Utu Pai a te Kaihanga Butylal (Dibutoxymethane) CAS: 2568-90-3
Ngā kupu taurite
Ko te Formaldehyde dibutyl acetal he acetal e whakamahia ana i roto i te hanga kapia hangai, rongoā paturopi, rongoā whakangawari, me ngā rongoā patu harore. Ka whakamahia hoki hei tāpiri wahie hei whakanui ake i te tau octane o te penehīni, te tau n-cetane rānei o ngā wahie tīhiera, hei whakaiti hoki i ngā tukunga paowa me ngā matūriki.
Ngā tono o te Butylal
- Ko te Formaldehyde dibutyl acetal he whakarewa kore-halogen, he iti ake te paitini, ka taea te whakamahi hei whakarewa i ngā tauira polyethylene iti-kiato arumoni (LDPE) hei tātari i te tohatoha taumaha ngota mā te whakamahi i te chromatography permeation gel (GPC). Ka taea hoki te whakamahi hei matū tauhohenga hei whakarite i te butoxymethyltriphenylphosphonium iodide, e whakamahia ana mō te homologation waro, ā, hei takawaenga matua whai hua hoki i roto i te hanganga rauropi.
- Te Whakarite: Ka whakamahanahia he pounamu kei roto ko te 15 karamu (0.5 mole) o te paraformaldehyde, 74 karamu (1.0 mole) o te waipiro η-butyl, me te 2.0 karamu o te konupora konupora korewai mō te 10 hāora. Ka makahia te paparanga o raro o te 3-4 ml o te rauemi, kātahi ka tāpirihia he 50 ml o te otinga konutai kāponāte wai 10% hei tango i te konupora konupora hei hauwai konupora. Ka rūrūtia te hua ki te ranunga o te 40 ml o te 20% hauwai peroxide me te 5 ml o te otinga konutai kāponāte 10% i te 45°C hei tango i te aldehyde e toe ana. Ka horoia hoki te hua ki te wai, ka whakamarokehia, ka whakamātaohia mai i te konganuku konutai nui kia whiwhi ai i te 62 karamu (78%).
