Heptane (CAS # 142-82-5)

zoo
Colorless volatile kua. Insoluble hauv dej, soluble hauv cawv, miscible hauv ether, chloroform. Nws cov vapor tsim ib qho kev sib tov sib xyaw nrog huab cua, uas ua rau combustion thiab tawg nyob rau hauv cov ntaub ntawv ntawm qhib nplaim taws thiab siab kub zog. Nws tuaj yeem cuam tshuam nrog oxidants.

Txoj kev
Kev lag luam qib n-heptane tuaj yeem ua kom huv los ntawm kev siv tshuaj sulfuric acid ntxuav, methanol azeotropic distillation thiab lwm txoj kev.

siv
Nws yog siv los ua cov tshuaj analytical reagent, roj av cav khob qhov ntsuas tus qauv, cov khoom siv rau chromatographic tsom xam, thiab hnyav. Nws yog siv los ua tus qauv rau kev txiav txim siab ntawm tus lej octane, thiab tseem tuaj yeem siv los ua cov tshuaj lom neeg, hnyav thiab cov khoom siv raw rau cov organic synthesis.

kev ruaj ntseg
nas txhaj tshuaj LD50: 222mg/kg; nas inhaled 2h LCso: 75000mg/m3. Cov khoom no muaj kev phom sij rau ib puag ncig, tuaj yeem ua rau muaj kuab paug rau lub cev dej thiab cua, thiab bioaccumulates hauv cov khoom noj tseem ceeb rau tib neeg, tshwj xeeb tshaj yog nyob rau hauv cov ntses. Heptane tuaj yeem ua rau kiv taub hau, xeev siab, anorexia, staggering gait, thiab txawm tsis nco qab thiab stupor. Khaws rau hauv qhov chaw txias, ventilated warehouse. Tsis tshua muaj hluav taws kub. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov. Lub tsev khaws khoom kub yuav tsum tsis pub tshaj 30 ° C. Tiv thaiv los ntawm tshav ntuj ncaj qha. Khaws lub thawv ntim kom nruj. Nws yuav tsum tau muab cais los ntawm tus neeg sawv cev oxidizing.
