Mashoko anoreva zvakafanana

Formaldehyde dibutyl acetal is acetal inoshandiswa mukugadzira resin, antiseptics, deodorants, uye fungicides.Inoshandiswawo sekuwedzera kwemafuta kuwedzera nhamba yeoctane yepeturu kana n-cetane nhamba yemafuta edhiziri uye kuderedza utsi uye kubudiswa kwezvikamu.

Zvishandiso zveButylal

Formaldehyde dibutyl acetal is a halogen-isina uye ine muchetura munyungudutsa unogona kushandiswa kunyungudutsa masampuli ekutengesa akaderera-density polyethylene (LDPE) kuongorora kugoverwa kwehuremu uchishandisa gel permeation chromatography (GPC).Inogona zvakare kushandiswa seyakagadziriswa kugadzirira butoxymethyltriphenylphosphonium iodide, iyo inoshandiswa kune kabhoni homologation uye zvakare seyakakosha kiyi yepakati mune organic synthesis.
Kugadzirira: Flask ine 15 gm (0.5 mole) yeparaformaldehyde, 74 gm (1.0 mole) ye-η-butyl doro, uye 2.0 gm yeanhydrous ferric chloride inodzokororwa kwemaawa gumi.Iyo yepasi ye3-4 ml yezvinhu inoraswa uye ipapo 50 ml ye10% aqueous sodium carbonate solution inowedzerwa kubvisa ferric chloride se ferric hydroxide.Chigadzirwa chacho chinozununguswa nemusanganiswa we40 ml ye20% hydrogen peroxide uye 5 ml ye10% sodium carbonate solution pa45 ° C kuitira kubvisa chero aldehyde yakasara.Chigadzirwa chacho chinoshambidzwawo nemvura, chakaomeswa, uye chakanyungudutswa kubva kune yakawandisa sodium simbi kuti iwane 62 gm (78%).
