Moetsi oa Theko e Ntle Butylal (Dibutoxymethane) CAS: 2568-90-3
Litlhaloso tse tšoanang
Formaldehyde dibutyl acetal ke acetal e sebelisoang ho etsa li-resin tsa maiketsetso, li-antiseptics, deodorants le fungicides.E boetse e sebelisoa e le tlatsetso ea mafura ho eketsa palo ea octane ea peterole kapa palo ea n-cetane ea mafura a diesel le ho fokotsa mosi le mesi ea likaroloana.
Lisebelisoa tsa Butylal
- Formaldehyde dibutyl acetal ke solvent e se nang halogen ebile e se na chefo e fokolang e ka sebelisoang ho qhibilihisa lisampole tsa khoebo tsa polyethylene (LDPE) ho hlahloba kabo ea boima ba limolek'hule ho sebelisoa gel permeation chromatography (GPC).E ka boela ea sebelisoa e le reactant ho lokisetsa butoxymethyltriphenylphosphonium iodide, e sebelisetsoang carbon homologation hape e le senotlolo sa bohlokoa sa lipakeng ho organic synthesis.
- Boitokisetso: 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 khutlisetsoa morao bakeng sa lihora tse 10.Karolo e ka tlase ea 3-4 ml ea thepa e lahloa, ebe 50 ml ea 10% ea tharollo ea sodium carbonate e eketsoa ho tlosa ferric chloride joalo ka ferric hydroxide.Sehlahisoa se sisinyeha ka motsoako oa 40 ml ea 20% hydrogen peroxide le 5 ml ea 10% sodium carbonate tharollo ka 45 ° C e le ho tlosa aldehyde leha e le efe e setseng.Sehlahisoa se boetse se hlatsuoa ka metsi, se omisitsoe, 'me se tšeloa ka tšepe e feteletseng ea sodium ho reka 62 gm (78%).
