quality
Mvura isina ruvara inoputika. Isoluble mumvura, soluble mudoro, miscible mu ether, chloroform. Hupfu hwayo hunoumba musanganiswa unoputika nemhepo, izvo zvinokonzeresa kupisa uye kuputika kana murazvo wakavhurika uye kupisa kwakanyanya simba. Inogona kuita zvakasimba neoxidants.

Nzira
Iyo indasitiri-giredhi n-heptane inogona kucheneswa neyakaomeswa sulfuric acid washing, methanol azeotropic distillation uye dzimwe nzira.

use
Inoshandiswa seye analytical reagent, peturu injini kugogodza bvunzo standard, chinhu chinongedzo chekuongorora chromatographic, uye solvent. Inoshandiswa seyero yekumisikidzwa kwenhamba yeoctane, uye inogona zvakare kushandiswa sechinhu chinodhaka, chinonyungudutsa uye mbishi zvinhu zveorganic synthesis.

kuchengeteka
mbeva intravenous jekiseni LD50: 222mg/kg; mbeva yakafemerwa 2h LCso: 75000mg/m3. Chinhu ichi chinokuvadza zvakatipoteredza, chinogona kukonzera kusvibiswa kwemitumbi yemvura nemhepo, uye bioaccumulates mumaketani anokosha ezvokudya zvevanhu, kunyanya muhove. Heptane inogona kukonzera dzungu, kusvotwa, anorexia, kufamba kunoshamisa, uye kunyange kurasikirwa nekuziva uye kurara. Chengetedza muimba yekuchengetera inotonhorera, ine mhepo. Kunyanya kubatwa nemoto. Ramba kure nemoto nekupisa. Iyo tembiricha yekuchengetera zvinhu haifanire kudarika 30 ° C. Dzivirira kubva kuzuva rakananga. Chengetedza mudziyo wakavharwa zvakasimba. Inofanira kuchengetwa zvakasiyana kubva kune oxidizing agent.
