Taw qhia
2-Ethoxypyrimidine yog ib qho organic compound.
2-Ethoxypyrazine yog cov kua tsis muaj xim uas muaj ntxhiab tsw me ntsis. Nws yog tsawg soluble hauv dej tab sis soluble nyob rau hauv feem ntau cov organic solvents.
2-ethoxypyrazine kuj tseem siv tau los ua tshuaj tua kab thiab tshuaj tua kab mob. Nws ntau yam kev siv tshuaj lom neeg ua rau nws yog ib qho tseem ceeb hauv kev tshawb fawb thiab kev lag luam.
Txoj kev npaj 2-ethoxypyrazine feem ntau tau txais los ntawm cov tshuaj tiv thaiv ntawm 2-aminopyrazine thiab ethanol. Thaum lub sijhawm ua haujlwm tshwj xeeb, 2-aminopyrazine yog yaj hauv ethanol, thiab tom qab ntawd dilute hydrochloric acid maj mam ntxiv dropwise, thiab tshaj ethanol ntxiv. Cov tshuaj yog distilled kom qhuav kom tau 2-ethoxypyrazine khoom.
2-Ethoxypyrazine yog khaus thiab tiv nrog daim tawv nqaij, qhov muag, thiab ua pa ib ntsuj av. Hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab qhov ncauj qhov ntswg thaum tuav. Kev saib xyuas yuav tsum tau muab khaws cia 2-ethoxypyrazine nyob rau hauv qhov chaw qhuav, txias, deb ntawm ignition thiab oxidants. Cov txheej txheem ua haujlwm kom raug thiab kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua raws li thaum siv lossis tuav cov khoom sib xyaw no.
