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.
