Organocatalyzed Synthesis of Oleochemical Carbonates from CO2 and Renewables

07-Nov-2016 | Hendrik Büttner, Johannes Steinbauer, Christoph Wulf, Mehmet Dindaroglu, Hans‐Günther Schmalz, Thomas Werner, ChemSusChem, 2016

Abstract Bifunctional phosphorus‐based organocatalysts proved to be highly efficient for the atom‐economic reaction of CO2 and epoxidized oleochemicals. Notably, those products are obtained from CO2 and renewable feedstocks only. Structure–activity relationships have been deduced from a ...

Cooperative catalyst system for the synthesis of oleochemical cyclic carbonates from CO2 and renewables

05-May-2016 | Nils Tenhumberg; Hendrik Büttner; Benjamin Schäffner; Daniela Kruse; Michael Blumenstein; Thomas Werner, Green Chemistry, 2016

Phosphonium salts and various (transition-) metals were studied as catalysts in the synthesis of carbonated oleochemicals from the corresponding epoxides and carbon dioxide. In combination with tetra-n-butylphosphonium bromide molybdenum compounds were identified as highly active co-catalysts for ...

Novel basic ionic liquids from cyclic guanidines and amidines ‐ new catalysts for transesterification of oleochemicals

02-May-2013 | Janusz Nowicki, Marcin Muszyński, Stanisław Gryglewicz, Journal of Chemical Technology & Biotechnology, 2013

Abstract Background Alkylguanidinium and alkylamidinium hydroxides have been developed as new basic ionic liquids what has been done for the first time from cyclic guanidine (TBD) and amidines (DBN, DBU). The method of preparation of [bmim]OH decribed in literature was adopted for the ...

Monomers and polymers from plant oils via click chemistry reactions

21-Mar-2013 | Gerard Lligadas, Juan C. Ronda, Marina Galià, Virginia Cádiz, Journal of Polymer Science Part A: Polymer Chemistry, 2013

As a consequence of the depleting of fossil reserves and environmental issues, today, plant oils and fatty acids derived therefrom have a respectable status within the polymer chemistry community. However, maximizing the benefits of these renewable feedstocks requires the utilization of ...

Yellow‐pigmented Cupriavidus sp., a novel bacterium capable of utilizing glycerine pitch for the sustainable production of P(3HB‐co‐4HB)

26-Sep-2012 | Hema Ramachandran, A.A. Amirul, Journal of Chemical Technology & Biotechnology, 2012

Abstract Background Development of bacterial strains that can utilize cheap and renewable carbon substrate will make the prices of poly(3‐hydroxybutyrate‐co‐4‐hydroxybutyrate) [P(3HB‐co‐4HB)] competitive with synthetic plastics. Disposal of glycerine pitch, which is a scheduled waste from ...

A Highly Efficient Olefin Metathesis Process for the Synthesis of Terminal Alkenes from Fatty Acid Esters

21-Jun-2012 | Andrew Nickel, Thay Ung, Garik Mkrtumyan, Jane Uy, Choon Woo Lee, Diana Stoianova, Jason Papazian, Wen-Hao Wei, Alla ..., Topics in Catalysis, 2012

Recently, considerable attention has been focused on the use of olefin metathesis to convert oleochemicals into value-added products such as the bifunctional molecule methyl 9-decenoate, but the implementation of this process has been hampered by low ethenolysis efficiencies. We report herein the ...

Industrial development and applications of plant oils and their biobased oleochemicals

23-Apr-2012 | Jumat Salimon, Nadia Salih, Emad Yousif, Arabian Journal of Chemistry, 2012

In the concepts for new products, performance, product safety, and product economy criteria are equally important. They are taken into account already when the raw materials base for a new industrial product development is defined. Here, renewable resources gain-again after the earlier “green ...

Development of Pharmaceuticals from Indonesian Natural Resources, Genetically Engineered Microbes and Diversification of Palm Oil Products

06-Dec-2011 | Suharto, Ignatius; Kardono, Leonardus B.S., Natural Product Chemistry, 2011

Abstract: The objective of this paper is to give an overview on natural resources in terms of renewable resources as well as non-renewable resources for the development of new pharmaceuticals, chemical and food products, the roles of microbial cells in solid substrate fermentation and ...

Secrets of palm oil biosynthesis revealed [Commentary]

26-Jul-2011 | Voelker, T., Proceedings of the National Academy of Sciences current issue, 2011

Globally, vegetable oils are harvested from a handful of oil crops at an annual rate exceeding 100 million tons (1). Most oils are used for human or animal consumption, although a minor fraction is derivatized to oleochemicals. More recently, an increasing amount of vegetable oil is being ...
