Umenzi wexabiso eliLungileyo i-Butylal (Dibutoxymethane) CAS: 2568-90-3

inkcazelo emfutshane:

I-Butylal (i-Dibutoxymethane) yi-halogen-free kunye ne-solvent encinci enetyhefu engasetyenziselwa ukunyibilikisa iisampulu ze-polyethylene eziphantsi koxinaniso (LDPE) ukuhlalutya ukusabalalisa ubunzima be-molecular usebenzisa i-gel permeation chromatography (GPC).I-Butylal (i-Dibutoxymethane) ingasetyenziswa njenge-reactant ukulungiselela i-butoxymethyltriphenylphosphonium iodide.I-Butylal (i-Dibutoxymethane) isetyenziselwa i-carbon homologation kunye nanjengesitshixo esibalulekileyo esiphakathi kwi-organic synthesis.

I-Formaldehyde dibutyl acetal yi-acetal esetyenziswa ekwenzeni iireyini zokwenziwa, izibulala-ntsholongwane, izikhupha-vumba, kunye nezibulala-ntsholongwane zokungunda.Ikwasetyenziswa njengezongezo zepetroli ukunyusa inani le-octane yepetroli okanye inani le-n-cetane lamafutha edizili kunye nokunciphisa umsi kunye nokukhutshwa kwe-particle.

Usetyenziso lwe-Butyal

I-Formaldehyde dibutyl acetal yi-halogen-free kunye ne-solvent encinci enetyhefu engasetyenziselwa ukunyibilikisa iisampulu ze-polyethylene eziphantsi koxinano (LDPE) ukuhlalutya ukuhanjiswa kobunzima bemolekyuli kusetyenziswa i-gel permeation chromatography (GPC).Isenokusetyenziswa njenge-reactant ukulungiselela i-butoxymethyltriphenylphosphonium iodide, esetyenziselwa i-carbon homologation kwaye njengesixhobo esibalulekileyo esiphakathi kwi-organic synthesis.
Ukulungiselela: Iflaski equlethe i-15 gm (0.5 mole) yeparaformaldehyde, 74 gm (1.0 imvukuzane) ye-η-butyl alcohol, kunye ne-2.0 gm ye-anhydrous ferric chloride ihlaziywa nge-10 hr.Umaleko osezantsi we-3-4 ml wezinto eziphathekayo ulahlwa kwaye emva koko i-50 ml ye-10% yesisombululo se-sodium carbonate yamanzi yongezwa ukususa i-chloride ye-ferric njenge-ferric hydroxide.Imveliso ishukunyiswa ngomxube we-40 ml ye-20% ye-hydrogen peroxide kunye ne-5 ml ye-10% isisombululo se-sodium carbonate kwi-45 ° C ukwenzela ukususa nayiphi na i-aldehyde eseleyo.Imveliso iphinda ihlanjwe ngamanzi, yomiswe, kwaye idilizwe kwintsimbi ye-sodium engaphezulu ukuze ifikelele kwi-62 gm (78%).
