Tetraethylenepentamine CAS No. 112-57-2
Sharaxaada Alaabta
Diethanolamine, oo inta badan loo soo gaabiyo DEA ama DEOA, waa iskudhis organic ah oo leh caanaha HN (CH2CH2OH) 2. Diethanolamine saafi ah waa adage cad oo heerkulka qolka ah, laakiin u janjeera inuu nuugo biyaha iyo inuu aad u qaboojiyo taasoo la micno ah inuu inta badan la kulmo dareere aan midab lahayn, viscous ah. Diethanolamine waa polyfunctional, isagoo ah amin sare iyo diol. Sida aminyada kale ee organic, diethanolamine waxay u shaqeysaa sidii saldhig daciif ah. Ka tarjumaysa dabeecadda hydrophilic ee amine sare iyo kooxaha hydroxyl, DEA waxay ku milmi kartaa biyaha. Amides-ka laga diyaariyey DEA inta badan sidoo kale waa hydrophilic. Sannadkii 2013 kii, kiimikadda waxa ay Hay’adda Caalamiga ah ee Cilmi-baadhista Kansarka u kala saartay “Suurtagalnimada Kansarka Bini’aadamka”.

Codsiga
| Inta badan waxaa loo isticmaalaa in synthesis of xabagta polyamide, xabagta sarrifka cation, saliid lagu daro saliidda, lagu daro saliidda shidaalka, iwm, sidoo kale waxaa loo isticmaali karaa sida epoxy resin daawo, dardar vulcanization caag. |
Diethanolamine waxaa loo isticmaalaa dareeraha shaqada birta si loo gooyo, shaabadeeyo iyo hawlgallada shubista dhimista sida daxal-horiyaha. Soo saarista saabuunta, nadiifiyeyaasha, dareerayaasha dharka iyo birta, diethanolamine waxaa loo isticmaalaa dhexdhexaadinta aashitada iyo dhigista ciidda. DEA waa cudur maqaarka ka cadhaysiin kara shaqaalaha lagu baraarugay soo-gaadhista dareerayaasha birta ku salaysan ee biyaha. Hal daraasad ayaa muujisay in DEA ay joojiso jiirarka dhallaanka nuugista choline, taas oo lagama maarmaan u ah horumarinta maskaxda iyo dayactirka;[8] si kastaba ha ahaatee, daraasad lagu sameeyay bini'aadamka ayaa go'aamisay in daaweynta maqaarka ee 1 bisha oo leh kareemka maqaarka oo ganacsi ahaan loo heli karo oo ay ku jiraan DEA waxay keentay DEA. Heerarka "oo aad uga hooseeya kuwa la xidhiidha korriinka maskaxda ee qallafsan ee jiirka" isbeddellada kiliinikada iyo histopathological, oo tilmaamaya dhiigga khafiifka ah, beerka, kelyaha iyo sunta habdhiska xiniinyaha.
DEA waa maqaar suurtagal ah oo xanaajin leh oo ku jira shaqaalaha oo dareensan soo-gaadhista dareeraha birta-ku-salaysan ee biyaha.Hal daraasad ayaa muujisay in DEA ay joojiso jiirarka ilmaha nuugista choline, taas oo lagama maarmaan u ah horumarinta maskaxda iyo dayactirka;[8] si kastaba ha ahaatee, daraasadda bini'aadamka waxaa la go'aamiyay in daawaynta maqaarka ee 1 bil oo la isticmaalay kareemka maqaarka ganacsi ahaan loo heli karo oo ay ku jirto DEA ay keentay in heerarka DEA ay "aad uga hooseeyaan kuwan la xidhiidha korriinka maskaxda ee qallafsan ee jiirka". Daraasad jiirka ah oo ku saabsan soo-gaadhista joogtada ah ee DEA la neefsado oo aad u sarreeya (ka sarreeya 150 mg / m3), DEA waxaa lagu ogaadey in ay keento isbeddelada miisaanka jidhka iyo xubnaha, isbeddelada bukaan-socodka iyo is-beddelka histopathological, oo tilmaamaya dhiigga khafiifka ah, beerka, kelyaha iyo sunta nidaamka xiniinyaha. Daraasad la sameeyay 2009 ayaa lagu ogaaday in DEA ay leedahay sifooyin ba'an, dabadheeraad ah iyo sifooyin hoosaadyo sun ah oo loogu talagalay noocyada biyaha.
Faa'iidada
Tayada badeecada, tiro ku filan, gaarsiinta wax ku oolka ah, tayada sare ee adeega Waxay leedahay faa'iido ka badan amine la mid ah, ethanolamine, in diirada sare loo isticmaali karo isla awooda daxalka. Tani waxay u ogolaanaysaa sifeeyayaasha inay xoqaan hydrogen sulfide oo ah heerka amiinada wareega hoose ee isticmaalka tamarta guud.
