Formaldehyde dibutyl acetal wani acetal ne da ake amfani da shi wajen kera resin roba, magungunan kashe ƙwayoyin cuta, magungunan deodorants, da kuma magungunan kashe ƙwayoyin cuta. Haka kuma ana amfani da shi azaman ƙarin mai don ƙara yawan man fetur na octane ko adadin man dizal na n-cetane da kuma rage hayaki da barbashi masu gurbata muhalli.
Amfani da Butylal
- Formaldehyde dibutyl acetal wani sinadari ne mai narkewa wanda ba shi da halogen kuma ba shi da guba wanda za a iya amfani da shi don narke samfuran polyethylene mai ƙarancin yawa na kasuwanci (LDPE) don nazarin rarraba nauyin kwayoyin halitta ta amfani da gel permeation chromatography (GPC). Hakanan ana iya amfani da shi azaman mai amsawa don shirya butoxymethyltriphenylphosphonium iodide, wanda ake amfani da shi don haɗin carbon da kuma azaman maɓalli mai mahimmanci a cikin haɗakar kwayoyin halitta.
- Shiri: Ana zuba kwalba mai ɗauke da gram 15 (mole 0.5) na paraformaldehyde, gram 74 (mole 1.0) na η-butyl alcohol, da gram 2.0 na anhydrous ferric chloride na tsawon awanni 10. Ana zubar da ƙasan Layer na 3-4 ml na abu sannan a ƙara 50 ml na 10% na sodium carbonate na ruwa don cire ferric chloride a matsayin ferric hydroxide. Ana girgiza samfurin da cakuda 40 ml na 20% hydrogen peroxide da 5 ml na 10% sodium carbonate a 45°C don cire duk wani aldehyde da ya rage. Haka kuma ana wanke samfurin da ruwa, a busar da shi, sannan a tace shi daga ƙarfen sodium mai yawa don samun gram 62 (78%).
