Taw qhia
2-ethoxy-3-isopropylpyrazine yog ib qho organic compound.
Lub compound muaj cov khoom nram qab no:
- Cov tsos: cov kua tsis muaj xim
- Solubility: Soluble hauv ethanol, ether thiab benzene, insoluble hauv dej
2-ethoxy-3-isopropylpyrazine muaj qee qhov kev siv tshwj xeeb:
- Nws tuaj yeem siv los ua tshuaj tua kab hauv kev ua liaj ua teb. Hauv kev tiv thaiv qoob loo, nws tuaj yeem siv los tswj cov kab tsuag xws li planthoppers hauv cov teb qhuav.
- Nws kuj yog feem ntau siv rau hauv cov organic synthesis raws li catalyst thiab nruab nrab.
Txoj kev npaj ntawm 2-ethoxy-3-isopropylpyrazine tuaj yeem tau txais los ntawm cov kauj ruam hauv qab no:
1. 2-Pyridylcarboxylic acid thiab isopropyl bromide reacted nyob rau hauv lub catalysis ntawm lub hauv paus los tsim 2-isopropylpyridine.
2. 2-Isopropylpyridine yog reacted nrog ethanol nyob rau hauv acidic tej yam kev mob los tsim 2-ethoxy-3-isopropylpyrazine.
- Nws yog khaus thiab corrosive, thiab yuav tsum tau yaug nrog dej ntau tam sim ntawd tom qab sib cuag nrog daim tawv nqaij thiab qhov muag.
- Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li tsom iav kev nyab xeeb, hnab looj tes thiab khaub ncaws tiv thaiv yuav tsum tau siv.
- Thaum lub sijhawm khaws cia thiab kev thauj mus los, kev cuam tshuam nrog cov oxidants muaj zog thiab cov kua qaub yuav tsum zam, qhov kub thiab txias yuav tsum raug zam.
