- •
Kinetic model of crystal growth of boehmite until 10 min was developed.
- •
Observed growth rate is considered to be surface reaction limited.
- •
Growth rate increased with increasing octanoic acid concentration.
- •
Variation of pH cannot explain rate increase by octanoic acid.
- •
Possibility of crystal growth enhancement by intermediate inferred.
