Sustainable Raw Material Base and Green Chemistry
New Raw Materials Create a New Set of Challenges for Green Chemistry
New Synthesis Techniques Required For Renewables
Since renewables and CO2 both contain too much oxygen in relation to the target end products, reduction has to take place during the conversion process.
Reduction processes and the use of hydrogen / energy are two inherent disadvantages. That is only the case however if the target compounds are the same as in petro-based chemistry.
The development of new intermediates which contain more oxygen can be an attractive alternative. Platform chemicals such as diamines, diols and dicarbonic acids for the preparation of polyester and polyamide are attracting an increasing level of interest.
Conversion to syngas is the other alternative, and it applies to renewables such as wood and straw as well as coal and methane. From this perspective, syngas is a universally accessible raw material and the task now is to develop a very broad spectrum of applications. Besides the familiar processes for producing hydrocarbons and methanol, there is a need to develop efficient techniques for a number of other intermediates such as alcohols and esters.
