Description
Предлагаемый- метод получени 4-фенил-4-метил-1,3-дноксана заключаетс в том, что а-метплстирол обрабатывают формальдегидом (водный раствор) в присутствии сол ной кислоты на кип щей вод ной бане. Образовавшийс диоксан промывают водой, сушат над CaClj и перегон ют под вакуумом .The proposed method for the preparation of 4-phenyl-4-methyl-1,3-donoxane is that a-metpstyrene is treated with formaldehyde (aqueous solution) in the presence of hydrochloric acid in a boiling water bath. The dioxane formed is washed with water, dried over CaClI and distilled under vacuum.
4-фенил-1,3 диоксан может быть использован в качестве сырь дл получени фенольно-дноксановых смол, так как в кислой среде он распадаетс на 1-фенилЗ-метпленгликоль-1 ,3 п формальдегид , реагируюш;ие с фенолами.4-phenyl-1,3 dioxane can be used as a raw material for the production of phenol-DNOX resins, since it decomposes into 1-phenyl 3-metphenylene-1, 3 n formaldehyde in an acidic medium, reacts with phenols.
Пример, з-метилстирол ... -1 .моль формальдегид (ЗТ /с-ный водный раствор) . . -2 .мол сол на кислота (уд. вес 1,19) . . -20 млExample, s-methylstyrene ... -1. Mol formaldehyde (ST / s-ny aqueous solution). . -2 mol hydrochloric acid (sp. Weight 1,19). . -20 ml
Смесь нагревают на кип гцей вод ной бане в течение п ти часов , затем полученный диоксан промывают, сушат и перегон ют под вакуумом.The mixture is heated in a boiling water bath for five hours, then the resulting dioxane is washed, dried and distilled under vacuum.
Выход диоксана составл ет 97 -99-о от георстического значени .The dioxane yield is 97-99% of the georstonic value.
