Yog paraxylene kua muaj teeb meem?

Khoom npe: paraxylene
Tus lej lej: 106-42-3
Molecular Cov Qauv: C8H10
Cov tsos thiab cov khoom: ib qho tsis muaj kob, cov kua pob tshab nrog cov ntxhiab tsw ntxhiab tsw ntxhiab thiab qab zib ntawm chav sov; Nws crystallizes ntawm tsawg kub.
Solubility: tsis zoo soluble hauv dej (solubility hauv dej ntawm 25℃yog 165 mg / l); ua kom tsis meej nrog ntau cov kuab tshuaj muaj zog xws li ethanol, diethyl ether, acetone, thiab benzene; soluble hauv chloroform.

Paraxylene / P {-} {} TereChalic Raw Khoom (PTYENT), tab sis kuj tuaj yeem siv los ua cov kuab tshuaj thiab tshuaj, tsw qab, number cas thiab lwm yam lag luam ntawm cov khoom siv raw.

Paraxylene (P {-} {{{{- 42-3) yog qhov muaj kev phom sij, thiab muaj kev phom sij ntev.

Kev phom sij thiab kev nyab xeeb:
Flammability: nws yog cov kua hluav taws nrog cov kua nrog lub ntsej muag ntawm 27℃(81℃f). Nws cov vapors tuaj yeem tsim cov khoom sib xyaw nrog huab cua.
Cov teebmeem kev noj qab haus huv: nqus tau cov pa vaum tuaj yeem ua rau ua pa tawm, kiv taub hau, mob taub hau, thiab nruab nrab ntawm cov hlab ntshav siab (narcotic teebmeem). Nws tuaj yeem ua iffite daim tawv nqaij thiab qhov muag thaum sib cuag thiab tuaj yeem ua rau muaj mob dermatitis los ntawm kev tawm tsam daim tawv nqaij.
Kev cuam tshuam ib puag ncig: nws yog tshuaj lom rau dej yug tsiaj.
Ceev faj: Kev tuav tes yuav tsum muaj qhov cua muaj txiaj ntsig (feem ntau yog lub ntsej muag zoo), tshuaj lom {{{{{{{}} Cov hnab looj tes tiv hnab looj tes, thiab kev tiv thaiv kev nyab xeeb. Cia yuav tsum yog nyob rau hauv qhov txias, zoo- pa thaj chaw deb ntawm thaj chaw zes.
