description The invention relates to a production method and a production system of beta-isophorone, alpha-isophorone is used as an initial raw material to prepare beta-isophorone, and the adopted production system comprises a heater for heating and vaporizing alpha-isophorone, a gas-liquid separator, a packed column filled with a catalyst and a rectifying tower which are arranged in sequence; the production method comprises the steps that alpha-isophorone is heated and vaporized through the heater and then enters the gas-liquid separator to be subjected to gas-liquid separation, a gas material is obtained, the gas material enters the packed column to be catalyzed through the catalyst and then enters the rectifying tower to be separated, and beta-isophorone is obtained. The liquid-solid phase reaction is converted into the gas-solid phase reaction, so that the loss of the catalyst is greatly reduced, the catalyst is prevented from accumulating in the liquid phase and causing side reaction, and the instability of the prod
