Ntchito ndi ntchito za diethanolamine

Diethanolamine (DEA) ndi organic pawiri ndi mankhwala chilinganizo C4H11NO2. Ndi madzi owoneka bwino opanda mtundu kapena kristalo omwe ali amchere ndipo amatha kuyamwa mpweya monga carbon dioxide ndi hydrogen sulfide mumpweya. Diethanolamine yoyera ndi yolimba yoyera kutentha kwa chipinda, koma chizolowezi chake cha deliquesce ndi supercool chimapangitsa nthawi zina kuwoneka ngati madzi opanda mtundu komanso owonekera. Diethanolamine, monga amine yachiwiri ndi diol, imakhala ndi ntchito zambiri popanga organic synthesis. Mofanana ndi mankhwala ena a amine, diethanolamine ndi yofooka kwambiri. Mu 2017, World Health Organisation's International Agency for Research on Cancer idatulutsa mndandanda wazomwe zimayambitsa khansa, ndikuphatikiza diethanolamine pamndandanda wamagulu a 2B carcinogens. Mu 2013, gululi lidadziwikanso kuti "mwina carcinogenic kwa anthu" ndi International Agency for Research on Cancer.

Ntchito ndi ntchito za diethanolamine

1. Amagwiritsidwa ntchito makamaka ngati mpweya wa asidi woyamwa, wosagwiritsa ntchito ionic, emulsifier, wopukuta, woyeretsa gasi wa mafakitale ndi mafuta monga CO2, H2S ndi SO2. Iminodiethanol, yomwe imadziwikanso kuti diethanolamine, ndi yapakatikati mwa herbicide glyphosate. Amagwiritsidwa ntchito ngati oyeretsa gasi komanso ngati zinthu zopangira mankhwala opangira komanso organic synthesis.

2. Diethanolamine ndi yapakatikati mu kaphatikizidwe ka organic. Mwachitsanzo, atha kugwiritsidwa ntchito popanga zinthu zina zowulitsa magetsi m'makampani opanga nsalu. Mafuta amchere amchere a morpholine angagwiritsidwe ntchito ngati zosungira. Morpholine angagwiritsidwenso ntchito kupanga chapakati mantha dongosolo depressant mankhwala pholcodine. kapena monga zosungunulira. Diethanolamine amagwiritsidwa ntchito mu chemistry yowunikira ngati reagent ndi gas chromatography stationary solution kuti asunge ndikulekanitsa mowa, glycols, amines, pyridines, quinolines, piperazines, thiols, thioethers, ndi madzi.

3. Diethanolamine ndi chinthu chofunika kwambiri cha corrosion inhibitor ndipo chingagwiritsidwe ntchito ngati inhibitor corrosion inhibitor mu boiler water treatment, coolant injini yamagalimoto, kubowola ndi kudula mafuta, ndi mitundu ina ya mafuta opaka mafuta. Amagwiritsidwanso ntchito mu gasi ngati choyamwitsa poyeretsa mpweya wa asidi. Amagwiritsidwa ntchito ngati emulsifier muzodzoladzola zosiyanasiyana ndi mankhwala. M'makampani opanga nsalu, amatha kugwiritsidwa ntchito ngati mafuta, kunyowetsa, zofewa ndi zina zopangira organic.

4. Amagwiritsidwa ntchito ngati kuyamwa asidi, plasticizer, softener, emulsifier, etc. mu zomatira. Amagwiritsidwanso ntchito ngati kuyamwa kwa mpweya wa acidic (monga hydrogen sulfide, carbon dioxide, etc.) mu mafuta a petroleum, gasi ndi mpweya wina. Ndi zopangira kwa synthesis wa mankhwala, mankhwala, utoto intermediates ndi surfactants. Amagwiritsidwa ntchito ngati emulsifier yamafuta ndi sera, komanso chofewa cha zikopa ndi ulusi wopangira pansi pa acidic. Amagwiritsidwa ntchito ngati thickener ndi thovu zowonjezera mu shampoos ndi zotsukira kuwala. Amagwiritsidwanso ntchito ngati zotsukira, zothira mafuta, zowunikira komanso zochotsa fumbi la injini ya piston.

5. Amagwiritsidwa ntchito ngati completing agent for silver plating, cadmium plating, lead plating, zinc plating, etc.

6. Amagwiritsidwa ntchito ngati ma analytical reagents, zotengera mpweya wa asidi, zofewa ndi mafuta, komanso mu kaphatikizidwe ka organic.
