Diisopropyl ether

Ngā āhuatanga matū:

He wai kore tae, he wai mura, he ngāwari te huri, he āhua rerekē te āhua, he kakara etera motuhake. Ka taea e ia te hanga i tētahi azeotrope me te wai, te waipiro isopropyl, te acetone, te acetonitrile me te etanoru.

Kaupapa:

He pai te whakarewa o te diisopropyl ether mō ngā hinu me ngā ngako kararehe, huawhenua me ngā kohuke. Ka taea te whakamahi hei tango i te nikotīni mai i te tupeka. He pai hoki te whakarewa mō te ware piro me te kapia. I roto i te ahumahi, he maha ngā wā ka konatunatua te diisopropyl ether ki ētahi atu whakarewa hei whakamahi ki ngā hua paraffin. Te tukanga tango hinu. Hei whakarewa, ka whakamahia hoki i roto i ngā rongoā, ngā matū kore paowa, ngā paninga me te horoi peita. He nui te tau octane o te diisopropyl ether me ngā āhuatanga ārai-huka, ā, ka taea te whakamahi hei kaiwhakaranu penehīni. Ka ngāwari te hanga peroxide o tēnei hua, ā, ka pahū ina rūrūtia. He maha ngā wā ka tāpirihia te para-benzylaminophenol hei whakau. He māmā ake te pānga whakangote o te diisopropyl ether i te diethyl ether, engari he roa ake te roa o te whakangote.

Tikanga Whakaputa I roto i te ahumahi, ka taea te tango mai i te hua taha o te waipiro isopropyl i hangaia mai i te whakamakuku o te waikawa whanariki propylene. Ka tauhohe te propylene ki te waikawa whanariki hei hanga i te isopropyl hydrosulfate, ka whakamakukuhia hei waipiro isopropyl. I roto i te tauhohenga, ka haere tonu te tauhohenga o te isopropyl hydrogen sulfate me te propylene hei hanga i te diisopropyl sulfate, ka tauhohe ki te waipiro isopropyl hei hanga i te isopropyl hydrogen sulfate me te diisopropyl ether. I muri i te tauhohenga whakamakuku waikawa whanariki, ka tangohia te rauemi Chemicalbook ki te mamaoa i roto i te pourewa mimiti hei tuku i te waipiro isopropyl me te diisopropyl ether mai i te otinga waikawa. Kātahi, mā te whakahoro, ka whiwhi tuatahitia te diisopropyl ether mai i te tihi o te pourewa. I roto i te taiwhanga, ka taea te whiwhi i te isopropyl ether mā te whakamaroke i te waipiro isopropyl ki te waikawa whanariki, mā te whakamakuku rānei i te waipiro isopropyl me te acetone. Ka taea hoki te hanga mā te whakapūngao catalytic o te waipiro isopropyl me te propylene. Ka taea hoki te whakaputa i te diisopropyl ether mā te tikanga kapia whakawhiti katote.
