Scientists turn beer into fuel
Chemists at the University of Bristol have made the first steps towards making sustainable petrol using beer as a key ingredient.
It is commonly accepted that there is an urgent need for sustainable alternatives to fossil fuels for transportation to replace diesel and petrol.
One of the most widely used sustainable alternatives to petrol world-wide is bioethanol - in the United States gasoline is typically sold as a blend with up to 10 percent ethanol.
It is also know that ethanol is not an ideal replacement for petrol as it has issues such as lower energy density, it mixes too easily with water and can be fairly corrosive to engines.
A much better fuel alternative is butanol but this is difficult to make from sustainable sources.
Scientists from the University of Bristol's School of Chemistry have been working for several years to develop technology that will convert widely-available ethanol into butanol.

Useful Alcohols: Ceresana Analyzes the World Market for Solvents
Are solvents a solution to our waste problem? In any case, they can be used to recover raw materials that are as good as new, even from mixed or contaminated waste: Solvents allow targeted and clean removal of unwanted plastic types, labeling, and impurities. Chemical plastic recycling is an innovative application example for solvents. The potent chemicals can dissolve or dilute other substances without chemically altering them. Not only precision cleaning agents for printed circuit boards and microchips, but also nail polish remover and numerous other everyday products would hardly be possible without isopropyl alcohol, acetone, and more. Ceresana has now analyzed the global market for solvents for the fifth time.

In our initial discussions of butan-2-ol, we used the representation in figure 17.16a to show the tetrahedral geometry of the central carbon atom (the stereocentre); in it, two groups (-CH3 and -OH) are in the plane of the paper, one (-CH2CH3) is coming out of the plane towards us, and one (-H) is behind the plane, away from us.

Abstract Biobutanol is one of the types of biofuels produced using microbial synthesis (acetoneābutanolāethanol fermentation). It is possible to increase the level of accumulation of the target product due to metabolic changes in producer cells under the influence of stress factors. For this purpose, the effect of such stress factors as allopurinol, furfural, zinc, and oxygen, as well as glycerol as a nonspecific substrate on the functioning of Clostridium sp. cells, was studied. It was demonstrated that the butanol concentration was the highest (1.2 g/L) as compared with the control (0.6 g/L) when adding 0.5 g/L of furfural to the culture medium. The use of ZnSO4 at a concentration of 0.001 g/L increased the butanol concentration to 1.1 g/L, and the highest butanol concentration (1.3 g/L) was obtained when using glucose and glycerol as carbon sources in a ratio of 1 : 3. The butanol concentration in the culture medium increased to 0.8 g/L with the addition of 0.025 g/L of allopurinol. The possibility of using the above-mentioned stress factors to increase the accumulation of the target product by influencing the metabolic pathways in microorganism cells is substantiated
1-butanol is expected to register rapid revenue CAGR during the forecast period. The major factors driving the revenue growth for the market are its wide range of applications in artificial flavoring and consumer products such as cosmetics, and its use as an extractant in medicines.
