Mawu Oyamba
2,2-dimethyl-1, 3-dioxan-5-imodzi ndi organic pawiri ndi chilinganizo C6H10O3. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
2,2-Dimethyl-1,3-dioxan-5-imodzi ndi madzi opanda mtundu okhala ndi fungo lapadera la ketone. Ili ndi kachulukidwe ka 0.965 g/mL, kuwira kwa 156-157 ° C, ndi kung'anima kwa 60 ° C. Amasungunuka muzinthu zambiri zosungunulira organic monga ethanol, ethyl acetate ndi dichloromethane.
Gwiritsani ntchito:
2,2-Dimethyl-1,3-dioxan-5-imodzi ndi organic synthesis wapakatikati. Itha kugwiritsidwa ntchito ngati ketonizing wothandizira, esterifying wothandizira ndi condensing wothandizira mu synthesis. Itha kugwiritsidwa ntchito popanga zinthu zina zakuthupi, monga zokutira, utomoni, utoto, mankhwala ndi mankhwala abwino.
Njira Yokonzekera:
Njira yokonzekera ya 2,2-Dimethyl-1,3-dioxan-5-imodzi ikhoza kukwaniritsidwa ndi Uskberg oxidation reaction. Mwachindunji, 1,3-butanediol imachitidwa ndi methyl iodide kupanga 2,2-dimethyl -1,3-dioxane. Kenako, 2,2-dimethyl -1,3-dioxane imakhudzidwa ndi okosijeni pamaso pa ayodini, ndipo mankhwalawa ndi 2,2-Dimethyl-1,3-dioxan-5-imodzi.
Zambiri Zachitetezo:
