| Txheej txheem cej luam | p-hydroxyacetophenone, vim hais tias nws cov molecule muaj hydroxyl thiab ketone pawg ntawm lub nplhaib benzene, yog li ntawd, nws yog feem ntau siv los ua ib qho nruab nrab hauv cov organic synthesis kom hnov mob nrog lwm cov tebchaw los tsim ntau yam tseem ceeb. Feem ntau siv rau kev sib txuas ntawm cov tshuaj intermediates (α-bromo-p-hydroxyacetophenone, tshuaj choleretic, tshuaj tua kab mob thiab lwm yam tshuaj), Lwm yam (steev, pub, thiab lwm yam.; tshuaj tua kab, dyes, kua siv lead ua kua, thiab lwm yam). |
| Daim ntawv thov | p-hydroxyacetophenone yog dawb koob zoo li siv lead ua nyob rau hauv chav tsev kub, ib txwm tshwm sim nyob rau hauv stems thiab nplooj ntawm Artemisia scoparia, nyob rau hauv cov hauv paus hniav ntawm cov nroj tsuag xws li ginseng me nyuam Vine. Nws tuaj yeem siv rau hauv kev tsim cov tshuaj choleretic thiab lwm cov ntaub ntawv raw rau cov organic synthesis. |
