Abstract
Using optical L- Alanine as the starting material,R-( +)- 2-( 4- hydroxyphenoxy)- propionic acid was synthesized via chlorination,etherification and hydrolysis reaction,and the configuration was reversed in etherification reaction. The conditional test of reaction temperature and time,molar ratio to reactants were processed and a best technical condition was explored. The yield was up to 71. 1% and the product structure was characterized by1 H NMR and MS spectrum. The product purity was characterized by HPLC. This synthesis process features ready availability of raw materials,mild operating regime,high product yield,and insignificant environmental pollution,which was suitable for industrialized production.
