Chaw Tsim Khoom Zoo Nqe Butylal (Dibutoxymethane) CAS: 2568-90-3
Cov lus txhais
Formaldehyde dibutyl acetal yog ib qho acetal siv rau hauv kev tsim cov resins hluavtaws, tshuaj tua kab mob, tshuaj deodorants, thiab fungicides. Nws kuj tseem siv ua cov roj ntxiv rau kom nce tus lej octane ntawm roj av lossis tus lej n-cetane ntawm roj diesel thiab txo cov pa luam yeeb thiab cov pa phem.
Cov ntawv thov ntawm Butylal
- Formaldehyde dibutyl acetal yog ib yam tshuaj uas tsis muaj halogen thiab tsis muaj tshuaj lom ntau uas siv tau los yaj cov qauv polyethylene qis (LDPE) uas muag hauv khw kom siv gel permeation chromatography (GPC). Nws kuj siv tau ua ib yam tshuaj reactant los npaj butoxymethyltriphenylphosphonium iodide, uas siv rau kev sib xyaw cov pa roj carbon thiab tseem yog ib yam khoom siv tseem ceeb hauv kev tsim cov organic.
- 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 raug refluxed rau 10 teev. Txheej qis ntawm 3-4 ml ntawm cov khoom raug pov tseg thiab tom qab ntawd 50 ml ntawm 10% aqueous sodium carbonate kua raug ntxiv rau kom tshem tawm ferric chloride ua ferric hydroxide. Cov khoom raug co nrog sib tov ntawm 40 ml ntawm 20% hydrogen peroxide thiab 5 ml ntawm 10% sodium carbonate kua ntawm 45 ° C kom tshem tawm cov aldehyde seem. Cov khoom kuj tseem ntxuav nrog dej, ziab, thiab distilled ntawm cov sodium hlau ntau dhau kom muaj 62 gm (78%).
