Gukoresha cyane n-hexane
N.

Iterambere hamwe nuburyo bukoreshwa bwa n-hexane
Isoko nyamukuru rya n-hexane rikoreshwa mu nganda zikomoka ku mavuta y’ibimera, zingana na 60% by’amafaranga yose ya n-hexane. Ibyinshi mubisigaye bisigaye biri mubikorwa bya rubber na chimique.

Nko mu myaka ya za 1960, ibihugu byateye imbere muburengerazuba nku Burayi na Amerika muri rusange byateje imbere "uburyo bwo gutobora" mu musaruro w’amavuta akomoka ku bimera. Usibye gukuramo peteroli ntoya, amavuta aribwa ku isi yakozwe n "uburyo bwo guhisha" yatwaye 95% ku isoko. Kugeza ubu, mu musaruro mpuzamahanga w’amavuta aribwa, n-hexane niyo nzira nyamukuru yo gutunganya amavuta yo kurya. Birumvikana ko umubare muto wibigo bya peteroli mubuyapani na koreya yepfo bikoresha isohexane nkigisubizo cyo gukuramo.
Kuva mu mpera z'imyaka ya za 1980, Ubushinwa bwatangiye guteza imbere cyane ikoreshwa rya n-hexane nk'umuti wo gukuramo amavuta y'ibimera.
Ibiranga uburyo bwo kumena hexane: Urwego rwa distillation ya hexane ni rugufi, ibintu byangiza kandi byangiza bihindagurika neza, intungamubiri zamavuta yimboga ntizisenywa nubushyuhe bwinshi, umutekano wamavuta aribwa wongerewe imbaraga, hamwe no gukoresha ibishishwa bike, bike ibisigara, umusaruro mwinshi wa peteroli, byoroshye kubyara umusaruro mwinshi.
Kugeza ubu, abashinwa baterwa inkunga n’abashoramari bo mu gihugu hamwe n’abashoramari hamwe n’ibigo byigenga bikomoka kuri peteroli biribwa ahanini bakoresha n-hexane nk'umuti wangiza. Izi sosiyete zitanga ibice birenga 90% byamavuta aribwa ku isoko ryimbere mu gihugu.
Gukoresha n-hexane nk'umusemburo ukomoka ku bimera bikomoka ku bimera ni ikintu gisabwa na leta ku nganda zitunganya amavuta aribwa ndetse n'ubuziranenge bw'ibicuruzwa. Kubwibyo, n-hexane yahindutse ibicuruzwa bisanzwe bikoreshwa mugutunganya amavuta aribwa, ari nayo hexane yo murugo no mumahanga mumyaka yashize. Kurenza No 6 amavuta yumuti, butane nandi mashanyarazi yabaye ubwoko bwingenzi bwamavuta yimboga.
Indi ngingo ni uko mu nganda zikuramo amavuta y’ibimera, n-hexane ifite uruhare rwihariye kandi rudasimburwa. N-hexane ifite izina rya "umwami wo gukuramo". Kugeza ubu, nta muti washoboye kurenga n-hexane mugukuramo.
