Ntchito ndi Ntchito za Diethanolamine

Diethanolamine (DEA) ndi mankhwala achilengedwe okhala ndi formula ya mankhwala C4H11NO2. Ndi madzi kapena kristalo wopanda mtundu wopanda alkaline ndipo amatha kuyamwa mpweya monga carbon dioxide ndi hydrogen sulfide mumlengalenga. Diethanolamine yoyera ndi yoyera kwambiri kutentha kwa chipinda, koma chizolowezi chake chosintha kukhala madzi osalala komanso osalala nthawi zina chimapangitsa kuti nthawi zina chiwoneke ngati madzi opanda mtundu komanso owonekera. Diethanolamine, monga amine yachiwiri ndi diol, imagwiritsidwa ntchito kwambiri popanga zinthu zachilengedwe. Monga mankhwala ena a amine, diethanolamine ndi yosavuta kwenikweni. Mu 2017, bungwe la World Health Organization's International Agency for Research on Cancer linatulutsa mndandanda woyamba wa zinthu zomwe zimayambitsa khansa, ndipo linaphatikiza diethanolamine pamndandanda wa zinthu zomwe zimayambitsa khansa za Gulu 2B. Mu 2013, mankhwalawo adatchulidwanso kuti "akhoza kukhala khansa kwa anthu" ndi bungwe la International Agency for Research on Cancer.

Ntchito ndi Ntchito za Diethanolamine

1. Amagwiritsidwa ntchito makamaka ngati choyamwitsa mpweya wa asidi, chopanda ionic surfactant, choyeretsera, choyeretsera mpweya wa mafakitale komanso chopaka mafuta monga CO2, H2S ndi SO2. Iminodiethanol, yomwe imadziwikanso kuti diethanolamine, ndi gawo la glyphosate ya herbicide. Imagwiritsidwa ntchito ngati choyeretsera mpweya komanso ngati zinthu zopangira mankhwala opangidwa ndi mankhwala ndi organic synthesis.

2. Diethanolamine ndi gawo lapakati pa kapangidwe ka zinthu zachilengedwe. Mwachitsanzo, ingagwiritsidwe ntchito kupanga zinthu zina zoyeretsera kuwala mumakampani opanga nsalu. Mafuta acid a mchere wa morpholine angagwiritsidwe ntchito ngati zosungira. Morpholine ingagwiritsidwenso ntchito kupanga mankhwala ochepetsa nkhawa a dongosolo la mitsempha yapakati pholcodine. kapena ngati chosungunulira. Diethanolamine imagwiritsidwa ntchito mu chemistry yowunikira ngati reagent ndi gas chromatography stationary solution kuti isunge ndikulekanitsa mosankha ma alcohols, glycols, amines, pyridines, quinolines, piperazines, thiols, thioethers, ndi madzi.

3. Diethanolamine ndi chinthu chofunikira choletsa dzimbiri ndipo chingagwiritsidwe ntchito ngati choletsa dzimbiri poyeretsa madzi a boiler, choziziritsira injini zamagalimoto, mafuta obowola ndi odulira, ndi mitundu ina ya mafuta odzola. Chimagwiritsidwanso ntchito mu gasi wachilengedwe ngati choyamwitsa mpweya wa asidi woyeretsedwa. Chimagwiritsidwanso ntchito ngati emulsifier mu zodzoladzola zosiyanasiyana ndi mankhwala. Mu makampani opanga nsalu, chingagwiritsidwe ntchito ngati mafuta odzola, chonyowetsa, chofewetsa ndi zinthu zina zopangidwa ndi organic.

4. Amagwiritsidwa ntchito ngati choyamwitsa asidi, chopangira pulasitiki, chofewetsa, chosakaniza, ndi zina zotero mu zomatira. Amagwiritsidwanso ntchito ngati choyamwitsa mpweya wa asidi (monga hydrogen sulfide, carbon dioxide, ndi zina zotero) mu mpweya wa petroleum, gasi wachilengedwe ndi mpweya wina. Ndi chinthu chopangira mankhwala, mankhwala ophera tizilombo, zinthu zopaka utoto ndi zinthu zosungunulira. Amagwiritsidwa ntchito ngati chosakaniza cha mafuta ndi sera, komanso chofewetsa chikopa ndi ulusi wopangidwa pansi pa asidi. Amagwiritsidwa ntchito ngati chokhuthala ndi chowonjezera thovu mu shampu ndi sopo wopepuka. Amagwiritsidwanso ntchito ngati sopo, mafuta, chowunikira komanso chochotsa fumbi la piston ya injini.

5. Amagwiritsidwa ntchito ngati chothandizira chopangira siliva, cadmium plating, lead plating, zinc plating, ndi zina zotero.

6. Amagwiritsidwa ntchito ngati zinthu zowunikira, zoyamwitsa mpweya wa asidi, zofewetsa ndi zodzola, komanso ngati zinthu zopangidwa ndi organic.
