Abstract: Gas-liquid jet reactor is a reactor with high intensity. The droplet size scale and distribution in the reactor have crucial effects on the yield and selectivity of reactions. In this paper，experimental equipment was established for measuring droplet size distribution in a gas-liquid jet reactor. The technique of PLIF（Planar laser induced florescence）was used to investigate the droplet size distribution in the jet reactor under different gas and liquid flow rates. The result shows：①In the case of constant liquid flow rate，the jet inside the mean droplet diameters decreases and the distribution of droplet diameters becomes narrower with the increasing of gas flow rate. ②In the case of constant gas flow rate，the mean droplet diameters became smaller and the distribution range became narrower with the increasing of liquid flow rate.
