Welcome to the Institute for Chemical Technology of Organic Materials!

New Coverpaper !!

As highlighted before our colleague Lukas Göpperl published a paper with the title `Impact of Polymerization Process Parameters on Improved Comonomer Incorporation Behavior in Ziegler-Natta Catalysis, opens an external URL in a new window´ in the Journal of Macro-Molecular Reaction Engineering. Now this paper was chosen to grace the cover of this journal.


"Ziegler-Natta based co-polymerization processes generally give rise to a non-uniform incorporation distribution of the comonomer. Lowering the titanation temperature during catalyst synthesis can help to counteract this effect. Using these changes in the catalyst synthesis route and by applying carefully selected polymerization conditions, it can be shown that a more uniform incorporation distribution of the comonomer can be achieved."


Congratulations Lukas !

New Paper !!!

Our colleagues Raphaela Süss, Lukas Zeilerbauer,  and Christian Paulik published a new article with the title `Homogeneously catalyzed depolymerization of lignin
from organosolv medium: Characterization, optimization, and minimization of coke formation´ in the Canadian Journal Of Chemical Engineering (DOI: 10.1002/cjce.24055, Accepted: 18 December 2020).

Congratulations !


This study focused on maximizing yields of oligomeric and monomeric products while minimizing coke formation in the depolymerization of lignin from an organosolv medium. A design of experiments (DoE) with temperature, time, and ethanol-water ratio as factors was established and tested. Optimized reaction conditions were found at 185.4C with 7.5 wt% sodium hydroxide as catalyst, an ethanol-water ratio of 48.6% (v/v), and a residence time of
30 minutes. With these optimized parameters, maximum monomer and oligomer yields of 9.4 wt% and 86.2 wt% and minimized coke formation of 0.5 wt% were achieved. The oligomeric and monomeric products were characterized by GPC, GC-MS, and OH-group determination (Folin-Ciocalteu).

Current research in the CTO group at the Johannes Kepler University Linz focuses on a wide range of organic synthesis of industrial relevance. Especially complex macromolecular architectures with selected functionality and composition via radical and coordination polymerization protocols are of interest. Other points of interest are additive chemistry, renewable resources and process safety. Our research interests are mainly at the interface of organic and polymer chemistry, with particular focus on industrial applications.

Green Labs Austria

Global warming represents one of the biggest threats to the well-being of mankind. Paradoxically, while scientific research is instrumental for solving the imminent climate crisis, our activities contribute significantly to anthropogenic climate change.

Green Labs Austria aims to connect laboratories in Austria that share the vision of a more sustainable research. We want to change the status quo of resource management and offer guidelines for a transition to more environmentally aware research practices. We hope to achieve this by collaborating with groups and institutions from various disciplines.

Specifically, we want to reform how labs and scientists think about energy consumption, plastic consumption, recycling and traveling
