Trimellitic acid trioctyl by trimellitic anhydride: octanol is 1: 0.5 (molar ratio), in the presence of a catalyst composite aluminum hydroxide and sodium hydroxide, 160 ~ 220 ℃ esterification of 120 to 180 minutes in the system too, the product ester content of 99.5%, a volume resistivity of 8.4 × 1011Ω · cm. Trimellitic acid trioctyl as a plasticizer used in cable compound, a tensile strength of 26.3MPa. An elongation of 260%, the embrittlement temperature of -37 ℃. Aging at 100 ℃ 7 Tian weightlessness 3.1%, maintaining an elongation of 92%.
Tengzhou City Technology Co., Ltd. Xiangying analysis developed GC7990 gas chromatograph measured the success of the industrial trimellitic acid trioctyl purity and impurity, satisfactory results are welcome.
