Soo saaraha Qiimaha Wanaagsan Butylal (Dibutoxymethane) CAS: 2568-90-3

sharaxaad gaaban:

Butylal (Dibutoxymethane) waa dareere aan halogen-la'aan ahayn oo sun yar oo loo isticmaali karo in lagu milmo shaybaarada cufnaanta hoose ee polyetylen (LDPE) si loo falanqeeyo qaybinta miisaanka kelli iyadoo la isticmaalayo gel permeation chromatography (GPC).Butylal (Dibutoxymethane) ayaa sidoo kale loo isticmaali karaa falcelin ahaan si loogu diyaariyo butoxymethyltriphenylphosphonium iodide.Butylal (Dibutoxymethane) waxaa loo isticmaalaa isku-dhafka kaarboonka iyo sidoo kale dhexdhexaad muhiim ah oo faa'iido leh ee isku-dhafka dabiiciga ah.

Formaldehyde dibutyl acetal waa acetal loo isticmaalo soo saarida resins synthetic, jeermiska jeermiska, carfiyeyaasha, iyo fungicides.Waxa kale oo loo isticmaalaa wax lagu daro shidaalka si loo kordhiyo tirada octane ee gaaska ama tirada n-cetane ee shidaalka naaftada lana yareeyo qiiqa iyo qiiqa sii daaya.

Codsiyada Butylal

Formaldehyde dibutyl acetal waa dareere sun ah oo aan halogen lahayn oo ka yar oo loo isticmaali karo in lagu milmo shaybaarada cufnaanta hoose ee polyetylen (LDPE) si loo falanqeeyo qaybinta miisaanka kelli iyadoo la isticmaalayo gel permeation chromatography (GPC).Waxa kale oo loo isticmaali karaa fal-celis ahaan si loogu diyaariyo butoxymethyltriphenylphosphonium iodide, kaas oo loo isticmaalo isku-dhafka kaarboonka iyo sidoo kale dhexdhexaadiye faa'iido leh oo ku saabsan isku-dhafka organic.
Diyaarinta: Falaash ka kooban 15 gm (0.5 mole) oo paraformaldehyde, 74 gm (1.0 mole) oo ah alkohol η-butyl, iyo 2.0 gm oo ah chloride anhydrous ferric ayaa dib loo soo celinayaa 10 saac.Lakabka hoose ee 3-4 ml oo walax ah ayaa la tuuraa ka dibna 50 ml oo ah 10% xal sodium carbonate aqueous ah ayaa lagu daraa si looga saaro ferric chloride sida ferric hydroxide.Alaabta waxaa lagu ruxayaa isku dar ah 40 ml oo ah 20% hydrogen peroxide iyo 5 ml oo ah 10% sodium carbonate solution at 45°C si meesha looga saaro wixii soo haray aldehyde.Alaabta sidoo kale waxaa lagu dhaqaa biyo, la qalajiyey, lagana nadiifiyaa birta sodium ee xad-dhaafka ah si loo helo 62 gm (78%).
