Diethylenetriamine CAS:111-40-0

chilengedwe
Madzi achikasu owoneka bwino, owoneka bwino, okhala ndi fungo la ammonia, oyaka komanso amphamvu. Amasungunuka m'madzi, acetone, benzene, ether, methanol, ndi zina zotero, osasungunuka mu n-heptane, ndipo amawononga mkuwa ndi zitsulo zake. Malo osungunuka -35℃. Malo otentha 207℃. Kuchulukana kwa Relative o. 9586. Malo owunikira 94℃. Chizindikiro cha Refractive 1. 4810. Chogulitsachi chili ndi reactivity ya ma amine achiwiri ndipo chimatha kuyanjana mosavuta ndi mankhwala osiyanasiyana. Zotumphukira zake zimagwiritsidwa ntchito mosiyanasiyana.

Njira yokonzekera
Ikhoza kupezeka mwa kusakaniza dichloroethane ndi ammonia. 1,2-Ethyl chloride ndi madzi a ammonia zimatumizidwa mu tubular reactor kuti zichite hot-pressure ammoniation reaction pa kutentha kwa 150-250°C ndi kuthamanga kwa 392.3kPa. Yankho la reaction limasinthidwa ndi alkali kuti lipeze ma mixed free amines, omwe amasungunuka pamene akuchotsa sodium chloride. Kenako chinthu chosaphikidwa chimasungunuka pansi pa kuthamanga kochepa ndipo gawo la pakati pa 195 ndi 215°C limachotsedwa kuti lipeze chinthu chomalizidwa. Njirayi imapanga ethylenediamine, triethylenetetramine, tetraethylenepentamine ndi polyethylenepolyamine nthawi imodzi. Ikhoza kupezeka powongolera kutentha kwa nsanja yosungunulira kuti isungunule amine osakaniza ndikuchotsa magawo osiyanasiyana kuti alekanitsidwe.

gwiritsani ntchito
Chogulitsachi chimagwiritsidwa ntchito makamaka ngati chosungunulira ndi chopangira zinthu zachilengedwe, ndipo chingagwiritsidwe ntchito pokonzekera zinthu zoyeretsera utomoni wa epoxy, zotsukira mpweya (zochotsera CO2), zowonjezera mafuta odzola, zosakaniza, mankhwala ojambula zithunzi, zinthu zosungunulira, ndi zinthu zomalizitsa nsalu. , chowonjezera mapepala, chothandizira aminocarboxylic complexing, chothandizira chelating chachitsulo, chothandizira kufalitsa zinthu za heavy metallurgy ndi cyanide-free electroplating, chowunikira, ndi chosinthira ma ion ndi polyamide resin, ndi zina zotero.
