Several degradation products are detected: Isobutyric acid (isoBAcid), isopropylalcohol (IPA), propene, and acetone. The amounts of these compounds and the rest peroxide (Trigonox 187, abbreviated as Tx-187 in the spectrum) were calculated using acetic acid (peak) as internal standard.
Applicant's summary and conclusion
- Conclusions:
- For the degradation of Diisobutryl peroxide in water it can be concluded that:
- Diisobutryl peroxide decomposes completely in water after 60 minutes at 27°C (room temperature).
- The decomposition products observed are: Isobutyric acid (IBA), Isopropanol, propene and acetone.
- The main decomposition/hydrolysis product found is Isobutyric acid.
- Propene is also likely to be one of the main decomposition products but the exact amount can not be determined due to its high volatile nature. - Executive summary:
The test material concerned decomposes to a mixture of decomposition products that were identified and quantified during this experiment. The study was a non standard research based investigation. No guideline was followed and no GLP accreditation was given. Due to the specialist and complex nature of the measurments these results are considered to have limitations but are considered reliable with the resrictions mentioned.
