Method 606: Phthalate Ester - US EPA
used as plasticizers and are easily extracted from plastic materials. Serious phthalate contamination can result at any time, if consistent quality control is not practiced. Great care must be experienced to prevent such contamination. Exhaustive cleanup of reagents and glassware may be required to eliminate background phthalate contamination.

- What is dioctyl phthalate (DOP)?
- 1. Introduction Dioctyl phthalate (DOP) is one of the most widely used plasticizers with low volatility and high plasticizing efficiency. Although new product like dioctyl terephthalate is more recommended, DOP accounts for more than half of the market share for plasticizers.
- What is phthalic anhydride (PA) and 2-ethylhexanol (eh)?
- It has been generally utilized for the flexible polyvinyl chloride (PVC) plastic production owing to its low cost. DOP is traditionally synthesized by the catalytic esterification between phthalic anhydride (PA) and 2-ethylhexanol (2-EH) . The synthetic process includes two-step reactions of esterification: (1) (2)
- Where can I buy phthalic anhydride and p-toluenesulfonic acid?
- Materials Dioctyl phthalate, phthalic anhydride, 2-ethylhexanol, n-tridecane, choline chloride, imidazole, and p -toluenesulfonic acid are purchased from Adamas-beta (Shanghai, China) with purity above 99%.
- How does 2-eh affect DOP yield?
- The excess of 2-EH can speed up the attainment of phase splitting, which is favorable for the forward reaction and hence increasing DOP yield. However, phase splitting will reduce the possibility of contact between reactants and DES, which delays the reaction to attain chemical equilibrium. 5.2. Kinetic modelling
- What is a high DOP yield after a three-stage reaction?
- At the condition of 130 °C (all reactors), 2-EH to PA mole ratio of 2.2 in PR, and DES mole fraction of 7.53 % (R1, R2 and R3), a high DOP yield of 98.61 % can be achieved after three-stage reactions. In Table 3, the composition of both phases in D1, D2 and D3 predicted by COSMO-RS were listed.
- Is 2-eh esterification endothermic?
- The positive correlation between temperature and DOP yield validates that the esterification of 2-EH with MEPA is endothermic. Increasing temperature can benefit the forward reaction, making more reactant molecules to be activated by acquiring sufficient kinetic energy to form products. 5.1.3. Effect of reactants mole ratio
