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

Intengo Enhle Yomkhiqizi I-Butylal (Dibutoxymethane) CAS: 2568-90-3 Isithombe Esivelele

incazelo emfushane:

I-Butylal (i-Dibutoxymethane) iyi-solvent engena-halogen futhi engenabo ubuthi obuncane engasetshenziswa ukuncibilikisa amasampula e-polyethylene ephansi-density (LDPE) yokuhweba ukuze kuhlaziywe ukusatshalaliswa kwesisindo sama-molecule kusetshenziswa i-gel permeation chromatography (GPC). I-Butylal (i-Dibutoxymethane) ingasetshenziswa futhi njenge-reactant ukulungiselela i-butoxymethyltriphenylphosphonium iodide. I-Butylal (i-Dibutoxymethane) isetshenziselwa ukuhlanganiswa kwe-carbon futhi futhi njenge-key intermediate ewusizo ekuhlanganisweni kwezinto eziphilayo.

Amagama afanayo

I-Formaldehyde dibutyl acetal iyi-acetal esetshenziswa ekwenziweni kwama-resin okwenziwa, ama-antiseptic, ama-deodorant, kanye nama-fungicides. Iphinde isetshenziswe njengesithasiselo sikaphethiloli ukwandisa inani le-octane likaphethiloli noma inani le-n-cetane likaphethiloli kadizili kanye nokunciphisa ukukhishwa kwentuthu kanye nezinhlayiya.

Ukusetshenziswa kwe-Butylal

I-Formaldehyde dibutyl acetal iyi-solvent engena-halogen futhi engenabo ubuthi obuncane engasetshenziswa ukuncibilikisa amasampula e-polyethylene ephansi-density (LDPE) yokuhweba ukuze kuhlaziywe ukusatshalaliswa kwesisindo sama-molecule kusetshenziswa i-gel permeation chromatography (GPC). Ingasetshenziswa futhi njenge-reactant ukulungiselela i-butoxymethyltriphenylphosphonium iodide, esetshenziselwa ukuhlanganiswa kwe-carbon kanye nanjengesihluthulelo esiwusizo esiphakathi kokwenziwa kwezinto eziphilayo.
Ukulungiselela: Ibhodlela eliqukethe amagremu angu-15 (0.5 mole) we-paraformaldehyde, amagremu angu-74 (1.0 mole) we-η-butyl alcohol, kanye namagremu angu-2.0 we-ferric chloride engamanzi liyasuswa amahora ayi-10. Ingqimba engezansi ye-3-4 ml yezinto ezisetshenziswayo iyalahlwa bese kufakwa isixazululo se-sodium carbonate esingu-50 ml esingu-10% samanzi ukuze kususwe i-ferric chloride njenge-ferric hydroxide. Umkhiqizo unyakaziswa ngengxube ye-40 ml ye-hydrogen peroxide engu-20% kanye nesisombululo se-sodium carbonate esingu-5 ml esingu-10% ku-45°C ukuze kususwe noma iyiphi i-aldehyde esele. Umkhiqizo uphinde ugezwe ngamanzi, womiswe, bese uhlanzwa kusuka ku-sodium metal eningi ukuze uthole amagremu angu-62 (78%).
