A guideline study of abiotic degradation (Groult R, 2002) has shown no degradation in the preliminary test. This consisted of studying the stability of a solution of the substance at 50 degreeC for 5 days in de-aerated test media at pH 4, 7 and 9. The result suggests that the hydrolytic half-life of 2,2 -bis(chloromethyl)trimethylene bis[bis(2-chloroethyl)phophate] under ambient conditions in the environment is likely to be greater than one year. The study does not test the susceptibility of the substance to abiotic oxidation (i.e. by oxygen). However there are no structural features which would suggest that oxidation is possible. It is very unlikely that the rate of hydrolysis at environmentally-relevant pH values is fast enough to have any influence on predicted environmental concentrations.
