A novel phenylboric acid functionalized L64 was prepared by acyl chlorination reaction which introduced boric acid groups into the L64 template molecul.The successful modification of L64 was proved by the study of the cloud point properties and variation of functionalized L64 with phenylboronic acid.The prepared phenylboronic acid functionalized L64 was used as a flotation collector in the affinity flotation experiment of catechol,and the factors affecting the recovery rate of catechol were optimized.The optimal flotation process conditions were obtained:0.34 g of collector,2 mg of catechol,15 mL/min nitrogen flow rate,and 40 min flotation time.
