KAYAMBIDWE:
Kufotokozera:
n-Heptane ndi madzi oyera omwe amatha kuyaka kwambiri komanso kusinthasintha ndi fungo lofatsa ngati la petulo. Mlingo wa fungo ndi 40-547 ppm; komanso akuti ndi 230 ppm. Kulemera kwa molekyulu = 100.23; Mphamvu yokoka (H2O:l) = 0.68; Malo otentha = 98.39C; Kuzizira Malo osungunuka = - 90.6℃; Kuthamanga kwa nthunzi = 40 mmHg pa 25℃; Malo owunikira =一4℃;Kutentha kwa Autoignition = 204℃.285℃. Malire Ophulika:LEL= 1.1%; UEL= 6.7%.Kuzindikira Zoopsa (kutengera NFPA-704 M Rating System): Thanzi 1,Kuyaka 3, Kuchitapo Kanthu 0. Sisungunuka m'madzi;kusungunuka = 0.0003%.

Kagwiritsidwe Ntchito
Yoyenera HPLC, spectrophotometry, ndi kuyesa zachilengedwe
Monga muyezo poyesa kugwedezeka kwa injini za petulo.
Heptane ndi mankhwala osungunulira komanso ochepetsa kukhuthala kwa thupi.
Kulongedza ndi Kutumiza
137KG/Drum kapena malinga ndi zomwe kasitomala akufuna.
Ikhoza kuperekedwa ndi nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
