Isingeniso
I-2,2-dimethyl-1, i-3-dioxan-5-one iyinhlanganisela ye-organic enefomula ethi C6H10O3. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
I-2,2-Dimethyl-1,3-dioxan-5-one iwuketshezi olungenambala olunephunga elikhethekile le-ketone. Inokuminyana okungu-0.965 g/mL, indawo yokubilisa engu-156-157°C, kanye nephuzu elikhanyayo elingu-60°C. Incibilika kuzincibilikisi eziningi eziphilayo njenge-ethanol, i-ethyl acetate ne-dichloromethane.
Sebenzisa:
I-2,2-Dimethyl-1,3-dioxan-5-one iyinhlanganisela esetshenziswa kakhulu ye-organic synthesis. Ingasetshenziswa njenge-ejenti ye-ketonizing, i-esterifying ejenti kanye ne-ejenti yokujiya ekuhlanganiseni. Ingasetshenziswa ekuhlanganisweni kwamanye ama-organic compounds, njengama-coatings, ama-resin, odayi, imithi kanye namakhemikhali amahle.
Indlela Yokulungiselela:
Indlela yokulungiselela ye-2,2-Dimethyl-1,3-dioxan-5-one ingafinyelelwa ngokusabela kwe-oxidation yase-Uskberg. Ngokuqondile, i-1,3-butanediol isabela nge-methyl iodide ukukhiqiza i-2,2-dimethyl -1,3-dioxane. Khona-ke, i-2,2-dimethyl -1,3-dioxane ibhekene nokusabela kwe-oxidation phambi kwe-iodine, futhi umkhiqizo u-2,2-Dimethyl-1,3-dioxan-5-one.
Ulwazi Lokuphepha:
