Abstract

Maize starch was reacted with butyl acrylate (BuA) in presence of NaOH as a catalyst. The reaction products consists essentially of mixed starch ethers namely starch butyl acrylate i.e. starch bearing BuA moieties and carboxyethyl starch. Hence, they were monitored for ether % to bring into focus the extent of reaction of starch with BuA to yield starch butyl acrylate and; for carboxyl content expressed as DS to find out to what extent was the starch butyl converted to carboxyethyl starch. Dependence of the extent of the acrylate etherification reaction expressed as ether % and DS on conditions of the reaction was studied. Results obtained indicate that the extent of the reaction attains the highest values at NaOH and BuA concentrations of I mole/I mole starch and 60 %, ows, respectively, temperature of 55° C and reaction time of 20 hrs. The reaction occurs easily using water/solvent ratio 4m1/4m1.. A tentative mechanism for the reactions involved is also reported.
