Способ синтеза алкидных смол, включающий двухстадийный способ, используемый при работе с растительным маслами, когда на первой стадии производится переэтерификация растительного масла пентаэритритом, а на второй стадии полученный продукт конденсируется с фталевым и малеиновым ангидридами при температуре 240-250°С, отличающийся тем, что пентаэритрит, фталевый и малеиновый ангидриды перед загрузкой в реактор расплавляют, подогревают до температуры 200-210°С и в виде расплава загружают в реактор в глубину реакционной массы, нагретой до температуры 220-230°С, что позволяет не снижать температуру реакционной массы во время загрузки, не останавливать процесс для загрузки, проводить загрузку по ходу реакции и за счет этого сократить время протекания процесса на 25-30%, сэкономить энергоресурсы и повысить экономическую эффективность процесса синтеза алкидных смол.A method for the synthesis of alkyd resins, including a two-stage method used when working with vegetable oils, when in the first stage the transesterification of vegetable oil with pentaerythritol is performed, and in the second stage the resulting product is condensed with phthalic and maleic anhydrides at a temperature of 240-250 ° C, characterized in that pentaerythritol, phthalic and maleic anhydrides are melted before being loaded into the reactor, heated to a temperature of 200-210 ° C and, in the form of a melt, loaded into the reactor deep into the reaction mass heated to a temperature of 220-230 ° C, which makes it possible not to reduce the temperature of the reaction mass during loading, do not stop the process for loading, carry out loading during the reaction and thereby reduce the process time by 25-30%, save energy and increase the economic efficiency of the alkyd resin synthesis process.
