To obtain graphene, we propose to use organic reagents and pure graphite exposed to ultrasound. Toluene, benzene, kerosene, and hydrogen peroxide are used as organic reagents. Results of experimental investigations of graphene in the systems under consideration are presented. Graphene structures have been obtained due to chemical interaction of these organic solvents with graphite. This led to the destruction of weak carbon bonds between graphite planes. We have found that the ultrasonic field provides a more effective destruction of the van der Waals bonds between graphite planes. The results of our investigation show that the use of the abovelisted organic solvents, unlike other methods using acids and alkali solutions, provides a more efficient method of obtaining graphene structures. Results of investigations of graphene structures by the method of electron paramagnetic resonance spectroscopy are presented and discussed.

为了获得石墨烯，我们建议使用暴露于超声波的有机试剂和纯石墨。甲苯、苯、煤油和过氧化氢用作有机试剂。介绍了所考虑系统中石墨烯的实验研究结果。由于这些有机溶剂与石墨的化学相互作用，已经获得了石墨烯结构。这导致石墨平面之间的弱碳键被破坏。我们已经发现超声波场可以更有效地破坏石墨平面之间的范德华键。我们的调查结果表明，与使用酸和碱溶液的其他方法不同，使用上述有机溶剂提供了一种更有效的获得石墨烯结构的方法。
