1. Tetrahydrofuran, lihlahisoa tse sa tsoakoang tsa spandex synthesis, li ka ba tsa polycondensated (ho bula lesale le ho fetisa matla ho qalileng ka cation) ho poly (tetramethylene ether glycol) (PTMEG), e tsejoang hape e le tetrahydrofuran polyether. PTMEG le toluene diisocyanate (TDI) li ne li sebelisetsoa ho etsa rabara e khethehileng ka ho itšireletsa, ho hanyetsa oli, ts'ebetso e ntle ea mocheso o tlase le matla a phahameng, le ho thibela polyether polyester elastic elastic e entsoe ka dimethyl terephthalate le 1,4-butanediol. PTMEG e nang le boima ba limolek'hule tsa 2000 le p-methylene bis (4-phenyl) diisocyanate (MDI) e sebelisoa e le lisebelisoa tse tala tsa fiber ea polyurethane (fiber ea spandex), rabara e khethehileng le liphahlo tse ling tse khethehileng. Ts'ebeliso e kholo ea THF ke ho hlahisa PTMEG. Ho ea ka lipalo-palo tse boima, karolo e fetang 80% ea THF lefats'eng e sebelisoa ho hlahisa PTMEG, 'me PTMEG e sebelisoa haholo ho hlahisa fiber ea spandex elastic. 2.Tetrahydrofuran(THF) ke mokelikeli o tloaelehileng haholo, haholo-holo o loketseng ho qhala PVC, polyvinylidene chloride le butylamine. E sebelisoa haholo e le solvent bakeng sa ho koahela bokaholimo, ho roala li-anticorrosive, enke ea khatiso, theipi le ho roala filimi. E ka laola botenya le khanya ea lera la aluminium ha e sebelisoa ka bate ea aluminium e sa keneleng motlakase. Ho roala litheipi, ho koahela bokaholimo ba PVC, ho hloekisa sekontiri sa PVC, ho tlosa filimi ea PVC, seaparo sa cellophane, enke ea khatiso ea polasetiki, barbotage ea thermoplastic polyurethane, sekhomaretsi se khomarelang, se sebelisoang haholo ho apareng bokaholimo, ho roala, tšireletso, enke, moemeli oa lisebelisoa le moemeli oa kalafo ea letlalo.

3. E sebelisoa e le lisebelisoa tsa lihlahisoa tsa manyolo tse kang meriana. Indastering ea meriana, e sebelisetsoa ho kopanya kebiqing, rifamycin, progesterone le lithethefatsi tse ling tsa lihomone. E ka sebelisoa e le moemeli oa monko (boitsebiso bo kenyelletsang) khase ea mafura le sesebelisoa se ka sehloohong indastering ea meriana.

4. li-solvents tsa chromatographic bakeng sa ts'ebeliso e 'ngoe (gel permeation chromatography) li sebelisoa bakeng sa khase ea tlhaho e nang le tatso, acetylene extractive solvents, polymeric light stabilizers, jj. Ka ts'ebeliso e pharalletseng ea tetrahydrofuran, haholoholo kholo e potlakileng ea indasteri ea spandex Chaena lilemong tsa morao tjena, Tlhokahalo ea PTMEG Chaena e ntse e eketseha letsatsi le letsatsi, 'me tlhoko ea tetrahydrofuran le eona e bonts'a kholo ea kholo.

Litlhokomelo mabapi le polokelo: ka kakaretso lihlahisoa li kenyelletsoa ka polymerization inhibitor. Boloka ka polokelo e pholileng le e nang le moea o kenang moea. Qoba hole le mollo le mohloli oa mocheso. Mocheso oa polokelo ha oa lokela ho feta 30 ℃. Sephutheloana se lokela ho koaloa eseng ho kopana le moea. E lokela ho bolokoa ka thoko le oxidant, acid, alkali, jj. Mabone a bopaki ba ho phatloha le lits'ebeletso tsa moea o kenang li sebelisoa. Ho thibetsoe ho sebelisa lisebelisoa tsa mochini le lisebelisoa tse bonolo ho hlahisa litlhase. Sebaka sa polokelo se tla ba le lisebelisoa tsa kalafo ea maemo a tšohanyetso a dutlang le lisebelisoa tse loketseng tsa polokelo.
