Calculation with HYDROWIN v2.00 (EPIWIN software by US-EPA):Total kb for pH > 8 and 25 °C = 1.145E-02 L/mol-secKb Half-life at pH 8 = 1.918 yearsKb Half-life at pH 7 = 19.183 years
The estimation of hydrolysis rate constants
of tributyl citrate was done using HYDROWIN program (v 2.00) made
available by the U.S. EPA. This
program requires just the input of the chemical structure of the desired
compound by SMILES notation and estimates the hydrolysis rate constants
for specific organic classes and, furthermore, hydrolysis half-lifes
under typical environmental conditions. The prediction for tributyl
citrate indicated that esters were detected as hydrolysable substance
class. The total base-catalysed rate constant at pH > 8 and 25 °C has
been calculated to be 1.145E-02 L/mol-sec, the half-lives are predicted
to be 1.918 years at pH 8 and 19.183 years at pH 7, so the hydrolysis
takes place very slowly.
