Intangiriro
2,2-dimethyl-1, 3-dioxan-5-imwe ni ifumbire mvaruganda hamwe na formula C6H10O3. Ibikurikira nubusobanuro bwimiterere yabyo, imikoreshereze, imyiteguro namakuru yumutekano:
Kamere:
2,2-Dimethyl-1,3-dioxan-5-imwe ni amazi atagira ibara afite impumuro idasanzwe ya ketone. Ifite ubucucike bwa 0,965 g / mL, ahantu hatetse 156-157 ° C, hamwe na flash ya 60 ° C. Irashobora gushonga mumashanyarazi menshi nka Ethanol, Ethyl acetate na dichloromethane.
Koresha:
2,2-Dimethyl-1,3-dioxan-5-imwe ni interineti ikoreshwa cyane hagati ya synthesis. Irashobora gukoreshwa nka agent ya ketonizing, esterifying agent na condensing agent muri synthesis. Irashobora gukoreshwa muguhuza ibindi bintu kama, nka coatings, resin, amarangi, imiti nubuvuzi bwiza.
Uburyo bwo Gutegura:
Uburyo bwo gutegura bwa 2,2-Dimethyl-1,3-dioxan-5-imwe irashobora kugerwaho na reaction ya Uskberg. By'umwihariko, 1,3-butanediol ikoreshwa na methyl iyode kugirango ikore 2,2-dimethyl -1,3-dioxane. Noneho, 2,2-dimethyl -1,3-dioxane ikorerwa reaction ya okiside imbere ya iyode, kandi ibicuruzwa ni 2,2-Dimethyl-1,3-dioxan-5-imwe.
Amakuru yumutekano:
