Tetrahydrothiophene yog siv dav hauv cov kav dej hauv nroog, suav nrog cov roj av thiab cov roj liquefied roj av (LPG). Kev lag luam cov qauv xav kom cov concentration ntawm tetrahydrothiophene ntxiv rau cov roj yuav tsum tswj ntawm 16-25 mg / m³ kom ntseeg tau tias tib neeg lub cev tseem tuaj yeem ntes nws los ntawm kev hnov tsw txawm tias qhov concentration nce mus txog 1/5 ntawm qhov qis qis (kwv yees li 0.2% los ntawm ntim). Piv txwv li, ib lub tuam txhab roj av hauv ib lub nroog ntxiv 18 mg / m³ rau cov pa roj hauv tsev, thaum nce ntxiv rau 22 mg / m³ rau cov roj av vim qhov ntim loj dua.
Hauv kev tsim khoom, cov txheej txheem synthesis ntawm tetrahydrothiophene ncaj qha cuam tshuam rau tus nqi. Cov txheej txheem tseem ceeb yog txoj kev thiophene catalytic hydrogenation, uas yuav tsum tau siv cov nickel-raws li catalysts nyob rau hauv qhov kub thiab txias (xws li, kub 200-}250 degree, siab 5-10 MPa). Cov khoom siv raw muaj xws li thiophene, hydrogen, thiab cov kuab tshuaj, thiab cov cuab yeej siv peev nyiaj rau kwv yees li 40% ntawm cov nqi tsim khoom. Lwm txoj kev, thiol oxidation txoj kev, txawm hais tias siv cov ntaub ntawv raw khoom yooj yim, ua rau ntau cov khoom lag luam thiab tsis yooj yim rau kev tswj hwm ntawm purity, thiab feem ntau yog siv hauv khw muag khoom qis.
