Awọn itumọ ọrọ sisọ

Formaldehyde dibutyl acetal jẹ acetal ti a lo ninu iṣelọpọ awọn resini sintetiki, awọn apakokoro, awọn deodorants, ati awọn fungicides.O tun lo bi afikun idana lati mu nọmba octane ti petirolu pọ si tabi nọmba n-cetane ti awọn epo diesel ati dinku ẹfin ati awọn itujade particulate.

Awọn ohun elo ti Butylal

  1. Formaldehyde dibutyl acetal jẹ halogen-ọfẹ ati epo ti ko ni majele ti o le ṣee lo lati solubilize awọn ayẹwo polyethylene iwuwo kekere ti iṣowo (LDPE) lati ṣe itupalẹ pinpin iwuwo molikula nipa lilo chromatography gel permeation (GPC).O tun le ṣee lo bi reactant lati mura butoxymethyltriphenylphosphonium iodide, eyi ti o ti lo fun erogba homologation ati ki o tun bi a wulo bọtini agbedemeji si ni Organic kolaginni.
  2. Igbaradi: Ago ti o ni 15 gm (0.5 mole) ti paraformaldehyde, 74 gm (1.0 mole) ti oti η-butyl, ati 2.0 gm ti anhydrous ferric kiloraidi ti wa ni refluxed fun wakati 10.Ipele isalẹ ti 3-4 milimita ti ohun elo jẹ asonu ati lẹhinna 50 milimita ti 10% ojutu iṣuu soda carbonate olomi ti wa ni afikun lati yọ kiloraidi ferric kuro bi ferric hydroxide.Ọja naa ti mì pẹlu adalu 40 milimita ti 20% hydrogen peroxide ati 5 milimita ti 10% iṣuu soda carbonate ojutu ni 45 ° C lati yọkuro eyikeyi aldehyde ti o ku.A tun fọ ọja naa pẹlu omi, ti gbẹ, ati distilled lati inu irin iṣuu soda ti o pọju lati ni 62 gm (78%).
