Dimedone Siv thiab Synthesis
Chemical Properties khov kho
Siv Ib feem ntawm cov tswv yim furannulation rau cov synthesis ntawm ib txwm tshwm sim fused 3-methylfurans.1
Siv Ib tug mentha compound uas qhia txog cov tshuaj tua kab mob tiv thaiv kab mob hauv kev lag luam khoom noj xws li E.coli thiab P.aeruginosa thiab cov kab mob ntawm cov poov xab.
Siv Siv nyob rau hauv lub synthesis ntawm fused 3-methylfurans ntawm furannulation.
Siv Reagent siv nyob rau hauv synthesis ntawm fused 3-methylfuransDimedone yog siv nyob rau hauv cov organic chemistry los txheeb xyuas cov muaj aldehyde pawg. Nws kuj yog siv los ua ib qho catalyst hauv kev tsim cov kev hloov pauv-hlau complexes. Tsis tas li ntawd, nws tseem ua haujlwm hauv colorimetry, crystallography, luminescence thiab spectrophotometric tsom xam. Ntxiv rau qhov no, nws yog siv rau hauv cov synthesis ntawm ib txwm tshwm sim fused 3-methylfurans.

Kev piav qhia dav dav 5,5-dimethyl-1,3-cyclohexanedione (Dimedone) yog ib qho rhiab heev thiab tshwj xeeb reagent siv rau kev txiav txim siab ntawm aldehydes. Nws yog qhov muaj txiaj ntsig zoo vim nws yog ib puag ncig tus phooj ywg, muab cov txiaj ntsig siab thiab yog cov txheej txheem ua haujlwm yooj yim.
Txoj Kev Purification Crystallize dimedone los ntawm acetone (ca 8mL / g), dej los yog aqueous EtOH. Qhuav nws hauv huab cua. [Schneider & Todd Org Synth Coll Vol II 200 1943, Beilstein 7 H 559, 7 IV 1999.]
