Ngā āhuatanga ā-tinana, ā-matū hoki o te MDEA te kaupapa whakakore waromō te hau māori
Ko te MDEA, ingoa pūtaiao ko N-methyldiethanolamine, he wai matotoru, kāore he tae, he paku kōwhai rānei.
Tātai ngota: CH3N(CH2CH2OH)2,
Te pāmahana koropupū: 246~249 ℃ /760mmhg; te taumaha motuhake: 1.0425g/ml (20 ℃);
Te pūwāhi tio: -21 ℃ (te parakore 99%); te matotoru: 101Cp (20 ℃);
Ka ngāwari te whakaranu ki te wai, te etanoru, te etera, me ētahi atu; he ngoikore te kawakore i roto i te wai; ka puta te tauhohenga matū i roto i te hauhā waro waikawa me te hau hauwai whanariki, ā, i te pēhanga teitei ake, ka nui ake te tauhohenga matū o te hauhā waro me te hau hauwai whanariki. Nō reira, ko te tukanga mimiti katoa he tukanga mimiti ā-tinana, ā-matū hoki.
I muri i te mimiti i te hauwai whanariki me te hauhā waro, ka tomo te wai MDEA ki te tāke mura hei mimiti tere i te korehau, kātahi ka tukuna ki te pourewa whakaora. Ka whakamahanahia te wai momona, ka pirau i te raro o te pourewa kia tukuna katoatia te hauhā waro me te hauwai whanariki. I taua wā anō, ka piki te hau i te raro o te pourewa hei hanga i tētahi pānga tangohanga tuarua ki te wai momona i te tihi o te pourewa; nō reira, ko te tukanga whakaora katoa he tukanga whakaora ā-tinana, ā-matū hoki. Ko te tauhohenga matū motuhake koia tēnei:
R2R'N + H2S R2R'NH +HS (tauhohenga inamata)
R2R'N+CO2+ H2O R2R'NH +HCO3 (tauhohenga puhoi)
Te mimiti me te whakaora anōte kaupapa whakakore waromō te hau māori
I muri i te urunga o te hau whāngai ki te rohe pākahiko, ka tangohia ngā paru me ngā pata o te hau e te wehewehe tātari, ā, ka tomo ki te pourewa mimiti mai i raro. I roto i te pourewa, ka whakapā atu te au ki te otinga MDEA i rehuhia mai i runga. Ka mimiti te otinga wai MDEA (te otinga amine kikokore) i te hauwai whanariki me te hauhā waro i roto i te hau māori, kia tangohia ai te hauwai whanariki me te hauhā waro i roto i te hau whāngai kia tutuki ai ngā whakaritenga hangarau a te rangatira. Ka tukuna te hau parakore ki waho o te rohe mā te wehewehe hau hua i muri i te wehenga atu i te tihi o te pourewa mimiti.
I raro i te mana o te takirere whakahaere taumata wai, ka haria e te taumata wai i raro i te pourewa mimiti te amine momona ki te tāke mura. Ka tomo te amine momona mai i raro i te pourewa mimiti ki te tāke mura. Ko te nuinga o ngā warowaihā e mimitihia ana ki te amine momona ka mimitihia ki te wāhanga hau mura. I raro i te mana o te takirere whakahaere pēhanga, ka whakahokia te mamaoa mura ki te pūnaha hau wahie. Ka tukuna te wai amine momona ki te whakawhiti wera amine kikokore/whai taonga. Ka whakamahanahia e te amine kikokore wera mai i te pourewa whakaora te amine momona mai i te tāke mura, kātahi ka tomo te amine momona ki te pourewa whakaora amine.
Ka pā te mamaoa e whakaputaina ana e te kohua hou i raro i te pourewa whakahou amine ki te wairewa amine whai rawa e rere ana i te au, ka tangohia te hau waikawa mai i roto, ā, ka oti te whakahou o te amine whai rawa. I raro i te mana o te takirere whakahaere taumata wai i raro i te pourewa whakahou amine, ka puea ake te wairewa amine kikokore wera ki te whakawhiti wera amine kikokore/whai rawa. Ka pēhia te amine i roto i te tāke ārai amine e te papu whakanui amine kikokore e te 1.0mpa, ka tukuna ki te pourewa mimiti. Ka tāutahia he takirere whakahaere rere ki runga i te paipa amine kikokore ki te pourewa mimiti, mā roto i tēnā ka whakahaeretia te rere o te amine kikokore ki roto i te pourewa mimiti.
