3-tertiary butyl-4-hydroxyphenylpropionic acid preparation method

The invention relates to a 3-tertiary butyl-4-hydroxyphenylpropionic acid preparation method. The 3-tertiary butyl-4-hydroxyphenylpropionic acid preparation method solves the problems of poor reaction selectivity, low yield and serious environmental pollution in the existing preparation process of 3-tertiary butyl-4-hydroxyphenylpropionic acid. The 3-tertiary butyl-4-hydroxyphenylpropionic acid preparation method comprises the following steps: step one, carrying out dealkylation reaction; step two, carrying out selective hydrolyzation, extracting to obtain a water phase and an organic phase, and recycling a solvent from the organic phase to obtain an organic phase concentrate; step three, separating and purifying to obtain crude 3-tertiary butyl-4-hydroxyphenylpropionic acid; recrystallizing the 3-tertiary butyl-4-hydroxyphenylpropionic acid to obtain the pure 3-tertiary butyl-4-hydroxyphenylpropionic acid, and recycling the solvent from a recrystallized mother solution to obtain mother solution recovered materials for later use; and step four, using the organic phase concentrate obtained in the step two as dealkylation reaction raw materials, recycling and reacting. The products prepared by the method are white crystals and have the purity of up to above 98.5%; the total yield of the products reaches above 90%; and the preparation method is used for preparing the 3-tertiary butyl-4-hydroxyphenylpropionic acid.
