| Abstract: | By catalytic esterification of tetrachlorophthalic anhydride (TCPA) with octyl alcohol, followed by the treatment of the resulting material with alkaline powder and absorbent,dioctyl tetrachlorophthalate(DOTCP),used as flame retardant plasticizer,was synthesized in high yield and quality, with the percent conversion of TCPA being 99.6%. The acid value and volume resistivity of DOTCP were 0.015mgKOH/g and 1.4×10 13 respectively. The optimal mole ratio was TCPA∶ octyl alcohol∶catalyst=1∶3∶1.24×10 -2 ,while the optimal reaction temprature was 210℃ and the reaction time was 3～3.5h. |
