PHTHALIC ACID MONO-2-ETHYLHEXYL ESTER synthesis

4synthesis methods

Yield:-

Reaction Conditions:

at 140;

Steps:


The mono ester was prepared in first step by taking equimolar proportion (0.025 mol) of acid and alcohol (malonic acid and ethanol for DEM, succinic acid and ethanol for DES, phthalic anhydride and 1-butanol for DBP,phthalic anhydride and 2-ethyl 1-hexanol for DOP) were taken in a round bottomed flask and the reaction mixture stirred at ~80°Cfor DEM and DES, ~110°C for DBP and ~140°C for DOP for about10-15 min in absence of any catalyst and solvent. The dicarboxylic acid and anhydride get completely converted to the monoester,so that the acid concentration at this stage is taken as the ini-tial concentration.
