Diethylenetriamine CAS:111-40-0

taiao
Kowhai kowhai hygroscopic wai kikorangi marama me te haukinia kakara, he mura me te kaha kawakore. Wairewa ki te wai, acetone, benzene, ether, methanol, me etahi atu, kare e rewa i roto i te n-heptane, ka pirau ki te parahi me ona koranu. Ira whakarewa -35℃. Ira kohua 207℃. Kiato whanaunga o. 9586. Ira hiko 94℃. Taupū Refactive 1. 4810. Ko tenei hua te tauhohenga o nga amine tuarua, a he ngawari te tauhohenga ki nga momo puhui. He maha nga whakamahinga o ona hua.

Tikanga whakarite
Ka taea te whiwhi ma te ammoniation o te dichloroethane. Ka tukuna te 1,2-Ethyl chloride me te wai haukini ki roto i te reactor tubular ki te mahi i te tauhohenga haukini wera-wera i te mahana o te 150-250°C me te pehanga 392.3kPa. Ka whakakorehia te otinga tauhohenga ki te kawakore kia whiwhi ai i nga amine kore utu, ka kukū i te tango i te konutai pūhaumāota. Ka whakamarokehia te hua masivesivá i raro i te pehanga iti, ka haukotia te hautanga i waenga i te 195 me te 215°C kia whiwhi ai i te hua kua oti. Ko tenei tikanga ka whakaputa tahi i te ethylenediamine, triethylenetetramine, tetraethylenepentamine me te polyethylenepolyamine i te wa ano. Ka taea te whiwhi ma te whakahaere i te pāmahana o te pourewa whakamarumaru ki te whakamarumaru i te ranunga amine me te haukoti i nga hautau rereke mo te wehenga.

whakamahi
Ko te nuinga o tenei hua ka whakamahia hei takawaenga whakarewa me te whakahiato pararopi, ka taea te whakamahi ki te whakarite i nga rongoa rongoa epoxy resin, nga purifiers hau (mo te tango CO2), nga taapiri hinu whakahinuhinu, emulsifiers, matū whakaahua, surfactants, me nga taputapu whakaoti papanga. , whakaniko pepa, aminocarboxylic complexing agent, whakarewa chelating agent, heavy metal hydrometallurgy and cyanide-free electroplating diffusion agent, brightener, and synthetic synthetic exchange resin and polyamide resin, etc.
