Taw qhia
Khoom:
Propylphosphonic anhydride yog xim tsis muaj xim rau lub teeb daj sib xyaw ntawm propane raws li phosphonic anhydride chav kawm. Nws yog cov dej-soluble compound uas tuaj yeem yaj hauv dej los tsim cov tshuaj. Nws yog cov kua nyob rau hauv chav tsev kub thiab muaj ib tug pungent tsw.
Kev siv:
Propylphosphonic anhydride feem ntau yog siv los ua cov tshuaj tiv thaiv corrosion, nplaim taws retardant, thiab ntxiv rau hauv cov dej ua haujlwm hlau hauv kev tsim khoom. Nws kuj yog siv nyob rau hauv lub teb ntawm biomedicine.
Synthesis:
Propylphosphonic anhydride tuaj yeem tsim los ntawm cov tshuaj tiv thaiv ntawm phosphorus oxychloride nrog propylene glycol.
Kev nyab xeeb:
Propylphosphonic anhydride muaj kev nyab xeeb siab, tab sis tseem yuav tsum tau ceev faj. Kev sib cuag nrog daim tawv nqaij los yog nqus tau cov ntsiab lus siab ntawm propylphosphonic anhydride tuaj yeem ua rau khaus thiab tsis xis nyob, yog li nws yuav tsum zam kom tsis txhob kis tau ntev. Cov cuab yeej tiv thaiv tsim nyog yuav tsum tau hnav thaum siv, thiab ib puag ncig yuav tsum muaj qhov cua zoo. Kev pheej hmoo rau tib neeg kev noj qab haus huv thiab ib puag ncig tuaj yeem txo qis los ntawm kev ua haujlwm kom raug thiab kev khaws cia.
