Cov Khoom Siv Lub Cev
1.Cov tsos thiab xeev: Ntawm qhov kub thiab kub li qub thiab siab, nws yog ib qho xim tsis muaj kob lossis me ntsis daj ua kua nrog me ntsis ammonia tsw.
2.Hygroscopicity: Nws muaj cov khoom siv hygroscopic muaj peev xwm, muaj peev xwm ntawm kev nqus dej noo thiab cov pa roj carbon dioxide los ntawm huab cua.
3.Kub taw tes: kuj tseem ceeb, kwv yees li 170 degree. Qhov no yog vim muaj qhov kev sib tw hydrogen muaj zog ntawm cov lwg me me.
4.Melting taw tes: kwv yees li 10.5 degree, yog li nws yuav ua tau solalify rau ib puag ncig.
5.Ceev: Ntau dua li cov dej ntawd.
6.So: Nrog dej: infinitely me nyuam. Qhov no yog ib qho ntawm nws lub cev tseem ceeb tshaj plaws.With o organic cov kuab tshuaj, thiab ntau yam me ntsis solvents, benzene, thiab n - heptane.
7.Viscosity: Muaj qee yam viscosity thiab mloog 'oily'.
Tshuaj Tshuaj Muaj Zog
Cov amino pab pawg hauv Mea Molecule muab nws yooj yim, tso cai los ua kom hnov cov kua qaub los ua cov ntsev.
Nws cov kua aqueous yog alkaline ntau dua li cov dej ammonia, tab sis tsis muaj zog tshaj sodium hydroxide. Nws yog hom ntawm lub hauv paus tsis muaj zog.
Piv txwv piv txwv: Hoch₂ch₂nh₂ + HCL → Hoch₂chchChChCl⁻
Nov yog qhov kev lag luam tseem ceeb tshaj plaws hauv paus ntawm mea. It can undergo reversible reactions with acidic gases such as carbon dioxide (CO₂) and hydrogen sulfide (H₂S).
Reacts nrog CO₂: tsim ib qho tsis ruaj khov carbamate, ib qho tshuaj tiv thaiv uas tuaj yeem hloov kho siab rau thaum muaj kev sib zog ntawm cov cua sov, li ntawd} + h₂ + h₂ + h₂ - ⇌ (hoch₂ch₂nh₃) ₂co₃
Cov yeeb yaj kiab no ua rau nws cov kuab tshuaj uas nyiam hle kom tshem tau cov roj thiab roj av, siv hluav taws xob, thiab cov khoom siv hluav taws xob (feem ntau yog 'desulfurization').
Muaj peev xwm hnov mob nrog Epoxides xws li Ethylene oxide los tsim cov lwg me me ntawm ethanolamine derivatives.
Nws cov amino pab pawg tuaj yeem tshwm sim nrog cov kua qaub, acid anhydrides, acyl chlorides, thiab lwm yam, txhawm rau txhawm rau txhawm.
Tshwj xeeb tshaj yog nyob rau hauv cov chaw nyob nrog cov kev kub siab, thiab qib siab ntawm cov kev daws teeb meem yog cov kev daws teeb meem heev rau cov hlau ua hlau. Hauv kev siv cov ntawv thov, feem ntau nws yuav tsum tau ntxiv corrosion inhibitors lossis siv cov khoom siv hlau tsis muaj hlau.
Cov ntawv thov tseem ceeb (raws li nws cov yam ntxwv)
Roj Pa Roj Pa Roj:kev siv ntau tshaj plaws. Nws yog siv rau desulfurization ntawm cov pa roj av, daws cov hluavtaws ammonia pub roj, thiab ntes ntawm kev koom ua ke los ntawm Flue Roj, thiab lwm yam.
Surfactants: Siv los ua cov nruab nrab rau kev tsim cov emulsifiers, tshuaj ntxuav, textile auxilies, thiab lwm tus.
Kws muag tshuaj thiab tshuaj tua kab:Siv los ua cov nruab nrab rau kev sib xyaw ntau yam tshuaj (xws li cov sedatives thiab antihistamines) thiab tshuaj tua kab.
Maas sib tsoo kev pab:Raws li ib qho ntawm cov khoom siv raw, nws txhim kho kev sib tsoo ua tau zoo ntawm xis mas.
Cov tshuaj pleev ib ce:Siv los tsim cov roj av fatty acid saib xyuas cov khoom lag luam saib xyuas tus kheej, ua haujlwm raws li cov thickeners thiab ua npuas ncauj khov kho.
Hlau ua haujlwm:Ntxiv rau kev txiav cov kua thiab xeb -}}}} Kev tiv thaiv cov dej ua cov kws tiv thaiv corrosion.
Kev Nyab Xeeb thiab Cia (Cov Lus Tseem Ceeb)
TOXICICITY: Nws muaj qee theem ntawm kev lom zem thiab muaj khaus heev thiab corrosive rau lub qhov muag, tawv nqaij, thiab ua pa tawm. Kev nqus tau ntawm nws cov vapors lossis meryom tuaj yeem ua rau lub tshuab ua pa, thiab sib cuag nrog cov kua tuaj yeem ua rau lub qhov muag thiab tawv nqaij hnyav.
Flammability: nplaim taws nrog kua nrog muaj kwv yees li ntawm 93 degree, faib ua cov khoom siv sib xyaw ua ke.
Cia: Yuav tsum tau muab cia rau hauv cov thawv ntim, raws li nws yuav nqus pa thiab noo noo khoom yuav tsum nyiam dua cov hlau uas tsis muaj roj hlau, iav, lossis polyethylene yas. Zam txhob siv tooj liab, txhuas, thiab lawv cov aluminium, raws li MEA yuav tshwm sim nrog lawv.Tore hauv qhov chaw txias, muaj cua sov, thiab qhov chaw qhuav.
