Researchers from various institutions, including the University of Oxford, have devised an innovative and environmentally friendly technique for manufacturing fluorochemicals. By drawing inspiration from biomineralization processes that naturally form teeth and bones, they have managed to sidestep the use of harmful hydrogen fluoride gas, a toxic substance traditionally used in fluorochemical production.
The cutting-edge method, which has led to the formation of a company called FluoRok for its commercialization, employs solid-state calcium fluoride (CaF2) activated by a biomineralization-inspired process. This method was realized by grinding CaF2 with powdered potassium phosphate salt using a mechanochemical process, yielding a product known as Fluoromix. With a successful synthesis rate of up to 98%, this process is capable of producing over 50 different fluorochemicals directly from CaF2.
This development, published in the prestigious journal Science on July 20, has the potential to fundamentally alter the $21.4 billion fluorochemical industry, which encompasses critical applications such as polymers, agrochemicals, pharmaceuticals, and lithium-ion batteries. The current process of generating fluorochemicals, reliant on hydrogen fluoride (HF), is energy-intensive and has led to several accidents and environmental damage over the past decades. The novel approach not only avoids the production of HF but also streamlines the supply chain and reduces energy requirements, aligning with future sustainability goals.
FluoRok, the newly created spin-out company, is focused on taking this technology to market, aiming to provide safer, sustainable, and cost-effective fluorinations. This advancement is being hailed as a paradigm shift for global fluorochemical manufacturing, reflecting a concerted push towards greener and more responsible chemical processes.
The researchers, including lead authors Calum Patel and Professor Véronique Gouverneur from the University of Oxford, are optimistic that this research may inspire further disruptive solutions to challenging chemical issues, benefiting society at large. The direct use of CaF2 for fluorination, a problem that has been unresolved for decades, marks a significant step towards sustainable chemical manufacturing that can be applied across academia and industry.
