3-Dimethylaminopropylamine CAS: 109-55-7
He momo matū nui te diamine e whakamahia whānuitia ana hei rauemi mata, hei takawaenga, hei hua rānei. Hei tauira, he wāhanga hanganga nui te diamine i roto i te hanganga o te polyamide me ētahi atu tauhohenga polymerization condensation. He takawaenga nui te N,N-dimethyl-1Chemicalbook,3-diaminopropane (DMAPA), e whakamahia ana hei tauira i roto i te whakaritenga ahumahi o ngā hinu whakahinuhinu. Hei tāpiri, ka whakamahia te DMAPA hei rauemi mata mō te whakarite i ngā coagulants, ā, me whai āhuatanga ārai-waikura anō hoki.
He wai mārama, kāore he tae. Ka wairewa ki te wai me ngā whakarewa waro. He whānuitia te whakamahinga i roto i te hanga rauemi mata whakapaipai, pērā i te palmitamide dimethylpropylamine, te cocamidopropyl betaine, te hinu mink amidopropylamine, me ētahi atu.
Mā te whakamahi i te dimethylaminopropionitrile [1738-25-6] hei rauemi mata, ka tāpirihia te hauwai me te methanol i te aroaro o te whakakorikori Ni-Al, kātahi ka tātarihia, ka whakahoroa kia puta ai te hua oti o te 3-dimethylaminopropylamine. Ka taea e te parakore o te hua i whiwhi te eke ki te neke atu i te 99%, ā, ka pau i ia tana o te hua te 1150kg o te dimethylaminopropionitrile. -

N,N-Dimethylformamide CAS 68-12-2
He wai mārama, kore tae te Dimethylformamide. Ehara i te mea he rauemi matū whānuitia anake, engari he whakarewa pai hoki me te whānuitanga o ngā whakamahinga. He rauemi mata nui te Dimethylformamide mō ngā ahumahi rongoā, hinu matū, hiako me ētahi atu ahumahi.
Ko te Dimethylformamide e kiia nei ko te DMF. He matū tēnei e whakakapia ana te rōpū hydroxyl o te waikawa formic e te rōpū dimethylamino, ko te tātai ngota HCON(CH3)2. He wai kore tae, mārama hoki, he nui te kohua, he kakara amine māmā, ā, ko te mātotoru whanaunga he 0.9445 (25℃). Te pūwāhi rewa -61℃. Te pūwāhi koropupū 152.8℃. Te pūwāhi mura 57.78℃. Te mātotoru kohu 2.51. Te pēhanga kohu 0.49kpa (3.7mmHg25℃). Ko te pūwāhi mura aunoa he 445℃. Ko te rohe pahūtanga o te ranunga mamaoa me te hau he 2.2~15.2%. Mēnā ka pāngia e ngā mura tuwhera me te wera nui, ka mura pea, ka pahū. Ka taea e ia te tauhohe kaha ki te waikawa whanariki kukū me te waikawa hauota paowa, ā, ka pahū anō hoki. Ka taea te whakaranu ki te wai me te nuinga o ngā whakarewa waro. He whakarewa noa mō ngā tauhohenga matū. Kāore he kakara o te dimethylformamide parakore, engari he kakara ika te dimethylformamide kounga ahumahi, kua pirau rānei, nā te mea he paru dimethylamine kei roto. I ahu mai te ingoa i te mea he whakakapinga dimethyl o te formamide (amide o te waikawa formic), ā, kei runga i te ngota N (hauota) ngā rōpū methyl e rua. Ko te Dimethylformamide he whakarewa aprotic polar (hydrophilic) me te ira kohua teitei, ka taea te whakatairanga i te tikanga tauhohenga SN2. Ka hangaia te Dimethylformamide mai i te waikawa formic me te dimethylamine. Kāore te Dimethylformamide i te pumau (ina koa i ngā pāmahana teitei) i te aroaro o ngā turanga kaha pēnei i te konutai hauwai, ngā waikawa kaha pēnei i te waikawa hauwaiora, te waikawa whanariki rānei, ā, ka waikura hei waikawa formic me te dimethylamine.
He tino pumau i te hau, ā, ina werahia kia koropupū. Ina neke ake te pāmahana i te 350°C, ka ngaro te wai, ka puta he hauota waro me te dimethylamine. He tino pai te whakarewa porotaka aprotic te N,N-dimethylformamide e taea ai te whakarewa i te nuinga o ngā matū waro me ngā matū kore-waro, ā, ka taea te whakaranu ki te wai, ngā waipiro, ngā ether, ngā aldehyde, ngā ketone, ngā esters, ngā hauwaiwaro halogenated me ngā hauwaiwaro kakara. . Ko te pito pai o te ngota ngota N,N-dimethylformamide e karapotia ana e ngā rōpū methyl, e hanga ana i tētahi arai ā-wāhi e ārai ana i ngā katote kino mai i te whakatata mai, ā, ka hono noa i ngā katote pai. He nui ake te kaha o ngā anion tahanga i ngā anion kua whakarewahia. He māmā ake te mahi i ngā tauhohenga ionic maha i roto i te N,N-dimethylformamide i ngā whakarewa protic whānui. Hei tauira, ka tauhohe ngā carboxylates me ngā hauwaiwaro halogenated i roto i te N,N-dimethylformamide i te pāmahana rūma. , ka taea te whakaputa i ngā esters me ngā hua teitei, ā, he tino pai mō te hanga i ngā esters aukati-sterically.
