Qxamine 12D, Dodecyl Amine, CAS 124-22-1
Dodecanaminetshwm raws li cov kua daj nrog ib qhoammonia-zoo li tsw.Insoluble hauvdejthiab tsawg duadej.Li no ntab raudej.Kev sib cuag tuaj yeem ua rau tawv nqaij, qhov muag thiab cov mucous membranes.Tej zaum yuav muaj tshuaj lom los ntawm kev noj, nqus pa lossis nqus ntawm daim tawv nqaij.Siv los ua lwm yam tshuaj.
Dawb waxy khoom.Soluble hauv ethanol, benzene, chloroform, thiab carbon tetrachloride, tab sis insoluble hauv dej.Tus txheeb ze ntom ntom 0.8015.Melting point: 28.20 ℃.Kub taw tes 259 ℃.Lub refractive index yog 1.4421.
Siv lauric acid ua raw khoom thiab nyob rau hauv lub xub ntiag ntawm ib tug silica gel catalyst, ammonia gas yog qhia rau amination.Cov tshuaj tiv thaiv cov khoom yog ntxuav, qhuav, thiab distilled nyob rau hauv lub siab txo kom tau refined lauryl nitrile.Hloov lauryl nitrile mus rau hauv lub nkoj uas muaj siab, do thiab kub rau 80 ℃ nyob rau hauv lub xub ntiag ntawm ib tug nquag nickel catalyst, pheej hydrogenation thiab txo kom tau crude laurylamine, ces txias nws, undergo lub tshuab nqus tsev distillation, thiab qhuav nws kom tau txais lub crude laurylamine. cov khoom tiav.
Cov khoom no yog cov organic hluavtaws intermediate siv nyob rau hauv zus tau tej cov textile thiab roj hmab additives.Nws kuj tseem siv tau los tsim cov tshuaj ore flotation, dodecyl quaternary ammonium ntsev, fungicides, tshuaj tua kab, emulsifiers, detergents, thiab tshuaj tua kab mob rau kev tiv thaiv thiab kho cov tawv nqaij kub hnyiab, nourishing thiab antibacterial agents.
Drips thiab xau, cov neeg ua haujlwm yuav tsum hnav cov khoom tiv thaiv.
Raws li kev hloov kho hauv kev npaj ntawm dodecylamine suav nrog sodium montmorillonite.Nws yog siv los ua ib qho adsorbent rau hexavalent chromium.
● Nyob rau hauv cov synthesis ntawm DDA-poly (aspartic acid) raws li biodegradable dej-soluble polymeric khoom.
● Raws li cov organic surfactant nyob rau hauv cov synthesis ntawm Sn (IV)-muaj txheej txheej ob hydroxide (LDHs), uas yuav siv tau ntxiv raws li ion exchangers, absorbents, ion conductors, thiab catalysts.
● Ua ib tug complexing, txo thiab capping tus neeg sawv cev nyob rau hauv lub synthesis ntawm pentagonal nyiaj nanowires.
