| titleOfInvention | Production method of bis (2-propyl) heptyl terephthalate |
| abstract | The application relates to the field of plasticizers, and particularly discloses a production method of bis (2-propyl) heptyl terephthalate. A method for producing bis (2-propyl) heptyl terephthalate comprises the following steps: step 1, preparing raw materials, namely weighing 2-propyl-1-heptanol, terephthalic acid and tetraisopropyl titanate, wherein the molar ratio of the 2-propyl-1-heptanol to the terephthalic acid is 2.0-4.0: 1, the dosage of the tetraisopropyl titanate is 0.01 to 0.20 percent of the total mass of the 2-propyl-1-heptanol and the terephthalic acid; step 2, esterification reaction, namely mixing and stirring the raw materials prepared in the step 1 at the temperature of 170-245 ℃ for 2-5 hours to obtain a crude product; step 3, post-treatment, namely neutralizing the crude product and washing the neutralized crude product for 1 to 3 times; and 4, decoloring, namely cooling the product subjected to the post-treatment in the step 3, decoloring and filtering to obtain a final product. The production method has the advantages of reducing the using amount of the catalyst and improving the production safety of the bis (2-propyl heptyl) terephthalate. |
