Formaldehyde Dibutyl acetal yog ib qho acetal siv hauv kev tsim cov khoom siv hluavtaws, antiseptics, deodorants, thiab fungicides. Nws tseem siv los ua roj av ntxiv kom ua kom lub oxia tus naj npawb ntawm cov roj av lossis cov pa taws thiab cov pa luam yeeb thiab particulation paug.
Cov ntawv thov ntawm Butylal
- Formaldehyde Dibutyl acetal yog ib qho kev lom zem halogen uas siv tau cov qauv kev lag luam qis dua uas siv cov pa roj solecular (LDPE) Nws kuj tseem siv tau los ua ib qho kev ua kom tau npaj cov butoxymethyltriphenylphosphonium thiab tseem siv rau cov hom pa roj carbon monomally thiab tseem muaj cov khoom tseem ceeb hauv cov organic synthesis.
- Kev npaj: lub flask muaj 15 gm (0.5 gole) ntawm paraformaldehyde, 74 gm (1.0 gm (1.0 gm ntawm anhydrous ferric chloride yog refluxed rau 10 hr. Cov txheej hauv qab ntawm 3-4 ml ntawm cov khoom yog pov tseg thiab tom qab ntawd 50 ml ntawm 10% sopolle carbonate tov cov tshuaj ferric raws li fydric hydroxide. Cov khoom yog shaken nrog kev sib xyaw ntawm 40 ml ntawm 20% hydrogen peroxide thiab 5 ml ntawm 10% Sodium carbonate daws ntawm 45 ° C thiaj li tshem tawm ib qho ntxiv Aldehyde. Cov khoom kuj tseem tau ntxuav nrog dej, qhuav, thiab distilled los ntawm ntau sodium hlau kom muaj 62 gm (78%).
