Diethylamine (DEA)

Zvemakemikari

Imvura isina ruvara, inopfuta uye inobvira ine hwema hwakasimba hweammonia. Inosanganiswa nemvura, ethanol, ether nezvimwe zvinonyungudutsa.

Mashandisirwo:

Diethylamine chinhu chinonyungudutsa uye chinoshandiswa mumakemikari. Chinogona kushandiswa kugadzira mishonga yakaita seprocaine, chloroquine, nicosamid, colamin uye sulfonamides. Chinogona kushandiswawo kugadzira mishonga yekuuraya zvipembenene, madhayi, zvinokurumidzisa rabha, nezvimwewo. Mineral processing agent (sulfur nenitrogen Nhamba 9), machira anobatsira, mabhakitiriya, zvinodzivisa ngura, zvinodzivisa polymerization uye zvinodzivirira kutonhora, nezvimwewo.

nzira yekugadzira

Nzira yeEthanol atmospheric pressure gas phase catalysis inosanganisa gas phase ethanol, ammonia nehydrogen pachiyero che1:0.8:1.5 (mol), uye inopinda mureactor yekutanga ine copper-nickel catalyst mushure mekudziya (170-180°C), pa195-200°C. Gas-phase catalytic reaction inoitwa pa170-175°C, uye yobva yapinda mu reactor yechipiri Chemicalbook ine copper-nickel catalyst yekugadzira reaction, uye inoderedzwa pa170-175°C kubvisa tsvina yakaita seacetonitrile. Gas reaction inounganidzwa kuti iunganidze mono-, di-, triethylamine, ethanol nedzimwe mvura dzakasanganiswa, izvo zvinozoiswa mu rough distillation uye rectification, uye 54-57°C fraction inochekwa kuita chigadzirwa chakapedzwa che diethylamine. Zvirimo zvayo zvinogona kusvika kupfuura 95%, uye huwandu hushoma hwe triethylamine hunogona kuwanikwa panguva imwe chete,
