Experimental Study on Recovery of BIT from Mother Liquor by Adsorption Resin
Production of BIT(1,2-benzeisothiazoline-3-one),a kind of raw material for producing broad-spectrum sterilization antiseptics,yields the mother liquor containing residue BIT.This paper deals with recovery of BIT from the mother liquor by use of macroporous adsorption resin.Experiment was conducted with three kind of macroporous resins referred to as A,B and C,and static adsorption capacity of the resins were investigated,based on which Resin A was found to be the best one.According to the experiment the optimum process parameters for recovering BIT was determined.
