Incazelo:
I-n-Heptane iwuketshezi olucacile oluvutha kakhulu futhi oluguquguqukayo olunephunga elithambile, elifana nelikaphethiloli. Umkhawulo we-Theodor ungama-40-547 ppm; futhi kubikwe ku-230 ppm. Isisindo sama-molecular = 100.23; Amandla adonsela phansi athile (H2O:l) = 0.68; Iphuzu lokubila = 98.39C; UkuqandisaIphuzu lokuncibilika = - 90.6℃; Ingcindezi yomhwamuko = 40 mmHg ku-25℃; Iphuzu lokufiphaza =一4℃;Izinga lokushisa lokusha ngokuzenzakalelayo = 204℃.285℃. Imikhawulo yokuqhuma:LEL= 1.1%; UEL= 6.7%.Ukuhlonza Ingozi (okusekelwe ku-NFPA-704 M Rating System): Impilo 1, Ukusha 3, Ukusabela 0. Akuncibiliki emanzini; ukuncibilika = 0.0003%.

Ukusetshenziswa
Ifanele i-HPLC, i-spectrophotometry, ukuhlolwa kwemvelo
Njengenjwayelekile ekuhlolweni kokungqongqozwa kwezinjini zikaphethiloli.
I-Heptane iyi-solvent kanye ne-ejenti yokunciphisa i-viscosity.
Ukupakisha Nokuthumela
137KG/Isigubhu noma ngokwezidingo zamakhasimende.
Ingaletha ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
