Tšebeliso ea Sehlahisoa:
1.Ho phaella ho organic synthesis, sehlahisoa sena se boetse se sebelisoa haholo e le filimi ea cellulose acetate, cellulose triacetate pumping, petroleum dewaxing, solvents tlhahiso ea li-aerosols le lithibela-mafu, livithamine, metsoako ea steroidal, hammoho le ho hloekisa le ho hloekisa holim'a tšepe holim'a lacquer le e tlosang filimi.
2.E sebelisoa ho fumigation ea lijo-thollo le sehatsetsing sa lihatsetsi tse nang le khatello e tlase le li-air-conditioning units.E sebelisoa e le ntho e thusang ho fefola ha ho etsoa foam ea polyether urethane hape e le ntho e fokang bakeng sa foam ea polysulfone e extruded.
3.E sebelisoa e le solvent, extractant le mutagen.E sebelisoa lipatlisisong tsa lefutso la limela.
4.E na le solvency e ntle, ke mokelikeli o tlaase o belang o nang le chefo e nyenyane le e sa cheng har'a li-solvents tsa indasteri tse sebelisoang hangata, 'me e na le solvency e ntle bakeng sa li-resin tse ngata, parafine le mafura.Haholo-holo e sebelisoa e le sesepa sa pente, motsoako oa petroleum dewaxing, extractant ea lintho tse sa tsitsang tsa mocheso, ho ntša lanolin boea le oli e jeoang ho tloha kokonate, solvent ea cellulose triacetate filimi.E boetse e sebelisoa haholo ho acetate fiber, tlhahiso ea fiber ea vinyl chloride, ho sebetsa le litima-mollo, lihatsetsi, urotropine le lihlahisoa tse ling.
5.E sebelisoa indastering ea elektroniki.Hangata e sebelisoa e le sesebelisoa sa ho hloekisa ho tlosa oli.
6.E sebelisoa haholo e le mokelikeli o thibelang mollo o nang le ntlha e tlaase haholo e belang.Ntle le ho hlatsoa metsoako ea lienjine tsa lifofane, mechini e nepahetseng, joalo-joalo, e ka boela ea sebelisoa e le sesebelisoa sa ho hlobola lipente, hape e ka tsoakoa le metsoako e meng e tla sebelisoa mefuteng e fapaneng ea ho hlatsoa liindasteri.
7.Hape e sebelisoa e le ethyl ester fiber solvent, anesthesia ea sebakeng sa meno, sehatsetsi le setima-mollo, joalo-joalo, ke ntho e tloaelehileng ea ho arohana ha chromatographic le karohano ea ho ntša lihlahisoa tse tloaelehileng.
8.E sebelisoa e le solvent indastering ea resin le polasetiki.
Lintlha tsa polokelo ea Sehlahisoa:
1.E boloke sebakeng sa polokelo se pholileng, se nang le moea o pholileng.
2.Kena hole le mollo le mohloli oa mocheso.
3. Boloka mocheso o sa feteng 32°C le mongobo o lekanyelitsoeng o sa feteng 80%.
4. Boloka setshelo se tiisitsoe.
5.E lokela ho bolokoa ka thoko ho litšepe tsa alkali le lik'hemik'hale tse jeoang, 'me le ka mohla ha ea lokela ho tsoakoa.
6.E na le mefuta e nepahetseng le bongata ba lisebelisoa tsa ho tima mollo.
7.Sebaka sa polokelo se lokela ho ba le lisebelisoa tsa phekolo ea tšohanyetso tse lutlang le lisebelisoa tse loketseng tsa bolulo.
