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.
