Heptane(CAS#142-82-5)
umgangatho
Ulwelo oluguquguqukayo olungenambala. I-insoluble emanzini, i-soluble e-alcohol, i-miscible kwi-ether, i-chloroform. Umphunga wayo wenza umxube oqhumayo kunye nomoya, obangela ukutsha kunye nokudubula kwimeko yomlilo ovulekileyo kunye namandla obushushu aphezulu. Inokusabela ngamandla kunye nee-oxidants.
Indlela
I-industrial-grade n-heptane inokuhlanjululwa ngokuxutywa kwe-sulfuric acid washing, i-methanol azeotropic distillation kunye nezinye iindlela.
sebenzisa
Isetyenziswa njenge-reagent yokuhlalutya, umgangatho wokuvavanya injini yepetroli, into ekubhekiselwa kuyo kuhlalutyo lwechromatographic, kunye nesinyibilikisi. Isetyenziswe njengomgangatho wokumiselwa kwenombolo ye-octane, kwaye ingasetyenziselwa njengento enxilisayo, i-solvent kunye ne-raw material ye-organic synthesis.
ukhuseleko
inaliti ngempuku emithanjeni LD50: 222mg/kg; impuku irhogelwe 2h LCso: 75000mg/m3. I-substance iyingozi kwindalo esingqongileyo, inokubangela ungcoliseko kwimizila yamanzi kunye ne-atmosfera, kwaye i-bioaccumulates kumakhonkco okutya abalulekileyo kubantu, ngakumbi kwiintlanzi. I-Heptane inokubangela ukuba ube nesiyezi, isicaphucaphu, i-anorexia, ukuhamba ngendlela eyothusayo, kwanokulahlekelwa zingqondweni nokuba nomsindo. Gcina kwindawo epholileyo nengena umoya. Isesichengeni kakhulu sokutsha. Zigcine kude nomlilo kunye nemithombo yobushushu. Ubushushu bendawo yokugcina impahla akufunekanga budlule kwi-30°C. Khusela ilanga elithe ngqo. Gcina isitya sivalwe ngokuqinileyo. Kufuneka igcinwe ngokwahlukileyo kwi-agent oxidizing.
