The method comprises the following steps: (1), adding hydroquinone into a sodium hydroxide solution containingan organic solvent in batches, and performing reaction under in N2 atmosphere, so as to obtain p-hydroxy sodium phenate turbid liquid; (2), dissolving S-(-)-2-chloropropionic acid in an organic solvent, and slowly adding Na2CO3 solid in an ice-water bath condition to perform reaction, so as to obtain an S-(-)-2-sodium chloropropionic acid solution; (3), slowly dropwise adding the solution in the step (2) into the turbid liquid in the step (1), and performing reduced pressure distillation, dissolution and acidification, extraction and reduced pressure distillation on obtained reaction liquid, so as to obtain white solid, namely the R-(+)-2-(4-hydroxyphenoxy) propionic acid. The synthesis method has the advantages of simple synthesis route, mild reaction condition, high product yield, high product optical purity ee value, high recovery rate of hydroquinone, less produced three wastes and low energy consumption.

PROCESS FOR THE RECOVERY OF PHENOL AND BIPHENOLS

A process is described for the recovery of phenol and biphenols from their homogeneous mixtures containing benzene, sulfolane and water, which is based on the use of an alkaline solution and benzene for the separation of biphenols from sulfolane, after removing the benzene, H2O and phenol contained in the reaction effluent. The process allows the recovery of phenol and biphenol by-products dissolved in sulfolane, directly obtaining the purified solvent containing the benzene necessary for the feeding to the reactor for the direct oxidation of benzene, as well as the biphenols dissolved in water and pure phenol.
