Taw qhia

(S)-3-hydroxy-γ-butyrolactone yog cov organic compound. Nws yog cov kua uas tsis muaj xim nrog lub qab zib, fruity saj.

Muaj ntau txoj hauv kev rau kev npaj ntawm (S)-3-hydroxy-γ-butyrolactone, uas feem ntau tau txais los ntawm catalytic hydrogenation. Txoj kev tshwj xeeb yog ua kom muaj qhov tsim nyog ntawm γ-butyrolactone nrog lub catalyst (xws li tooj liab-lead alloy) ntawm qhov tsim nyog kub thiab siab, thiab tom qab catalytic hydrogenation, (S)-3-hydroxy-γ-butyrolactone tau txais.

Cov ntaub ntawv kev nyab xeeb: (S)-3-hydroxy-γ-butyrolactone muaj toxicity tsawg raws li kev siv dav dav thiab tsis yog tshuaj lom neeg. Yuav tsum tau saib xyuas kom tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab ua pa thaum siv. Thaum muaj kev sib cuag tsis raug, yaug nrog dej thiab nrhiav kev kho mob raws sijhawm. Lub compound yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab kub ib puag ncig, thiab tsis txhob sib cuag nrog oxidants thiab acids. Tsis tas li ntawd, nws yuav tsum tau siv raws li cov txheej txheem ua haujlwm kom raug thiab kev ntsuas kev nyab xeeb.
