Soo-saare Qiimo Fiican Butylal (Dibutoxymethane) CAS: 2568-90-3
Erayo isku mid ah
Formaldehyde dibutyl acetal waa acetal loo isticmaalo soo saarista resins-ka synthetic-ga, jeermiska dila, carfistayaasha, iyo fungicides-ka. Waxa kale oo loo isticmaalaa sidii wax lagu daro shidaalka si loo kordhiyo tirada octane-ka ee shidaalka ama tirada n-cetane ee shidaalka naaftada iyo in la yareeyo qiiqa iyo qiiqa walxaha qarxa.
Isticmaalka Butylal
- Formaldehyde dibutyl acetal waa dareere aan lahayn halogen oo aan sun lahayn oo loo isticmaali karo in lagu milmo muunadaha polyethylene-ka cufnaanta yar ee ganacsiga (LDPE) si loo falanqeeyo qaybinta miisaanka molecular iyadoo la adeegsanayo jel permeation chromatography (GPC). Waxa kale oo loo isticmaali karaa sidii falgal si loo diyaariyo butoxymethyltriphenylphosphonium iodide, kaas oo loo isticmaalo isku-dhafka kaarboonka iyo sidoo kale dhexdhexaad muhiim ah oo waxtar leh oo ku jira isku-darka dabiiciga ah.
- Diyaarinta: Dhalo ka kooban 15 gm (0.5 mole) oo paraformaldehyde ah, 74 gm (1.0 mole) oo ah alkohol η-butyl ah, iyo 2.0 gm oo ah chloride ferric ah oo aan biyo lahayn ayaa dib loo celinayaa 10 saacadood. Lakabka hoose ee 3-4 ml oo ah walax ayaa la tuurayaa ka dibna 50 ml oo ah 10% xal sodium carbonate ah oo biyo ah ayaa lagu darayaa si looga saaro ferric chloride sida ferric hydroxide. Badeecada waxaa lagu ruxaa isku darka 40 ml oo ah 20% hydrogen peroxide iyo 5 ml oo ah 10% xal sodium carbonate ah heerkul ah 45°C si looga saaro wax kasta oo aldehyde ah oo harsan. Badeecada waxaa sidoo kale lagu dhaqaa biyo, la qalajiyaa, lagana soo saaraa birta sodium xad-dhaafka ah si loo helo 62 gm (78%).
