Scientists Center for New Functional Materials of Novosibirsk State University received a patent for a method for producing a mixture of 2-cyclohexenylcyclohexanone isomers—a substance used as a key intermediate in the creation of flame retardants. These compounds are used to reduce the flammability of modern materials, including composites used in transportation and industry.
The development is part of a project aimed at improving fire safety in transport systems. The project is being implemented with financial support from the NTI Foundation. Composite materials are increasingly being used in aviation, rail, and other technology.
"New composite materials are currently being actively implemented because they significantly reduce structural weight and improve transport efficiency, as well as offering excellent performance properties. However, they are more flammable than metal alloys and can emit toxic products when ignited," noted Mikhail Yadrenkin, a senior researcher at the NSU Center for New Functional Materials.
To solve this problem, scientists are developing special additives—flame retardants—that reduce the flammability of materials. Many modern flame retardants are based on a key structural fragment known as DOPO. This is essentially a base to which other components can be added, which will consequently alter the additive's properties, such as the compatibility of the flame retardant with a particular polymer base of a composite material. However, DOPO production requires affordable and effective raw materials, and a patented synthesis method has been developed specifically for this purpose.
As explained by Dyan Ok Tong, head of the Laboratory of Fluorinated Compounds at the N. N. Vorozhtsov Novosibirsk Institute of Organic Chemistry, Siberian Branch of the Russian Academy of Sciences, the idea is to create a more convenient and technologically advanced process for producing the DOPO precursor.
"We've improved a well-known synthesis method by replacing hard-to-find and limited-supply reagents with cheaper and more readily available alternatives without sacrificing efficiency. Furthermore, we've managed to scale the process from laboratory conditions to a 20-liter reactor," he said.
The patent awarded is not just a scientific result, but a step toward creating a fully-fledged technological chain. According to the researchers, temporary technological regulations have already been developed as part of the project, and the first samples of polymer binders with new flame retardants have been produced and tested for fire resistance.
"Our goal is not only to synthesize new substances, but also to develop technologies to a level where they can be scaled up and implemented in industry," emphasized Mikhail Yadrenkin.
This development is of significant importance for Russian industry, where the production of modern flame retardants is still limited. These new technologies will enable the creation of low-flammability materials for aviation, rail transport, and other industries with particularly stringent safety requirements.
