M. Sc. Johanna Vondran

Development of innovative conversion processes: oxidation reactions of renewables using „green“ oxidants

Curriculum Vitae:

During her bachelor studies (2012-2015), Johanna Vondran focused on technical chemistry and finished her thesis on the topic of the “palladium catalyzed aminocarbonylation of unsaturated substrates through formamides” under supervision of Prof. Behr at TU Dortmund. She received the “Deutschlandstipendium” first by Sparkasse Dortmund (2014/15), then by BASF (2015-2017). In advanced stage of her master studies, she went abroad to absolve an internship on flow chemical processes at the University of Melbourne, Australia, in the group of Dr. Polyzos. She graduated in the group of Prof. Vogt in September 2017 at TU Dortmund on the topic of the “palladium-catalyzed carbonylative aminetelomerization of 1,3-butadiene with secondary amines to linear unsaturated pelargonic amides”. Afterwards, she gained industrial work experience through an internship at Covestro in Leverkusen working on UV-curable prepregs. Since April 2018 she has worked as a research associate at the laboratory of industrial chemistry supported by a Ph.D. scholarship by “Fonds der chemischen Industrie”.

Research Topic:

Regarding the vast array of oxidation reactions, there is still a high potential of enhancement towards sustainability. One important industrial application of oxidations is the ozonolysis of oleic acid, which comes along with the need for highly toxic, explosive and expensive ozone. An alternative synthesis route to the target molecules mono methyl azelate and pelargonic acid, which are used in the synthesis of several lubricants, plasticizers or polymers, is the homogeneously catalyzed oxidative cleavage of oleic acid.

Due to the use of hydrogen peroxide as “green” oxidant instead of other frequently used oxidants (sodium periodate, potassium permanganate) it is an environmentally friendly reaction, since the only inevitable by-product is water. Homogeneous transition metal catalysis allows for a highly controllable “degree of oxidation”. Nevertheless, an efficient recycling strategy is of need to meet the requirements towards sustainability and be able to compete on industrial scale.
