I-DEA (iDiethylamine)

Ngokwekhemikhali

Lulwelo olungenambala, olunokutsha olunevumba elibi le-ammonia. Luxutywa namanzi, i-ethanol, i-ether kunye nezinye izinyibilikisi zendalo.

Ukusetyenziswa:

I-Diethylamine sisinyibilikisi kunye nekhemikhali esiphakathi kwezinto ezikrwada. Ingasetyenziselwa ukulungiselela amayeza anjenge-procaine, i-chloroquine, i-nicosamid, i-colamin kunye ne-sulfonamides. Ingasetyenziselwa ukuvelisa izibulali-zinambuzane, iidayi, izikhawulezisi zerabha ze-vulcanization, njl. I-arhente yokucubungula izimbiwa (i-sulfur kunye ne-nitrogen No. 9), izincedisi zelaphu, ii-bactericides, izithinteli zokubola, izithinteli zokupholisha kunye nee-antifreeze agents, njl.

indlela yemveliso

Indlela ye-Ethanol yoxinzelelo lwegesi yesigaba se-atmospheric pressure gas catalysis ixuba i-gas phase ethanol, i-ammonia kunye ne-hydrogen kumlinganiselo we-1:0.8:1.5 (mol), ize ingene kwi-reactor yokuqala exhotyiswe nge-copper-nickel catalyst emva kokufudumeza kwangaphambili (170-180°C), kwi-195-200°C. I-gas-phase catalytic reaction yenziwa kwi-170-175°C, ize ingene kwi-reactor yesibini i-Chemicalbook ene-copper-nickel catalyst yokusabela kwe-synthesis, kwaye incitshiswa kwi-170-175°C ukususa ukungcola okufana ne-acetonitrile. I-reaction gas ixutywe ukuze iqokelele i-mono-, i-di-, i-triethylamine, i-ethanol kunye nezinye izinto ezixutyiweyo, ezithi emva koko zifakwe kwi-rough distillation kunye ne-rectification, kwaye i-54-57°C fraction inqunyulwe kwimveliso egqityiweyo ye-diethylamine. Umxholo wayo unokufikelela ngaphezulu kwe-95%, kwaye inani elincinci le-triethylamine lingafunyanwa ngexesha elinye,
