Bifunctional initiator 2,5-dimethyl-2,5-bis(hydroxyl-peroxide)hexane(DIOOH) is synthesized with 2,5-dimethyl-2,5-hexanediol(DIOL) as raw material, 30% hydrogen peroxide as oxidant and concentrated sulfuric acid as a catalyst for a more moderate conditions. The four factors such as amount of substance ratio of H_2O_2 and DIOL, amount of substance ratio of H_2SO_4 and DIOL, reaction time and reaction temperature are investigated via experiments on yield of DIOOH. The product structure is characterized by method of ~(13)C-NMR and MS. The results show that the optimization of synthesis technology processes are that amount of substance ratio of H_2O_2 and DIOL is 7, amount of substance ratio of H_2SO_4 and DIOL is 6, reaction time is 90 minutes and reaction temperature is 30 ℃. Under these conditions, yield of DIOOH is 71.6% and intrinsic viscosity of PAM can reach 277.6 dL/g when DIOOH initiates AM polymerization and mass concentration of DIOOH is 9 mg/L in polymerization system.
