Spinning chemicals for faster reactions

Cardiff University scientists have devised a new way of making reactions up to 70 times faster by using state-of-the-art equipment to spin chemicals around. They found that efficient mixing within a chemical reaction could be achieved by spinning chemicals and catalysts around in a small tube, causing the reactions to happen much quicker. The new findings could have a profound influence on the way that chemicals are made in a wide variety of industries, from drug development to agriculture and fragrances. The results of the study have been published in the leading journal Angewandte Chemie . They have led to the award of a major research grant from the Biotechnology and Biological Sciences Research Council (BBSRC) allowing the research team to expand on their discoveries in collaboration with industry. The idea is based on flow chemistry, in which chemical reactions take place continuously in a flowing stream of liquid within a tube or a pipe, as opposed to more traditional 'batch production' methods when chemicals are added into a vessel such as a flask and the product is then collected. Flow chemistry is changing the way chemical reactions are performed, providing safer, faster reactions and cleaner products.
