Известен способ получени указанных соединений путем переэтерификации метилметакрилата соответствующим 4-метилолдиоксоланом . Однако известный способ требует дл своего осуществлени наличи соответствующих 2,2-производных 4-метилолдиоксолана, синтез которых представл ет собой сложную задачу. С целью изыскани легкодоступного сырь и упрощени Процесса предложен способ получени акриловых и метакриловых эфиров 2,2-замещенного 4-метилолдиоксолана путем взаимодействи глицидилового эфира акриловой ИЛИ метакриловой кислоты с избытком соответствующих кетонов в присутствии кислых катализаторов. В качестве катализаторов можно примен ть как протонные кислоты (например, серна или фосфорна ), так и апротонные кислоты (кислоты Льюиса), такие ка.к ВРз, его эфираты, SnCU, А1С1з, TiCU и т. п. Процесс можно цроводить в широком интервале температур в зависимости от типа примен емого катализатора. В качестве кетонов можно использовать ацетон, метилэтилкетон , диэтилкетон, циклогексанон и т. п.A known method for producing these compounds by transesterification of methyl methacrylate with the corresponding 4-methyloldioxolane. However, the known method requires for its implementation the presence of the corresponding 2,2-derivatives of 4-methyloldioxolane, the synthesis of which is a complex task. In order to find a readily available raw material and simplify the Process, a method has been proposed for the preparation of acrylic and methacrylic esters of 2,2-substituted 4-methyloldioxolane by reacting acrylic acid OR methacrylic acid glycidyl ester with an excess of corresponding ketones in the presence of acid catalysts. The catalysts can be used as protic acids (for example, sulfuric or phosphoric) and aprotic acids (Lewis acids), such as VRZ, its ethers, SnCU, A1Cl3, TiCU, etc. The process can be carried out in a wide temperature range depending on the type of catalyst used. As ketones, acetone, methyl ethyl ketone, diethyl ketone, cyclohexanone, etc. can be used.
Акрилаты и метакрилаты 2,2-замещенного 4-метилолдиоксолана представл ют интерес как цромежуточные соединени дл последующих превращений (например, в глицериновые эфиры), а также дл получени соответствующих полимеров из них.Acrylates and methacrylates of 2,2-substituted 4-methyloldioxolane are of interest as intermediates for subsequent transformations (for example, into glycerol esters), as well as for the preparation of the corresponding polymers from them.
Пример. В 500 мл ацетона раствор ют 50 г глицидилметакрилата и в раствор добавл ют 0,5 мл метилэфирата трехфтористого бора при комнатной температуре. Конец реакции определ ют по отрицательному качественному анализу на эпоксидные группы (около 2 час). После отгонки избытка ацетона продукт перегон ют в присутствии ингибитора- р-.фенилнафтиламина. Т. кип. метакрилатаExample. 50 g of glycidyl methacrylate is dissolved in 500 ml of acetone and 0.5 ml of boron trifluoride methylate are added to the solution at room temperature. The end of the reaction is determined by a negative qualitative analysis for epoxy groups (about 2 hours). After distilling off the excess acetone, the product is distilled in the presence of the inhibitor p-phenylnaphtylamine. T. Kip. methacrylate
