Table 1: Experimental data of captan water solubility at 15°C:
Table 2: Experimental data of captan water solubility at 25°C
Captan is slightly soluble and is well known to be unstable in water
(refer to hydrolysis studies).
In case of cleaning processes effects on water emissions are expected to
be low. Effective cleaning can only be done by use of organic solvents.
Solubility of captan was determined to be in maximum 3.77 mg/L at 25°C by HPLC detection. Captan is well known to be unstable in water with half-life times of 2.7 h.
Water solubility of captan which was determined by flask method is about
3.77 mg/L at 25°C. Solubility is therefore assessed to be very low
resulting in low emissions in aqueous process steps. Additionally the
half-life time of 4.9 hours indicates low stability either.
