Catalytic Conversion of Renewable Resources into Bulk and Fine Chemicals

20-Oct-2016 | Johannes G. de Vries, The Chemical Record, 2016

Abstract Several strategies can be chosen to convert renewable resources into chemicals. In this account, I exemplify the route that starts with so‐called platform chemicals; these are relatively simple chemicals that can be produced in high yield, directly from renewable resources, either via ...

Design of recombinant whole-cell catalysts for double reduction of C[double bond, length as m-dash]C and C[double bond, length as m-dash]O bonds in enals and application in the synthesis of Guerbet alcohols as industrial bulk chemicals for lubricants

16-Sep-2016 | Marc Biermann; Daniel Bakonyi; Werner Hummel; Harald Gröger, Green Chemistry, 2016

Whole-cell catalysts overexpressing two enzymes for a double reduction cascade in which aliphatic α-branched α,β-unsaturated aldehydes are converted into Guerbet alcohols as a highly demanded class of lubricants were constructed and characterized. The reaction conditions were optimized to ...

Cascade Biocatalysis for Sustainable Asymmetric Synthesis: From Biobased l‐Phenylalanine to High‐Value Chiral Chemicals

11-Aug-2016 | Yi Zhou, Shuke Wu, Zhi Li, Angewandte Chemie International Edition, 2016

Abstract Sustainable synthesis of useful and valuable chiral fine chemicals from renewable feedstocks is highly desirable but remains challenging. Reported herein is a designed and engineered set of unique non‐natural biocatalytic cascades to achieve the asymmetric synthesis of chiral epoxide, ...

Thermochemical conversion of lignin for functional materials: A review and future direction

14-Jul-2015 | Wu-Jun Liu; Hong Jiang; Han-qing Yu, Green Chemistry, 2015

Lignin valorization is considered as an important part of the modern biorefinery scheme. The unique structure and composition of lignin may offer many effective routes to produce several bulk chemicals and functional materials. Thermochemical conversion of the lignin to synthesize the value-added ...

New challenges for syngas fermentation: towards production of biopolymers

18-May-2015 | Oliver Drzyzga, Olga Revelles, Gonzalo Durante‐Rodríguez, Eduardo Díaz, José L. García, Auxiliadora Prieto, Journal of Chemical Technology & Biotechnology, 2015

Abstract Organic wastes are a suitable feedstock for the production of value‐added products that have been insufficiently exploited due to their complexity, which challenges their transformation by conventional procedures. Gasification and pyrolysis of organic wastes can reduce this complexity ...

Selective and Controllable Purification of Monomeric Lignin Model Compounds via Aqueous Phase Reforming

08-May-2015 | Malte Otromke; Lara Theiss; Anna Wunsch; Alexander Susdorf; Thomas Aicher, Green Chemistry, 2015

Depolymerization of lignin into its monomeric constituents is a promising way to produce aromatic bulk chemicals from lignocellulosic biomass and lignin waste streams. In order to obtain an industrial product further downstream processing of the monomeric mixture will be needed. Therefore, we ...

ChemInform Abstract: Improved and Scalable Preparation of 6‐Bromo‐4‐chlorothieno[2,3‐d]pyrimidine.

02-Apr-2015 | S. Bugge, E. M. Skjoensfjell, F. B. Willumsen, E. Sundby, B. H. Hoff, ChemInform, 2015

Abstract The title compound (VII), a useful precursor for the synthesis of a library of thienopyrimidine‐based kinase inhibitors, is obtained starting from cheap bulk chemicals in four steps.

Catalytic Routes towards Acrylic Acid, Adipic Acid and [varepsilon]-Caprolactam starting from Biorenewables.

26-Nov-2014 | Rolf Beerthuis; Gadi Rothenberg; Raveendran N Shiju, Green Chemistry, 2014

The majority of bulk chemicals are derived from crude oil, but the move to biorenewable resources is gaining both societal and commercial interest. Reviewing this transition, we first summarise the types of today’s biomass sources and their economical relevance. Then, we assess the biobased ...

A systems engineering perspective on process integration in industrial biotechnology

03-Nov-2014 | Anton A. Kiss, Johan Grievink, Marco Rito‐Palomares, Journal of Chemical Technology & Biotechnology, 2014

Abstract Biotechnology has many applications in health care, agriculture, industrial and environmental uses. By using renewable raw materials, biotechnology contributes to lowering greenhouse gas emissions and moving away from a petro‐based towards a circular sustainable economy. However, ...

Production of Bio-Ethene and Propene: Alternatives for bulk chemicals and polymers

22-Aug-2013 | Thomas Dijckmans; Steven P. Pyl; Ramin Abhari; Marie-Françoise Reyniers; Kevin M. Van Geem; Guy. Marin, Green Chemistry, 2013

There is an increasing trend to use bio-polyethene and bio-polypropene in Europe. However there is at present very limited production capacity available for producing the base chemicals that are used in polymerization processes. Therefore a production route for green ethene, propene and ...
