Abstract

Способ получения 2,2,6-тетраметилолциклогексанола конденсацией циклогексанона и формальдегида в водной среде в присутствии гидроксида кальция в качестве катализатора с последующей нейтрализацией реакционной массы и выделением целевого продукта, отличающийся тем, что, с целью увеличения выхода целевого продукта, циклогексанон вводят в водный раствор формальдегида в смеси с суспензией гидроксида кальция порционно, сначала 35-45 мас.% от общего количества приготовленной смеси и затем по истечении 3-5 мин после загрузки - остальное количество смеси.A method of obtaining 2,2,6-tetramethylolcyclohexanol by condensation of cyclohexanone and formaldehyde in an aqueous medium in the presence of calcium hydroxide as a catalyst, followed by neutralization of the reaction mass and isolation of the target product, characterized in that, in order to increase the yield of the target product, cyclohexanone is introduced into the aqueous solution formaldehyde mixed with a suspension of calcium hydroxide in portions, first 35-45 wt.% of the total amount of the prepared mixture and then after 3-5 minutes after loading - the rest mixes.
