Umenzi Ixabiso Elihle I-Butylal (Dibutoxymethane) CAS: 2568-90-3
Izithethantonye
I-Formaldehyde dibutyl acetal yi-acetal esetyenziswa ekwenzeni ii-synthetic resins, ii-antiseptics, ii-deodorants, kunye ne-fungicides. Ikwasetyenziswa njenge-fuel additive ukwandisa inani le-octane yepetroli okanye inani le-n-cetane lamafutha edizili kunye nokunciphisa umsi kunye nokukhutshwa kwee-particles.
Ukusetyenziswa kweButylal
- I-Formaldehyde dibutyl acetal sisinyibilikisi esingena-halogen kwaye esingenatyhefu kangako esinokusetyenziselwa ukunyibilikisa iisampulu ze-polyethylene ephantsi-yoxinano (LDPE) zorhwebo ukuhlalutya ukusasazwa kobunzima be-molecular kusetyenziswa i-gel permeation chromatography (GPC). Ingasetyenziswa njenge-reactant ukulungiselela i-butoxymethyltriphenylphosphonium iodide, esetyenziselwa i-carbon homologation kwaye ikwasetyenziswa njengesixhobo esibalulekileyo esiphakathi kwi-organic synthesis.
- Ukulungiselela: Iflaski equlethe i-15 gm (0.5 mole) ye-paraformaldehyde, i-74 gm (1.0 mole) ye-η-butyl alcohol, kunye ne-2.0 gm ye-anhydrous ferric chloride iyahlanjululwa kangangeeyure ezili-10. Umaleko ongezantsi we-3-4 ml yezinto uyalahlwa uze emva koko kongezwe i-50 ml yesisombululo se-10% sodium carbonate ukususa i-ferric chloride njenge-ferric hydroxide. Imveliso iyashukunyiswa ngomxube we-40 ml ye-20% hydrogen peroxide kunye ne-5 ml yesisombululo se-10% sodium carbonate kwi-45°C ukuze kususwe nayiphi na i-aldehyde eseleyo. Imveliso ihlanjwa ngamanzi, yomiswe, kwaye ihluzwe kwi-sodium metal engaphezulu ukuze ifumane i-62 gm (78%).
