde dibutyl acetal ke solvent e se nang halogen le e seng chefo e ka sebelisoang ho qhibilihisa disampole tsa polyethylene e tlase-density (LDPE) tsa khoebo ho sekaseka kabo ea boima ba limolek'hule ho sebelisoa gel permeation chromatography (GPC). E ka boela ea sebelisoa e le reactant ho lokisa butoxymethyltriphenylphosphonium iodide, e sebelisetsoang ho homologation ea carbon hape e le senotlolo se thusang sa motsoako oa lintho tse phelang.
- Tokisetso: Botlolo e nang le 15 gm (0.5 mole) ea paraformaldehyde, 74 gm (1.0 mole) ea η-butyl alcohol, le 2.0 gm ea anhydrous ferric chloride e tla khutlisetsoa ka hare ho lihora tse 10. Lera le ka tlase la 3-4 ml ea thepa lea lahloa ebe 50 ml ea tharollo ea sodium carbonate ea metsi ea 10% ea eketsoa ho tlosa ferric chloride e le ferric hydroxide. Sehlahisoa se sisinngoa ka motsoako oa 40 ml ea hydrogen peroxide ea 20% le 5 ml ea tharollo ea sodium carbonate ea 10% ho 45°C ho tlosa aldehyde efe kapa efe e setseng. Sehlahisoa se boetse se hlatsuoa ka metsi, se omisoa, 'me se hloekisitsoe ho tsoa tšepeng e feteletseng ea sodium ho fumana 62 gm (78%).
