Kushandiswa kukuru kwen-hexane
N-hexane yakanaka isiri-chepfu organic solvent, inoshandiswa zvakanyanya mukugadzira mafuta emuriwo, butyl, butadiene rubber organic synthesis, propylene, olefin polymerization, mishonga yepakati, pendi yakaonda, uye simbi yekuchenesa pamusoro pemidziyo yemagetsi.

Kubudirira uye kushandiswa kukuru kwen-hexane
Musika mukuru wen-hexane unoshandiswa muindasitiri yemafuta yemiriwo leaching, inoverengera kupfuura 60% yehuwandu hwen-hexane. Zvizhinji zvezvasara zvikumbiro zviri mumaindasitiri erabha nemakemikari.

Kare kuma1960, nyika dzakasimukira dzekuMadokero dzakaita seEurope neUnited States dzaiwanzosimudzira "nzira yekudzidzira" mukugadzirwa kwemafuta emiriwo. Kuwedzera kune mamwe madiki-akawedzera mafuta ekuchera, mafuta epasi anodyiwa anogadzirwa ne "leaching method" atora 95% yemusika. Parizvino, mukugadzirwa kwemafuta anodyika pasi rose, n-hexane ndiyo inonyanya kunyungudutsa pakugadzirwa kwemafuta anodyika. Ehe, nhamba shoma yemakambani emafuta muJapan neSouth Korea anoshandisa isohexane sechinhu chinonyungudutsa.
Kubva mukupera kwema1980s, China yakatanga kusimudzira zvine simba kushandiswa kwen-hexane sechinhu chinonyungudutsa chemafuta emiriwo.
Hunhu hweiyo hexane leaching process: Iyo hexane distillation renji ipfupi, zvinonyungudutsa uye zvinokuvadza zvinhu zvinonyungudutswa zvakazara, mafuta emuriwo zvinovaka muviri haaparadzwe nekupisa kwakanyanya, kuchengetedzwa kwemafuta anodyika kunowedzerwa, uye yakaderera solvent kushandiswa, kwakaderera. zvakasara, goho remafuta akakwira, zviri nyore kugadzirwa kwemaindasitiri.
Parizvino, makambani ekuChina anotsigirwa nemari uye akabatana uye akazvimirira ega ekugadzira oiri anonyanya kushandisa n-hexane sechinhu chinonyungudutsa. Makambani aya anogadzira anopfuura makumi mapfumbamwe muzana emafuta anodyika pamusika wepamba.
Kushandiswa kwen-hexane semafuta emuriwo ekubvisa solvent chinhu chakasimba chinodiwa nehurumende kune inodyika yekugadzira mafuta indasitiri uye zvigadzirwa zvemhando yepamusoro. Naizvozvo, n-hexane yave chigadzirwa chinowanzo shandiswa mukugadziriswa oiri inodyiwa, inova zvakare yepamba uye yekunze hexane mumakore achangopfuura. Kupfuura No. 6 solvent mafuta, butane nezvimwe zvinonyungudutsa zvakava zvakakosha zvakasiyana-siyana zvemafuta emiriwo leaching solvent.
Imwe pfungwa ndeyekuti muindasitiri yekuchera mafuta yemiriwo, n-hexane ine basa rakasiyana uye risingadzoreki. N-hexane ine zita rekuti "mambo wekubvisa". Parizvino, hapana solvent yakakwanisa kudarika n-hexane mukubvisa.
