I-Diethylenetriamine CAS: 111-40-0

indalo
Ulwelo lwehygroscopic transparent transparent viscous kunye nevumba elimnandi leammonia, elinokutsha kunye nealkaline ngamandla. Inyibilika emanzini, i-acetone, ibenzene, i-ether, i-methanol, njl. Indawo yokunyibilika -35℃. Indawo yokubilisa 207℃. Ukuxinana okuzalanayo o. 9586. Indawo edanyazayo 94℃. Isalathiso se-refractive 1. 4810. Le mveliso ine-reactivity ye-amines yesibini kwaye isabela ngokulula ngeendlela ezahlukeneyo. I-derivatives yayo inoluhlu olubanzi lokusetyenziswa.

Indlela yokulungiselela
Inokufumaneka nge-ammoniation ye-dichloroethane. I-1,2-Ethyl chloride kunye namanzi e-ammonia athunyelwa kwi-reactor tubular ukwenza i-ammoniation reaction reaction eshushu kwiqondo lokushisa kwe-150-250 ° C kunye noxinzelelo lwe-392.3kPa. Isisombululo sokusabela singathathi hlangothi kunye ne-alkali ukufumana i-amines exutywe simahla, egxininiswe ngelixa isusa i-sodium chloride. Imveliso ekrwada ke ihlanjululwe phantsi koxinzelelo oluncitshisiweyo kwaye iqhezu eliphakathi kwe-195 kunye ne-215 ° C liyabanjwa ukufumana imveliso egqityiweyo. Le ndlela ivelisa i-ethylenediamine, i-triethylenetetramine, i-tetraethylenepentamine kunye ne-polyethylenepolyamine ngexesha elifanayo. Inokufumaneka ngokulawula ubushushu bombhobho we-distillation ukuze udibanise umxube we-amine kunye nokuqhawula amaqhezu ahlukeneyo ngokuhlukana.

sebenzisa
Le mveliso isetyenziswa kakhulu njenge-solvent kunye ne-organic synthesis intermediate, kwaye ingasetyenziselwa ukulungisa i-epoxy resin curing agents, izicoci zegesi (zokususa i-CO2), izongezo zeoli zokuthambisa, ii-emulsifiers, iikhemikhali zefoto, i-surfactants, kunye ne-ejenti zokugqiba ilaphu. , isiphuculi sephepha, i-aminocarboxylic complexing agent, i-metal chelating agent, i-heavy metal hydrometallurgy kunye ne-cyanide-free electroplating diffusion agent, i-brightener, kunye ne-synthetic ion exchange resin kunye ne-polyamide resin, njl.
