Cov khoom siv hydrocarbon yog cov chav kawm tseem ceeb ntawm cov kuab tshuaj, tab sis lawv cov kev xaiv yuav tsum muaj kev xav txog kev solubility, kev nyab xeeb, thiab ib puag ncig. Hauv kev siv cov tswv yim, nws raug pom zoo kom ua qhov tseem ceeb tsawg - tshuaj lom los yog cov kuab tshuaj zoo ib puag ncig thiab ua raws li cov txheej txheem ua haujlwm nruj me ntsis.
Cov cheeb tsam tseem ceeb ntawm daim ntawv thov
- Kev tu vaj tse: tshem tawm cov roj thiab roj (xws li, ntxuav cov khoom siv tshuab).
- Paints thiab inks: Siv raws li diluents los kho viscosity.
- Chemical synthesis: Siv los ua cov tshuaj tiv thaiv nruab nrab lossis extractant.
- Cov khoom siv tshuaj txhua hnub: roj cov kuab tshuaj hauv cov tshuaj pleev ib ce (piv txwv li, tshuaj pleev ib ce).
Qhov zoo thiab ceev faj
- Qhov zoo: Cov kuab tshuaj muaj zog, evaporation sai, tus nqi qis.
- Kev ceev faj:
- Toxicity: Aromatic hydrocarbons xws li benzene ua rau muaj kev pheej hmoo carcinogenic thiab xav tau kev tiv thaiv.
- Flammability: Feem ntau yog cov nplaim taws heev thiab xav tau kev tiv thaiv hluav taws thiab tawg.
- Ib puag ncig cuam tshuam: Qee qhov nyuaj rau degrade thiab yuav tsum tau muab pov tseg raws.
Environmental Alternatives Trend
Nrog ntxiv dag zog rau ib puag ncig cov cai, dej-raws li cov kuab tshuaj thiab bio- cov kuab tshuaj raws li cov kuab tshuaj (xws li limonene) tau maj mam hloov cov tshuaj hydrocarbon cov kuab tshuaj.
