Ko te 1,2-Diformyloxyethane, e mohiotia ana ko te acetoacetaldehyde, te acetate acetaldehyde ranei, he matū matū me te tātai rāpoi C4H6O3.He pūhui acetal kei roto e rua nga roopu formyl (aldehyde) e hono ana ki te ngota hāora pokapū.Ka taea te whakahiato 1,2-Diformyloxyethane ma te tauhohe i te formaldehyde (CH2O) me te acetaldehyde (C2H4O) i te aroaro o te whakakorikori waikawa.He wai kore tae me te kakara hua.Ka taea te whakamahi i te 1,2-Diformyloxyethane hei takawaenga i roto i te whakahiato waro, hei whakarewa, hei reagent ranei i etahi tauhohenga.Ka taea hoki te whakamahi hei kai reka i roto i te umanga kai.Heoi, he mea tino nui ki te hapai i tenei puhui me te tupato i te mea he mura ahi, ka whakapataritari i nga kanohi, kiri me te punaha manawa ki te kore e tika te whakahaere.

Ngā Āhuatanga matū | Wai-ma wai.ka āta whakamarohia, ka whakawātea i te waikawa formic.Wairewa ki te wai, te waipiro me te etera.Ka tahuna. |
Whakamahinga | Nga wai whakawai. |
Whakaahuatanga Whanui | He wai-ma.He mātotoru ake i te wai.Ira hiko 200°F.He paitini pea ma te horomia.Ka whakamahia i roto i nga wai whakamau. |
Tauhohenga Hau me te Wai | Wairewa ki te wai. |
Kōtaha Tauhohenga | Ko te 1,2-Diformyloxyethane ka tauhohe ki waho ki te waikawa.Me nga waikawa oxidizing kaha;ka mura pea te wera i nga hua tauhohenga.He tauhohenga hoki ki waho me nga otinga taketake.Ka whakaputa i te hauwai me nga matū whakaheke kaha (metara kawa, hydride). |
Pūmate | He paitini ma te horomia. |
Pūmate Hauora | Ko te whakamahu, te pa atu ranei ki nga taonga ka whakapataritari, ka wera ranei te kiri me nga kanohi.Ko te ahi ka puta mai he hau whakapouri, hauwai, paitini/ranei.Ko te kohu ka puta pea te mangere, te onge ranei.Ko te rere mai i te mana ahi, i te wai waimeha ranei ka puta te parahanga. |
Te mura me te pahū | Kore e mura |
Kōtaha Haumaru | Te paihana ma te horomia.He tino whakapouri kanohi.Ka tahuna ina pa ana ki te wera, ki te mura ranei;ka taea te tauhohe me nga mea whakahaora.Hei patu i te ahi, whakamahia te CO2, matū maroke.Ka wera ana ki te pirau ka puta te auahi kawa me nga kohu riri. |
