Failing to mix reactions in heterogeneous or industrial systems could cause numerous issues and might even be dangerous, preprint claims

Chemical engineers in the Netherlands have weighed in on the debate over whether to stir chemical reactions or not, following the publication of a study that suggested mixing doesn’t matter. In response, the team argues that stirring remains critical for reproducibility, selectivity and scalability, particularly in heterogeneous or industrially relevant systems.
