Mea Hana Kumukūʻai Maikaʻi Butylal (Dibutoxymethane) CAS: 2568-90-3
Nā huaʻōlelo like
ʻO ka Formaldehyde dibutyl acetal kahi acetal i hoʻohana ʻia i ka hana ʻana i nā resins synthetic, antiseptics, deodorants, a me fungicides. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea hoʻohui wahie e hoʻonui i ka helu octane o ka gasoline a i ʻole ka helu n-cetane o nā wahie diesel a hōʻemi i ka uahi a me nā hoʻokuʻu particulate.
Nā noi o Butylal
- ʻO ka Formaldehyde dibutyl acetal kahi mea hoʻoheheʻe halogen-free a emi iki ka ʻawahia e hiki ke hoʻohana ʻia e hoʻoheheʻe i nā laʻana polyethylene haʻahaʻa-density kalepa (LDPE) e kālailai i ka hoʻolaha kaumaha molekala me ka hoʻohana ʻana i ka gel permeation chromatography (GPC). Hiki ke hoʻohana ʻia ma ke ʻano he reactant e hoʻomākaukau i ka butoxymethyltriphenylphosphonium iodide, kahi i hoʻohana ʻia no ka homologation kalapona a ma ke ʻano he kikowaena koʻikoʻi pono i ka synthesis organik.
- Hoʻomākaukau: Hoʻomoʻa ʻia kahi ʻōmole me 15 gm (0.5 mole) o ka paraformaldehyde, 74 gm (1.0 mole) o ka η-butyl alcohol, a me 2.0 gm o ka ferric chloride anhydrous no 10 hola. Hoʻolei ʻia ka papa lalo o 3-4 ml o ka mea a laila hoʻohui ʻia he 50 ml o ka 10% sodium carbonate solution e wehe i ka ferric chloride ma ke ʻano he ferric hydroxide. Hoʻoluliluli ʻia ka huahana me ka hui ʻana o 40 ml o 20% hydrogen peroxide a me 5 ml o 10% sodium carbonate solution ma 45°C i mea e wehe ai i kekahi aldehyde i koe. Holoi ʻia hoʻi ka huahana me ka wai, hoʻomaloʻo ʻia, a hoʻoheheʻe ʻia mai ka sodium metal keu e loaʻa ai he 62 gm (78%).
