Mugadziri Mutengo Wakanaka Butylal (Dibutoxymethane) CAS: 2568-90-3
Mazwi anoreva zvakafanana
Formaldehyde dibutyl acetal iacetal inoshandiswa mukugadzira maresini ekugadzira, mishonga inouraya utachiona, deodorants, uye fungicides. Inoshandiswawo sekuwedzera mafuta kuwedzera huwandu hweoctane yepeturu kana huwandu hwe n-cetane yemafuta edhiziri uye kuderedza utsi netunhu tudiki.
Mashandisirwo eButylal
- Formaldehyde dibutyl acetal chinhu chisina halogen uye chisina chepfu chinogona kushandiswa kunyungudutsa samples dze commercial low-density polyethylene (LDPE) kuongorora kugoverwa kwehuremu hwemamorekuru uchishandisa gel permeation chromatography (GPC). Inogona zvakare kushandiswa se reactant kugadzira butoxymethyltriphenylphosphonium iodide, iyo inoshandiswa pakubatana kwecarbon uye zvakare sekiyi inobatsira pakati pekugadzirwa kweorganic.
- Kugadzirira: Chirongo chine 15 gm (0.5 mole) ye paraformaldehyde, 74 gm (1.0 mole) ye η-butyl alcohol, uye 2.0 gm ye anhydrous ferric chloride zvinodzoserwa kwemaawa gumi. Chikamu chezasi che 3-4 ml yezvinhu zvinoraswa uye 50 ml ye 10% aqueous sodium carbonate solution inowedzerwa kubvisa ferric chloride se ferric hydroxide. Chigadzirwa chinozununguswa nemusanganiswa we 40 ml ye 20% hydrogen peroxide uye 5 ml ye 10% sodium carbonate solution pa 45°C kuitira kubvisa chero aldehyde yasara. Chigadzirwa chinosukwawo nemvura, choomeswa, uye chinonyungudutswa kubva mu sodium metal yakawandisa kuti chiwane 62 gm (78%).
