тель) содержит 1 % платины. Через реактор с объемной скоростью 1 л/час пропускают смесь, котора состоит из анилина и ацетона в мольном соотношении 1:4 и из 5% третбутилового спирта. Температура реакции 1бО°С, давление водорода в реакторе 50 ати. Получают 5000 г продукта, который после обезвоживани раздел ют в колонне на фракцию , кип щую до 100°С, и фракцию, кип щую выще 100°С.Tel) contains 1% platinum. A mixture with aniline and acetone in a molar ratio of 1: 4 and from 5% tert-butyl alcohol is passed through the reactor with a flow rate of 1 l / h. The reaction temperature 1bO ° C, the hydrogen pressure in the reactor 50 MPa. 5000 g of product are obtained, which, after dehydration, are separated in the column into a fraction boiling up to 100 ° C and a fraction boiling above 100 ° C.
