Chemconserve
“Market introduction of products and technologies for the circular economy”
About Us
Chemconserve, originally established by the late Dim Kesber, is an innovative company dedicated to the re-use of critical raw materials. The portfolio of completed projects since 1986 reflects how we have applied technology to re-use materials and contributed to the circular economy.
Our current business activities consist of the trade of TriphenylPhosphine (TPPO) by
Chemconserve and the creation and market introduction of hydrophobicity in wood flour for application in Wood Polymer Composites through our subsidiary company CCWood. More information on the latter can be found on the website ccwood.com. The trade of TPPO has been one of the company activities for more than 20 years. Our product has been re-used in various applications in chemical production as a result of the exceptionally high levels of purity, and absence of TPP or other organics.
The management has been partially renewed in March 2014 to continue the supply of high-quality TPPO and find innovative technical applications for specialty chemicals.

Product Analysis
Product analysis
Analysis by the Faculty of Sciences of the Vrije Universiteit Amsterdam, Department of Chemistry and Pharmaceutical Sciences, Division of Organic Chemistry, Dr. Chris Slootweg: “Shown is a GC/MS analysis of the sample, indicating 99.98% purity on gas chromatographic basis (topmost graph). Specifically, no presence of Triphenylphosphine could be detected at its characteristic GC retention time of 9.69 minutes (middle graph, insert of topmost graph). The analytic methodology used allows us to detect triphenylphosphine quantities down to 0.08% (not shown). The mass spectroscopy results of the predominant chemical component in the sample confirm that the component comprising 99.98 % wt. is indeed TPPO (bottom graph).”
