摘要：n-B18H22 is a potential blue laser material. In order to study the stability of n-B18H22 in aqueous solution, the hydrolytic reaction kinetic of n-B18H22 at various pH values and temperatures was studied by fluorescence spectroscopy. The results showed that n-B18H22 hydrolysis rate was accelerated by increasing temperature, and the trend showed that n-B18H22 hydrolyzed faster in low pH than in high pH solutions at the same temperature. The hydrolysis of n-B18H22 solution is second-order reaction at lower temperature (298.15K-323.15K), the activation energy is 52.37 kJ.mol-1 and pre-exponential factor (A) is 7.9x1010. The work described here is significant for future studies of the properties of n-B18H22 in aqueous solution.
