Diethylenetriamine CAS 111-40-0

Ndi madzi opanda mtundu kapena opepuka achikasu owoneka bwino okhala ndi fungo la ammonia ndi mkwiyo. Kutentha kwapang'onopang'ono ndi 0.9542 (20 ℃), malo osungunuka ndi -39 ℃, malo otentha ndi 207 ℃, ndi 94 ℃. Amasungunuka m'madzi, ethanol ndi acetone, osasungunuka mu ether. Ndi wamchere kwambiri ndipo umalimbana ndi asidi kupanga mchere wofanana. Pangani ma complexes mosavuta ndi salt metal heavy. Ndi hygroscopic kwambiri ndipo imatenga mosavuta chinyezi ndi carbon dioxide mumlengalenga, kupanga utsi woyera mumlengalenga. Zimawononga kwambiri ndipo zimawononga ma aloyi amkuwa ndi amkuwa. Zowononga kwambiri komanso zowononga khungu, mucous nembanemba ndi kupuma thirakiti.

[Gwiritsani ntchito]

Amagwiritsidwa ntchito ngati organic synthesis intermediates ndi solvents. Amagwiritsidwa ntchito popanga utomoni wa polyamide, ma ion exchange resins, ma surfactants, zowonjezera zamafuta, zomalizitsa nsalu ndi mankhwala ojambula zithunzi. Amagwiritsidwanso ntchito ngati chochizira kutentha kwachipinda cha epoxy resin, chotsuka gasi, chowonjezera mapepala, aminocarboxylic complexing agent, metal chelating agent, lightener, etc.

[Njira yokonzekera mwachidule] Imakonzedwa pochita kuyamwa kwa kutentha kwapakati ndi ammonolysis pakati pa dichloroethane ndi ammonia pa 100 ~ 150 ℃ ndi 4MPa, kusokoneza ndi alkali ndiyeno kusungunula. The reaction formula ndi motere:

[Chitetezo ndi Chitetezo]

Imadzaza mumigolo yapulasitiki ya polyethylene yokhala ndi ukonde wolemera 50kg pa mbiya; imathanso kulongedza migolo yachitsulo yokhala ndi ukonde wolemera 200kg pa mbiya; pang'onopang'ono, ikhoza kudzazidwa mu mabotolo agalasi a 0.5kg kapena 1kg. Sungani pamalo ozizira ndi mpweya wabwino, ndipo musakhale pamodzi ndi kunyamula ndi zidulo.

Izi ndi zamadzimadzi zowononga zamchere kwambiri. Ngati khungu likhudzidwa, litsuke nthawi yomweyo ndi madzi kapena kuchepetsa boric acid solution.
