Triethanolamine (2-[Bis-(2-hydroxy-ethyl)-amino]-ethano)

Chilengedwe cha mankhwala

Triethanolamine ndi madzi opanda mtundu wa mafuta omwe ali ndi fungo la ammonia. Ndi yosavuta kuyamwa madzi ndipo imasintha mtundu wake kukhala bulauni ikakumana ndi mpweya ndi kuwala. Pa kutentha kochepa, imakhala yopanda mtundu kapena yachikasu yotuwa. Imasakanikirana ndi madzi, methanol ndi acetone. Imasungunuka mu benzene, ether, imasungunuka pang'ono mu carbon tetrachloride, n-heptane. Ndi mtundu wa alkaline wamphamvu, wophatikizidwa ndi ma proton, ndipo ungagwiritsidwe ntchito pochiza condensation.

Mapulogalamu

Mu chemistry yowunikira, triethanolamine ingagwiritsidwe ntchito ngati gawo lokhazikika la chromatography yamadzimadzi a gasi (kutentha kwakukulu ndi 75 ℃ pomwe chosungunuliracho ndi methanol ndi ethanol), chomwe chimagwiritsidwa ntchito polekanitsa pyridine ndi methyl substitutes. Mu complexometric titration ndi kusanthula kwina, ingagwiritsidwe ntchito ngati masking agent ya ma ions osokoneza. Mwachitsanzo, mu yankho la pH = 10, tikamagwiritsa ntchito EDTA pa titration ya magnesium, zinc, cadmium, calcium, nickel ndi ma ions ena, reagent ingagwiritsidwe ntchito pobisa titanium, aluminiyamu, chitsulo, tin ndi ma ions ena. Kuphatikiza apo, ingathenso kutchedwa hydrochloric acid kukhala buffer solution ya pH inayake.

Triethanolamine imagwiritsidwa ntchito kwambiri popanga zinthu zosungunulira madzi, zotsukira madzi, zodzoladzola ndi zina zotero. Ndi chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito podula madzi ndi madzi oletsa kuzizira. Panthawi yopopera mphira wa nitrile, ingagwiritsidwe ntchito ngati choyambitsa, kukhala choyambitsa vulcanization cha mphira wachilengedwe ndi mphira wopangidwa. Ingagwiritsidwenso ntchito ngati zosakaniza za mafuta, sera ndi mankhwala ophera tizilombo, chonyowetsa ndi chokhazikika cha zodzoladzola, zofewetsa nsalu komanso zowonjezera zotsutsana ndi dzimbiri za mafuta. Triethanolamine imathanso kuyamwa carbon dioxide ndi hydrogen sulfide ndi mpweya wina. Poyeretsa mpweya wa coke oven ndi mpweya wina wa mafakitale, ingagwiritsidwe ntchito pochotsa mpweya wa asidi. Ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri poyesa EDTA titration.

madzi achikasu opepuka/opanda mtundu

Nthawi yosungira zinthu

Malinga ndi zomwe takumana nazo, mankhwalawa akhoza kusungidwa kwa masiku 12.miyezi kuyambira tsiku loperekedwa ngati zasungidwa m'zidebe zotsekedwa bwino, zotetezedwa ku kuwala ndi kutentha ndikusungidwa kutentha pakati pa 5 -30°C.
