Ngwa nke Butylal

Formaldehyde dibutyl acetal bụ ihe mgbaze na-enweghị halogen na nke na-adịghị egbu egbu nke enwere ike iji mee ka ihe atụ nke polyethylene dị ala (LDPE) dị ala iji nyochaa nkesa ịdị arọ molecular site na iji gel permeation chromatography (GPC).Enwere ike iji ya dị ka onye na-emeghachi omume iji kwadebe butoxymethyltriphenylphosphonium iodide, nke a na-eji maka carbon homologation nakwa dị ka isi ihe bara uru na njikọ organic.
Nkwadebe: Otu iko nwere 15 gm (0.5 mole) nke paraformaldehyde, 74 gm (1.0 mole) nke mmanya η-butyl, na 2.0 gm nke anhydrous ferric chloride na-emegharị maka awa 10.A na-atụfu akwa oyi akwa nke 3-4 ml wee tinye 50 ml nke 10% mmiri sodium carbonate ngwọta iji wepụ ferric chloride dị ka ferric hydroxide.A na-amanye ngwaahịa ahụ na ngwakọta nke 40 ml nke 20% hydrogen peroxide na 5 ml nke 10% sodium carbonate solution na 45 Celsius C iji wepụ aldehyde ọ bụla fọdụrụnụ.A na-ejikwa mmiri na-asa ngwaahịa a, akpọnwụọ ma kpochaa ya site na oke sodium metal iji nweta 62 gm (78%).
