DEA (Diethylamine)

Ma ke ʻano kemika

He wai ʻole kala, lele koke, a lapalapa me kahi ʻala ammonia ikaika. Hiki ke hui pū ʻia me ka wai, ka ethanol, ka ether a me nā mea hoʻoheheʻe organik ʻē aʻe.

Hoʻohana:

He mea hoʻoheheʻe a me nā mea kemika maka waena ka Diethylamine. Hiki ke hoʻohana ʻia e hoʻomākaukau i nā lāʻau lapaʻau e like me procaine, chloroquine, nicosamid, colamin a me sulfonamides. Hiki ke hoʻohana ʻia hoʻi e hana i nā pesticides, dyes, rubber vulcanization accelerators, a pēlā aku. ʻO ka mea hana mineral (sulfur a me ka nitrogen No. 9), nā mea kōkua textile, bactericides, corrosion inhibitors, polymerization inhibitors a me antifreeze agents, a pēlā aku.

ʻano hana

Hoʻohui ke ʻano catalysis pae kinoea kaomi lewa ethanol i ka ethanol pae kinoea, ammonia a me ka hydrogen ma ka lakio o 1:0.8:1.5 (mol), a komo i loko o ka reactor mua i lako me kahi mea hoʻoulu keleawe-nickel ma hope o ka hoʻomehana mua ʻana (170-180°C), ma 195-200°C Hoʻokō ʻia ka hopena catalytic pae kinoea ma 170-175°C, a laila komo i loko o ka lua o ka reactor Chemicalbook me kahi mea hoʻoulu keleawe-nickel no ka hopena synthesis, a hoʻemi ʻia ma 170-175°C e wehe i nā haumia e like me ka acetonitrile. Hoʻopili ʻia ke kinoea hopena e hōʻiliʻili i ka mono-, di-, triethylamine, ethanol a me nā wai i hui pū ʻia, a laila hoʻokomo ʻia i ka distillation rough a me ka hoʻoponopono ʻana, a ʻoki ʻia ka hapa 54-57°C i loko o ka huahana i hoʻopau ʻia o ka diethylamine. Hiki i kona ʻike ke hiki aku ma mua o 95%, a hiki ke loaʻa kahi liʻiliʻi o ka triethylamine i ka manawa like.
