I-Diethylenetriamine CAS:111-40-0

indalo
Ulwelo olutyheli olucacileyo noluthambileyo olunevumba elibi le-ammonia, olunokutsha kwaye olune-alkaline enamandla. Lunyibilika emanzini, i-acetone, i-benzene, i-ether, i-methanol, njl.njl., alunyibiliki kwi-n-heptane, kwaye luyabola kwi-copper kunye nee-alloys zayo. Iqondo lokunyibilika -35℃. Iqondo lokubila 207℃. Uxinano oluhambelanayo o. 9586. Iqondo lokutsha 94℃. Isalathisi sokurhawuzelela 1. 4810. Le mveliso inokusabela kwee-amines zesibini kwaye isabela ngokulula kwiindidi ezahlukeneyo zeekhompawundi. Iimveliso zayo zinoluhlu olubanzi lokusetyenziswa.

Indlela yokulungiselela
Ingafunyanwa ngokuxutywa kwe-dichloroethane. I-1,2-Ethyl chloride kunye namanzi e-ammonia zithunyelwa kwi-reactor yetyhubhu ukuze zenze i-ammoniation reaction yoxinzelelo olushushu kubushushu obuyi-150-250°C kunye noxinzelelo lwe-392.3kPa. Isisombululo se-reaction siyasuswa nge-alkali ukuze kufunyanwe ii-amines ezixutyiweyo, ezixutyiweyo ngelixa kususwa i-sodium chloride. Imveliso ekrwada emva koko iyanyibilikiswa phantsi koxinzelelo oluncitshisiweyo kwaye iqhezu eliphakathi kwe-195 kunye ne-215°C liyathintelwa ukuze kufunyanwe imveliso egqityiweyo. Le ndlela ivelisa i-ethylenediamine, i-triethylenetetramine, i-tetraethylenepentamine kunye ne-polyethylenepolyamine ngaxeshanye. Ingafunyanwa ngokulawula ubushushu be-distillation tower ukuze kuxutywe umxube we-amine kunye nokuthintela iiqhezu ezahlukeneyo ukuze zahlulwe.

sebenzisa
Le mveliso isetyenziswa kakhulu njenge-solvent kunye ne-organic synthesis intermediate, kwaye ingasetyenziselwa ukulungiselela ii-epoxy resin curing agents, ii-gas purifiers (zokususa i-CO2), izongezo zeoyile zokuthambisa, ii-emulsifiers, iikhemikhali zefoto, ii-surfactants, kunye nee-factants zokugqiba ilaphu. , i-paper enhancer, 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.
