Diethyl monoisopropanolamine
Kupu Whakataki
Diethyl waipiro monoisopropanolamine Ko te momo o te mea waro, tātai matū C7H17O3N, kowhai marama marama marama marama ki te hā haukini whakaihiihi wai viscous, pūmau i te pāmahana rūma me te pēhanga.Ko te monoisopropanolamine waipiro o Diethyl he momo hou o te rauemi awhina huri kakariki, e kitea ana te kaha o te awhina hurihuri, a ka whakamahia nuitia i roto i te awhina huri sima.
(1) Diethanolamine monoisopropyl olamine te nuinga whakamahia i roto i surfactants, whakamahia whānuitia i roto i te matū raw rauemi, pigments, rongoa, rauemi hanga me etahi atu mara, i roto i tāpiritanga sima, hua tiaki kiri me te kakano softener atu tono.
(2) I tenei wa, i roto i te waahi o te ciment hurihanga AIDS, ko te nuinga o nga hanganga he hua kotahi, he huinga ranei o te waipiro, te amine waipiro, te acetate me etahi atu rauemi mata matū.Ka whakatauritea ki etahi atu taapiri ciment rite, he nui nga painga o te diethyl alcohol monoisopropyl alcohol amine (DEIPA) ki te whakapai i te mahi huri, te penapena hiko me te whakaheke kai me te whakapai ake i te kaha sima.
Tikanga Whakaputa
1.Ko te whakahiato o te monoisopropanolamine (DEIPA) e toru nga huarahi matua: tuatahi, ko te whakahiato tauhohenga o te haukini me te ethylene oxide (EO) me te propylene oxide (PO);
Tuarua, he mea hanga na te tauhohenga o te MIPA me te EO.Tuatoru, he mea whakahiato mai i te diethanolamine (DEA) me te PO.
2.Amoni me te ara tauhohenga epoxy olefin
Ko tenei ara he tauhohenga raupapa e toru nga waahanga.Ka tauhohe te haukini me te EO hei whakaputa i te ethanolamine, diethanolamine me te triethanolamine.Ka whakahiatohia nga tauhohenga ki te PO, a ka whiwhi nga hua whai muri i te purenga.Ranei, ka tauhohe te haukinia ki te PO ki te whakaputa i te monoisopropanolamine, te diisopropanolamine me te triisopropanolamine, ka whakahiatotia te reactant ki te EO, a ka whiwhi te hua whai i muri i te purenga.
3. ara DEA
Ka whakamahia e tenei ara te tauhohenga DEA me te PO ki te whakaputa i te matū DEIPA.Ko te painga o tenei huarahi he tere te tere o te tauhohenga, he nui te whiriwhiringa o te tauhohenga, he rawaka, he pumau hoki te tuku rauemi mata.Ko ta maatau mahi DEIPA, i tenei wa, ka whakamahi katoa i tenei huarahi, engari he rereke te rereketanga o te tipu whakaputa, te tauhohenga paipa ranei, i roto i te isomer hua me te pumau o te kounga.
