Synonyms

Formaldehyde dibutyl acetal yog ib qho acetal siv los tsim cov khoom siv hluavtaws, tshuaj tua kab mob, deodorants, thiab fungicides.Nws kuj yog siv los ua ib qho roj ntxiv los ua kom cov roj av octane los yog n-cetane cov roj diesel thiab txo cov pa taws thiab cov pa phem.

Kev siv ntawm Butylal

Formaldehyde dibutyl acetal yog halogen-dawb thiab tsis muaj tshuaj lom cov kuab tshuaj uas yuav siv tau los solubilize coj mus muag low-density polyethylene (LDPE) cov qauv los soj ntsuam molecular hnyav tis siv gel permeation chromatography (GPC).Nws kuj tseem siv tau los ua cov tshuaj reactant los npaj butoxymethyltriphenylphosphonium iodide, uas yog siv rau carbon homologation thiab kuj yog ib qho tseem ceeb tseem ceeb nruab nrab ntawm cov organic synthesis.
Kev npaj: Ib lub raj mis uas muaj 15 gm (0.5 mole) ntawm paraformaldehyde, 74 gm (1.0 mole) ntawm η-butyl cawv, thiab 2.0 gm ntawm anhydrous ferric chloride yog refluxed rau 10 hr.Cov txheej qis ntawm 3-4 ml ntawm cov khoom raug muab pov tseg thiab tom qab ntawd 50 ml ntawm 10% aqueous sodium carbonate tov yog ntxiv kom tshem tawm cov ferric chloride li ferric hydroxide.Cov khoom yog shaken nrog ib tug sib tov ntawm 40 ml ntawm 20% hydrogen peroxide thiab 5 ml ntawm 10% sodium carbonate tov ntawm 45 ° C thiaj li yuav tshem tawm tej seem aldehyde.Cov khoom no kuj tau ntxuav nrog dej, qhuav, thiab distilled los ntawm ntau tshaj sodium hlau kom them 62 gm (78%).
