Pentane. Zvimiro zvayo ndezvizvi:

Inosanganiswa nemafuta akawanda anonyungudutsa asi kwete nemvura.

Chemical Properties: N-pentane is aliphatic hydrocarbon iyo inopfuta uye ine yakaderera flash point uye autoignition tembiricha. Inogona kupiswa mumhepo kuti ibudise carbon dioxide nemvura. Chimiro chayo chiri nyore, uye n-pentane inoshanda neyakajairwa organic komisheni.

Zvishandiso: N-pentane inoshandiswa zvakanyanya mukuyedza kwemakemikari, kugadzirira kwezvinonyungudutsa uye zvinonyungudutsa zvinosanganiswa, uye zvakare chinhu chakakosha mbishi muindasitiri yepetroleum.

Kugadzirira nzira: n-pentane inonyanya kuwanikwa kuburikidza nekuputika nekugadzirisa mune petroleum refining process. Iyo petroleum-yakagadzirwa nemaitiro aya ine n-pentane, iyo inogona kuparadzaniswa uye kucheneswa ne distillation kuti iwane yakachena n-pentane.

Ruzivo rwekuchengetedza: n-pentane imvura inopisa uye inofanirwa kuchengetedzwa kure nemirazvo yakavhurika uye tembiricha yakakwira. Inofanirwa kushandiswa munzvimbo inofefetera zvakanaka uye kudzivirira kusangana neakasimba oxidizing agents. Kuratidzwa kwenguva refu kune n-pentane kunogona kukonzera ganda rakaoma uye rinoputika, uye matanho akakodzera ekudzivirira akadai semagirovhosi nemagogi anofanira kutorwa. Muchiitiko chekufemerwa netsaona kana kubata ganda nen-pentane, tsvaga rubatsiro rwekurapa nekukurumidza.
