Mawu Oyamba

(S) -3-hydroxy-γ-butyrolactone ndi organic pawiri. Ndi madzi opanda mtundu okhala ndi kukoma kokoma, zipatso.

Pali njira zingapo zopangira (S) -3-hydroxy-γ-butyrolactone, zomwe nthawi zambiri zimapezeka ndi catalytic hydrogenation. Njira yeniyeni ndiyo kuchitapo kanthu koyenera kwa γ-butyrolactone ndi chothandizira (monga alloy-lead alloy) pa kutentha koyenera ndi kupanikizika, ndipo pambuyo pa catalytic hydrogenation, (S) -3-hydroxy-γ-butyrolactone imapezeka.

Zambiri Zachitetezo: (S) -3-hydroxy-γ-butyrolactone ili ndi kawopsedwe kakang'ono pakagwiritsidwe ntchito wamba ndipo si mankhwala owopsa. Chisamaliro chiyenera kutengedwa kuti musakhudze khungu, maso, ndi kupuma kwapanthawi yogwiritsira ntchito. Mukakhudzana mwangozi, muzimutsuka ndi madzi ndikupita kuchipatala nthawi yake. Pawiri ayenera kukhala kutali poyaka ndi kutentha kwambiri malo, ndipo kupewa kukhudzana ndi okosijeni ndi zidulo. Kuphatikiza apo, iyenera kugwiritsidwa ntchito motsatira njira zoyendetsera bwino komanso njira zoyendetsera ntchito zotetezeka.
