Umkhiqizi Intengo Enhle I-Butylal (Dibutoxymethane) CAS: 2568-90-3

incazelo emfushane:

I-Butylal (i-Dibutoxymethane) i-solvent-free and less poison solvent engasetshenziswa ukunyibilikisa amasampula e-commercial low-density polyethylene (LDPE) ukuze kuhlaziywe ukusatshalaliswa kwesisindo samangqamuzana kusetshenziswa i-gel permeation chromatography (GPC).I-Butylal (i-Dibutoxymethane) ingasetshenziswa futhi njenge-reactant ukuze kulungiswe i-butoxymethyltriphenylphosphonium iodide.I-Butylal (i-Dibutoxymethane) isetshenziselwa ukuhlanganisa i-carbon homologation futhi futhi njengokhiye owusizo omaphakathi ekuhlanganiseni kwe-organic.

I-CAS: 2568-90-3

Omqondofana

I-Formaldehyde dibutyl acetal iyi-acetal esetshenziswa ekwenzeni ama-synthetic resins, antiseptics, deodorants, kanye nama-fungicides.Ibuye isetshenziswe njengesithasiselo sikaphethiloli ukuze kwandiswe inombolo ye-octane kaphethiloli noma inombolo ye-n-cetane yamafutha edizili futhi kuncishiswe intuthu kanye nokukhishwa kwezinhlayiya.

Izicelo ze-Butyal

I-Formaldehyde dibutyl acetal iyincibilikisi engena-halogen futhi engenabuthi obuncane engasetshenziswa ukunyibilikisa amasampuli e-commercial low-density polyethylene (LDPE) ukuze kuhlaziywe ukusatshalaliswa kwesisindo samangqamuzana kusetshenziswa i-gel permeation chromatography (GPC).Ingasetshenziswa futhi njenge-reactant ukuze kulungiswe i-butoxymethyltriphenylphosphonium iodide, esetshenziselwa i-carbon homologation futhi futhi njengokhiye owusizo ophakathi nendawo ekuhlanganiseni kwe-organic.
Ukulungiselela: I-flask equkethe u-15 gm (0.5 imvukuzane) ye-paraformaldehyde, 74 gm (1.0 imvukuzane) ye-η-butyl alcohol, kanye no-2.0 gm we-anhydrous ferric chloride ishintshwa kabusha amahora angu-10.Ungqimba olungezansi luka-3-4 ml wezinto ezibonakalayo luyalahlwa bese u-50 ml wesisombululo se-aqueous sodium carbonate engu-10% kwengezwa ukuze kukhishwe i-ferric chloride njenge-ferric hydroxide.Umkhiqizo unyakaziswa ngengxube engu-40 ml we-hydrogen peroxide engu-20% kanye no-5 ml wesisombululo se-sodium carbonate esingu-10% ku-45°C ukuze kukhishwe noma iyiphi i-aldehyde esele.Umkhiqizo uphinde ugezwe ngamanzi, womiswe, futhi ugaywe ngensimbi ye-sodium eyeqile ukuze uthenge ama-62 gm (78%).
