Industrial Validation: A commodity chemicals manufacturer was seeking a feasible process to obtain polymer materials. Despite narrow profit margins Apeiron successfully applied olefin metathesis in the bulk chemistry process. In just one month, our team managed to meet both, process and product parameters requested by the customer. With the catalyst loading as low as 8 wt ppm, costs of the metathesis step were reduced threefold relative to the threshold set for economic reasons. Importantly, the optimization was conducted on unprocessed materials provided by the customer. Final catalyst cost reached 0.45 euro per 1 kg of the product.
