Taw qhia
Methyl 3-oxocyclopentacarboxylic acid. Cov hauv qab no yog cov lus qhia luv luv rau cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw:
Zoo:
- Methyl 3-oxocyclopentacarboxylic acid yog cov kua tsis muaj xim uas tsis muaj dej solubility.
- Nws muaj qee yam flammability, thiab combustion tej zaum yuav tshwm sim thaum nws los rau hauv kev sib cuag nrog lub ignition qhov chaw.
- Cov khoom sib xyaw yog cov kua hluav taws xob uas nws cov vapors tuaj yeem tsim cov nplaim hluav taws lossis tawg sib xyaw.
Siv:
- Methyl 3-oxocyclopentacarboxylic acid feem ntau yog siv los ua cov kuab tshuaj thiab tuaj yeem siv los yaj qee cov organic teeb meem.
Txoj kev:
- Methyl 3-oxocyclopentacarboxylic acid feem ntau yog npaj los ntawm cov tshuaj tiv thaiv esterification, thiab cov kev npaj tshwj xeeb tuaj yeem ua ke los ntawm cov tshuaj tiv thaiv cawv thiab kua qaub.
Cov ntaub ntawv kev nyab xeeb:
- Methyl 3-oxocyclopentacarboxylate yog cov organic sib xyaw ua ke, thiab yuav tsum tau ceev faj thaum siv.
- Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag thaum siv kom tsis txhob muaj qhov khaus lossis raug mob.
- Kev ua pa zoo yuav tsum tau khaws cia thaum tuav cov khoom sib xyaw.
- Nws yog ib qho hluav taws kub, thiab yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog qhov hluav taws kub tiv thaiv qhov tshwm sim ntawm hluav taws thiab tawg.
- Thaum khaws cia thiab tuav cov khoom sib xyaw, cov txheej txheem kev nyab xeeb thiab kev tswj hwm yuav tsum tau ua raws.
