Reaction Conditions:

with SO₄^2-/ TiO₂solid super acid catalyst at 80;Large scale;

Steps:

2.3 3) Preparation of crystal rose
2.21 kg of trichloromethylbenzyl alcohol obtained in the step (2) and 0.72 kg of glacial acetic acid are fed to a reaction rectification column equipped with a solid superacid catalyst of SO₄^2-/TiO₂ for esterification. The feed position is at the upper end of the packing of the reaction rectification column, After the esterification reaction at 80 °C, the crude crystal rose is continuously recovered from the tower kettle; Then flash continuously for 2 minutes at a temperature of 180 °C. Obtaining 99.5wt% purity of the product, 2.23kg of crystalline rose product with chromaticity < 5, The recovered aqueous solution of isooctyl alcohol is recycled to the extraction section for recycling.
