- Executive summary:
Phototransformation of DPG (1,3 -diphenylguanidine) was estimated with Programme V.1.89. Syracuse Corp. This method is described in W.M.Meylan and P.H.Howard, Chemosphere, Vol.26, N°12,pp2293-2299, 1993.
Rate constant (for indirect photolysis): = 0.000000000085 cm³/(molecule*sec)
Degradation in % (for indirect photolysis): = 50 after 2.3 hour(s).
Nevertheless, not enough information is given in order to challenge the validity of this estimation.
