Diethylenetriamine CAS 111-40-0

Ndi madzi amafuta opanda mtundu kapena achikasu owala, owonekera bwino okhala ndi fungo la ammonia komanso kuyabwa. Kuchuluka kwa kuyaka ndi 0.9542 (20℃), kutentha ndi -39℃, kutentha ndi 207℃, ndipo kutentha ndi 94℃. Amasungunuka m'madzi, ethanol ndi acetone, osasungunuka mu ether. Ndi amchere kwambiri ndipo amakumana ndi asidi kupanga mchere wofanana. Amapangidwa mosavuta ndi mchere wachitsulo cholemera. Ndi hygroscopic kwambiri ndipo amayamwa mosavuta chinyezi ndi carbon dioxide mumlengalenga, ndikupanga utsi woyera mumlengalenga. Amawononga kwambiri ndipo amawononga zinthu zamkuwa ndi zamkuwa. Amawononga kwambiri ndipo amakwiyitsa khungu, nembanemba ya mucous ndi njira yopumira.

[Gwiritsani ntchito]

Amagwiritsidwa ntchito ngati zinthu zosakaniza zachilengedwe komanso zosungunulira. Amagwiritsidwa ntchito popanga ma polyamide resins, ma ion exchange resins, ma surfactants, zowonjezera mafuta, zomaliza nsalu ndi mankhwala ojambula zithunzi. Amagwiritsidwanso ntchito ngati chothandizira kutentha kwa chipinda cha epoxy resin, chotsukira gasi, chothandizira kulimbitsa mapepala, chothandizira aminocarboxylic complexing, chothandizira chelating chachitsulo, chowunikira, ndi zina zotero.

[Njira yokonzekera mwachidule] Imakonzedwa pochita zinthu monga hot-pressure amination ndi ammonolysis reactions pakati pa dichloroethane ndi ammonia pa 100~150℃ ndi 4MPa, kuichepetsa ndi alkali kenako n’kuisungunula. Njira yochitira izi ndi iyi:

[Chitetezo ndi Chitetezo]

Imayikidwa m'migolo yapulasitiki ya polyethylene yokhala ndi kulemera kokwana 50kg pa mbiya; imathanso kuyikidwa m'migolo yachitsulo yokhala ndi kulemera kokwana 200kg pa mbiya; pang'ono, imatha kuyikidwa m'mabotolo agalasi a 0.5kg kapena 1kg. Sungani pamalo ozizira komanso opumira mpweya, ndipo musakhale pamodzi ndipo musanyamule ndi asidi.

Mankhwalawa ndi madzi owononga kwambiri okhala ndi alkaline. Ngati khungu likakhudza, litsukeni nthawi yomweyo ndi madzi kapena chepetsani boric acid.
