Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Using the AOPWIN QSAR model, the photochemical degradation rate of Potassiumisobutyl xanthate in the atmosphere is 14.1324 E-12 cm3/molecule-sec, with a resultant predicted half live of 9.082 Hrs (0.757 Days (12-hr day; 1.5E6 OH/cm3).
If released to air, a vapor pressure of 1.26E-009 mm Hg at 25 deg C (1.26E-009 mm Hg is equivalent to 1.68E-007 Pa ) indicates that Potassium isobutyl xanthate will exist solely as a vapor in the atmosphere. Vapor-phase Potassium isobutyl xanthate will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 0.757 days, calculated from its rate constant of 14.1324 E-12 cm3/molecule-sec at 25 deg.
Xanthates do not contain chromophores that absorb at wavelengths >290 nm and therefore Potassium isobutyl xanthate is not expected to be susceptible to direct photolysis by sunlight.
Key value for chemical safety assessment
- Half-life in air:
- 0.757 d
- Degradation rate constant with OH radicals:
- 0 cm³ molecule-1 s-1

OVERALL OH Rate Constant = 14.1324 E-12 cm3/molecule-sec
HALF-LIFE = 0.757 Days (12-hr day; 1.5E6 OH/cm3)
HALF-LIFE = 9.082 Hrs
