3. Cov Qauv Ntau Lawm
Thawj qhov chaw: muab tau los ntawm Platinum - dua naphha (93-102 degree}} hephane constitestes ~ 57% ntawm distillate. Purification cuam tshuam:
5a molecular sab cib adsorption rau cais tawm linear alkanes.
Nickel -} catalalyzed hydrogenation kom tshem olefins (iodine tus nqi<0.1 g I₂/100g).
Distillation kom ua tiav ntau dua los yog sib npaug rau 99.9% Purity 13.
Cov hau kev no: cov sulfuric acid ntxuav, methanol azeotropic distillation, lossis oxidative ua raws li cov khoom siv cov roj carbon adsorption 3.
