Method for producing trioctyl trimellitate with trimellitic acid
ActiveCN101429126ATemperature is not harshLower requirementOrganic compound preparationCarboxylic acid esters preparationTrimellitic acidOctanol
The invention relates to a method for producing trioctyl trimellitate through using trimellitic acid. Intermediate products of trimellitic acid and methanol in the process of producing the trimellitic anhydride are esterified to generate trimethyl trimellitate; the trimethyl trimellitate and 2-ethylhexanol (commonly called asoctanol) are subjected to ester exchange to produce trimellitate (2-ethyl) trihexyl ester (trioctyl trimellitate). The method of methyl esterification and ester exchange can reduce requirement on a technology and equipment so that the intermediate product of the trimellitic acid in the process of producing the trimellitic anhydride is flexibly utilized.

Heat-resistant polyvinyl chloride material, preparation method thereof and wire
ActiveCN104804332AImprove low temperature brittlenessIncrease costPlastic/resin/waxes insulatorsElastomerHeat stability
The invention provides a heat-resistant polyvinyl chloride material which is prepared from the following raw materials: 100 parts of polyvinyl chloride resin powder, 45-52 parts of trioctyl trimellitate and 22-31 parts of a filling agent which comprises calcium carbonate and kaoline, 3-8 parts of Ca-Zn composite stabilizer, 4-7 parts of ethylene-n-butyl acrylate-hydroxy elastomer and 1.5-5 parts of a flame retardant; the flame retardant comprises Sb2O3 and / or an Sb2O4 substitute. The heat-resistant polyvinyl chloride material provided by the invention is higher in low-temperature fragility and lower in cost; furthermore, the heat-resistant polyvinyl chloride material is higher in mechanical physical performance and heat stability. An experiment result shows that the low-temperature fragility of the heat-resistant polyvinyl chloride material is -11 DEG C to -21 DEG C. The invention further provides a preparation method of the heat-resistant polyvinyl chloride material and a wire.
