4-Phenoxybutanoic acid Usage And Synthesis

Purification Methods

It has been purified by recrystallisation from pet ether, *C6H6, Et2O/pet ether, EtOH and from H2O. It can be steam distilled or distilled in a good vacuum. [UV: Ramart-Lucas & Hoch Bull Soc Chim Fr [4] 51 824 1932, Dann & Arndt Justus Liebigs Ann Chem 587 38 1954.] The acid chloride has b 154-156o/20mm [Hamford & Adams J Am Chem Soc 57 921 1935], and the amide crystallises from *C6H6 as needles with m 113o. [Beilstein 6 IV 645.]
