Inkcazo:
I-n-Heptane lulwelo olucacileyo oluvutha kakhulu kwaye luguquguqukayo olunevumba elithambileyo, elifana nepetroli. Umlinganiselo we-Theodor yi-40-547 ppm; ikwaxelwe kwi-230 ppm. Ubunzima be-molecular = 100.23; Ubunzima obuthile (H2O:l) = 0.68; Iqondo lokubila = 98.39C; Ukuqandisa Inqanaba lokunyibilika = - 90.6℃; Uxinzelelo lomphunga = 40 mmHg kwi-25℃; Inqaku lokutsha =一4℃;Ubushushu bokutsha okuzenzakalelayo = 204℃ .285℃. Imida yokuqhuma: LEL= 1.1%; UEL= 6.7%.Ukuchonga iNgozi (ngokusekwe kwiNkqubo yoHlelo lweNFPA-704 M): Impilo 1, Ukutsha 3, Ukusabela kwakhona 0. Ayinyibiliki emanzini; ukunyibilika = 0.0003%.

Ukusetyenziswa
Ifanelekile kwi-HPLC, i-spectrophotometry, uvavanyo lokusingqongileyo
Njengomgangatho oqhelekileyo wokuvavanya ukungqongqozwa kweenjini zepetroli.
I-Heptane sisinyibilikisi kunye ne-arhente yokunciphisa i-viscosity.
Ukupakishwa kunye nokuthunyelwa
137KG/Idrama okanye ngokweemfuno zomthengi.
Ingahambisa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
