Intshayelelo

iPentane. Iimpawu zayo zezi zilandelayo:

Iyaxubana nezinyibilikisi ezininzi eziphilayo kodwa hayi ngamanzi.

Iipropati zeMichiza: I-N-pentane yi-aliphatic hydrocarbon enokutsha kwaye inomlinganiselo ophantsi we-flash point kunye nokushisa okuzenzekelayo. Inokutshiswa emoyeni ukuvelisa ikharbon diokside namanzi. Isakhiwo sayo silula, kwaye i-n-pentane iyasebenza kunye neyona nto ixhaphakileyo ye-organic compounds.

Ukusetyenziswa: I-N-pentane isetyenziswa ngokubanzi kwiimvavanyo zemichiza, ukulungiswa kwe-solvents kunye nemixube ye-solvent, kwaye iyinto ebalulekileyo ekrwada kwishishini lepetroleum.

Indlela yokulungiselela: i-n-pentane ifumaneka ikakhulu ngokuqhekeka kunye nokuguqulwa kwenkqubo yokucoca i-petroleum. Iimveliso zepetroleum eziveliswa ngezi nkqubo ziqulethe i-n-pentane, enokuthi ihlulwe kwaye ihlanjululwe nge-distillation ukuze ifumane i-n-pentane ecocekileyo.

Ulwazi ngokhuseleko: I-n-pentane lulwelo olunokutsha kwaye kufuneka lugcinwe kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu. Kufuneka isetyenziswe kwindawo enomoya ococekileyo kwaye ugweme ukudibanisa nee-oxidizing agents ezinamandla. Ukubonakaliswa kwexesha elide kwi-n-pentane kunokubangela ukuba isikhumba esomileyo nesicaphukileyo, kwaye amanyathelo afanelekileyo okukhusela afana neeglavu kunye neeglavu kufuneka athathwe. Kwimeko yokuphefumla ngempazamo okanye ukudibana kwesikhumba ne-n-pentane, funa uncedo lwezonyango ngokukhawuleza.

Ngaphambili: Heptane(CAS#142-82-5)

Okulandelayo: I-Octane(CAS#111-65-9)
