Diethylamine (DEA)

Mankhwala

Ndi madzi opanda mtundu, oyaka moto omwe ali ndi fungo lamphamvu la ammonia. Amasakanikirana ndi madzi, ethanol, ether ndi zinthu zina zachilengedwe.

Kagwiritsidwe:

Diethylamine ndi mankhwala osungunuka komanso mankhwala. Ingagwiritsidwe ntchito popanga mankhwala monga procaine, chloroquine, nicosamid, colamin ndi sulfonamides. Ingagwiritsidwenso ntchito popanga mankhwala ophera tizilombo, utoto, zothamangitsa rabara, ndi zina zotero. Wothandizira kukonza mchere (sulfure ndi nayitrogeni Nambala 9), othandizira nsalu, mabakiteriya, zoletsa dzimbiri, zoletsa polymerization ndi zoletsa kuzizira, ndi zina zotero.

njira yopangira

Njira yopangira mpweya wa ethanol mumlengalenga imasakaniza ethanol, ammonia ndi haidrojeni pa chiŵerengero cha 1:0.8:1.5 (mol), ndipo imalowa mu reactor yoyamba yokhala ndi chothandizira cha mkuwa-nickel pambuyo potenthetsera (170-180°C), pa 195-200°C. Chothandizira cha mpweya chimachitika pa 170-175°C, kenako chimalowa mu reactor yachiwiri Chemicalbook yokhala ndi chothandizira cha mkuwa-nickel kuti chigwirizane ndi kapangidwe kake, ndipo chimachepetsedwa pa 170-175°C kuti chichotse zonyansa monga acetonitrile. Mpweya wochitapo kanthu umafupikitsidwa kuti utenge mono-, di-, triethylamine, ethanol ndi zakumwa zina zosakaniza, zomwe kenako zimaphikidwa ndi kukonzedwa, ndipo gawo la 54-57°C limadulidwa kukhala chinthu chomalizidwa cha diethylamine. Zomwe zili mkati mwake zimatha kufika pa 95%, ndipo triethylamine yochepa ingapezeke nthawi yomweyo,
