Luv-kev distillation, tseem hu ua molecular distillation, yog kev sib cais siv tshuab uas tau tsim kho sai heev nyob rau hauv xyoo tas los no. Nws tuaj yeem daws cov teeb meem sib cais ntawm cov tshuaj nrog cov tshav kub thiab lub siab kub. Nws yog hu ua distillation, tab sis tus txheej txheem kuj sib txawv. Ordinary distillation tso siab rau qhov sib txawv hauv cov taw tes npau npau, thaum lub suab distillation molecular tso siab rau qhov molecular txhais tau tias yog txoj kev dawb. Kev kawm pub dawb yog dab tsi? Nws yog qhov ncaj nruab nrab ntawm ib lub lwg me thiab lwm lub qauv hauv ob qho kev sib tsoo (qhov kev nkag siab txhais tau tias ntev npaum li cas cov molecule tuaj yeem taug kev los ntawm kev sib hloov thermal). Txoj kev taug txoj kev dawb yog txoj kev xav nruab nrab.
Molecular distillation yog siv rau hauv cov teb ntawm petrochemicals, khoom noj khoom haus, tshuaj, tsw thiab tshuaj tsw qab thiab cov tshuaj zoo, tshwj xeeb tshaj yog nyob rau hauv kev sib cais thiab huv si ntawm cov khoom cua sov. Piv txwv li, qhov kev xav ntawm cov roj ntses rov qab. EPA thiab DHA hauv cov roj ntses (qhov no hu ua lub hlwb kub, thiab ntau cov khoom siv me nyuam mos muaj cov khoom lag luam no) feem ntau yog rho tawm los ntawm roj ntses roj. Cov roj ntses molecularly distilled khoom muaj cov xim zoo thiab tsis muaj cov pa phem peroxide. Cov. Tsis tas li ntawd, cov kev tshem tawm ntawm cov xim, cov vitamins, thiab cov roj tseem ceeb uas hloov tau txhua lub cev siv cov roj molecular distillation. Hauv kev lag luam petrochemical, nws tuaj yeem siv rau kev kho mob ntawm cov roj hluavtaws roj hauv paus, thiab ntxiv rau kev ntsuas roj, thiab yog siv hauv qhov sib sib zog nqus nqus ntawm qhov nqus dej. Hauv thaj teb ntawm kev siv tshuaj, nws yog siv rau kev ua kom huv ntawm cov tshuaj lossis tshuaj nruab nrab (piv txwv, kev ua kom huv ntawm methyl 4-methoxyacetoacetate, qhov tseem ceeb nruab nrab ntawm kev tiv thaiv HIV-1 tshuaj dulutvir).
Kev sib xyaw ntawm molecular distillation thev naus laus zis thiab lwm yam thev naus laus zis tuaj yeem daws teeb meem ntau cov tswv yim. Txawm li cas los xij, kev tshawb nrhiav kev tshawb fawb ntawm cov kua dej sab hauv thiab kev hloov pauv thiab cov txheej txheem hloov mus rau tom tshav kub ntawm cov khoom siv molecular distillation tsis txaus ntseeg. Cov kev tshawb fawb txuas ntxiv yuav tsum tau tsim los tsim cov qauv kev ua lej sib piv los muab cov hauv paus thev txheej txheem rau cov thev naus laus zis molecular distillation thev naus laus zis los daws cov teeb meem tswv yim. Nyob rau tib lub sijhawm, peb yuav tsum tsim kho cov cuab yeej siv qis, kom tau qhov siab tshaj, kom cov thev naus laus zis kev siv tshuab tuaj yeem ua tiav cov ntawv thov kev lag luam loj.
