Heptane ialkane yakajairika yakatwasuka ine fomura yemakemikari C₇H₁₆, iyo inoumba chimiro chemakemikari chakasimba kuburikidza nezvisungo zvimwechete zvinobatanidza maatomu manomwe ekabhoni nemaatomu gumi nematanhatu ehydrogen.
Kana tichitarisa hunhu hwemuviri, heptane imvura isina ruvara uye inoonekera ine hwema hushoma. Pokufashaira kwayo inenge 98.4 degrees Celsius, pokunyunguduka kwayo -90.6 degrees Celsius, uye density yayo ishoma pane yemvura, inenge 0.684 gramu pa cubic centimeter pa20 degrees Celsius. Heptane hainyungudike mumvura asi inonyungudika nyore nyore mu organic solvents dzakadai se ethanol ne ether.
Sechinhu chakakosha chemakemikari, heptane inoshandiswa zvakasiyana-siyana mumarabhoritari nemumaindasitiri. Inowanzo shandiswa se organic solvent kunyungudutsa zvinhu zvakaita semafuta, rabha, uye resin; mukuongorora makemikari, heptane inogona kushandiswa sechinhu chakajairika chekuenzanisa zvishandiso uye kuona kururama kwenzira dzekuongorora.
Zvinofanira kucherechedzwa kuti heptane inobvira moto, uye utsi hwayo hunogona kugadzira musanganiswa unoputika nemhepo, izvo zviri nyore kupisa nekuputika kana zvasangana nemoto wakavhurika uye kupisa kwakanyanya. Saka, panguva yekuchengetera nekushandisa, zvakakosha kuchengetedza kure nezvinodzima moto nezvinodzima moto, kuchengetedza mhepo yakanaka, uye kutora matanho akakodzera ekudzivirira moto nekuputika kuti uve nechokwadi chekuti zvakachengeteka.
