4-Kev siv Formylmorpholine Thiab Synthesis
Kev piav qhia 4-Formylmorpholine yog ib qho zoo heev uas tsis yog-protonic hnyav. Nws yog dav siv los ua kuab tshuaj thiab extractant rau aromatics. Nws yog siv los ua tshuaj ntxuav tes rau cov kua qaub. Hauv thaj chaw ntawm cov organic synthesis, nws tuaj yeem siv los npaj cov ntawv sau npe 14C, 4-(trifluoromethyl)morpholine, 3-alkyl-2-chloro-5, 6-dihydrobenzaldehyde , triple-biphenyldialdehyde thiab phenylpropargyl aldehyde. Nws ua lub luag haujlwm tseem ceeb hauv desulphurisation ntawm natural gas, syngas, flue gas thiab petrol.
Chemical Properties CLEAR YELLOW LIQUID
N-formylmorpholine yog ib qho tsis muaj xim tsis muaj pob tshab kua soluble hauv dej. Nws yog tshuaj lom neeg ruaj khov, tsis muaj tshuaj lom, thiab tsis muaj corrosive tab sis kuj tuaj yeem yaj aliphatic hydrocarbons, muaj ntxhiab hydrocarbons, thiab dej vim nws cov qauv tshwj xeeb. N-formylmorpholine yuav txo tau qhov volatility ntawm aromatic hydrocarbon thaum dissolving tom kawg. Yog li, nws tuaj yeem rho tawm, distilled thiab rov ua dua cov ntxhiab hydrocarbon. Tsis tas li ntawd, qhov sib xyaw no kuj tseem siv rau hauv C4 (LNG) cov phiaj xwm tawg rau desulfuration thiab hnyav rho tawm, uas tuaj yeem ua rau cov khoom lag luam nce ntxiv (xws li DMF, ACN, thiab NMP txheej txheem). Tam sim no, daim ntawv thov no tau txais hauv Suav teb. Nws yuav tsum tau muab khaws cia rau hauv cov thawv ntim khoom hauv qhov chaw txias, cua txias. Khaws kom deb ntawm hluav taws thiab cua sov. Tsis txhob siv cov cuab yeej siv tshuab uas yuav ua rau cov nplaim taws. Kov maj mam, zam kev puas tsuaj rau lub ntim thiab ntim.
Siv 4-Formylmorpholine yog dav siv los ua cov kuab tshuaj thiab rho tawm cov tshuaj tsw qab. Nws yog siv los ua cov tshuaj txhuam hniav rau cov kua qaub. Nws yog ua haujlwm nyob rau hauv kev npaj ntawm adenine hydrochloride sau nrog 14C, 4-(trifluoromethyl)morpholine, 3-alkyl-2-chloro-5, 6-dihydrobenzaldehyde thiab terphenyl dialdehyde . Nws ua lub luag haujlwm tseem ceeb hauv desulfurization ntawm cov pa roj carbon monoxide, roj hluavtaws, roj flue thiab roj av.
Siv 4-Formylmorpholine tau siv rau hauv kev npaj:

adenine hydrochloride sau nrog14C

terphenyl dialdehyde
