    摘要： Disclosed is a method of producing a compound which includes: obtaining a reaction product which contains a monoester compound represented by the following formula (I) and 1,4-cyclohexanedicarboxylic acid dichloride and/or 1,4-cyclohexanedicarboxylic acid, by reacting in an organic solvent a hydroxy compound represented by the formula Q-OH (where Q represents organic group which may have a substituent) with 1,4-cyclohexanedicarboxylic acid dichloride and/or 1,4-cyclohexanedicarboxylic acid; and mixing the reaction product with an acidic aqueous solution, where A represents hydroxyl group or chlorine atom and Q is as defined above.

    摘要： The present invention relates to a process for preparing a terephthalic diester by reacting terephthalic acid with at least one alcohol, wherein terephthalic acid is suspended in the alcohol in a dispersing tank, the preliminary suspension is passed from the dispersing tank into a reactor and converted in the presence of an esterification catalyst, a reaction suspension is drawn off from a region between the upper region and the lower region of the reactor, a first stream of the reaction suspension is recycled into the upper region of the reactor and a second stream of the reaction suspension is introduced into the lower region of the reactor, and the reaction suspension is thus mixed, wherein the stream drawn off and/or the first stream is passed through a heat exchanger outside the reactor and heated; and water of reaction is distilled off together with the vapor as alcohol-water azeotrope, the vapor is at least partly condensed, the condensate is separated into an aqueous phase and an organic phase and the organic phase is at least partly recycled into the reaction system.

    摘要： The present invention relates to a plasticizer composition and a resin composition including the same, and can provide a plasticizer composition in which three types of terephthalate-based materials and three types of cyclohexane 1,4-diester-based materials are mixed, and by which environmental friendliness can be secured, mechanical properties such as tensile strength and an elongation rate, physical properties such as migration properties and volatile loss can be improved to levels equal to or higher than those of existing products, and effects of improving processability and plasticizing efficiency can be expected, and a resin composition including the same.
