Synthesis of novel plasticizer ester end-capped oligomeric
In this work, a novel high efficiency plasticizer, an ester-capped oligomeric lactic acid mixture (EOL), was successfully synthesized by a two-step esterification reaction, with L -lactic acid as the main raw material. The structure of EOL was characterized by using FT-IR, 1 H NMR and time of flight mass spectrometry (TOF-MS).
Plasticizers: Synthesis of phthalate esters via FeCl3
Plasticizers are extensively used in manufacturing of plastic materials, textiles, paints, cosmetics, etc. Phthalate esters are used to prepare in harsh conditions, at a higher reaction temperature. FeCl 3-catalyzed esterification of alcohols with phthalic anhydride affords phthalate esters, under mild conditions.

Purity of plasticizer is determined by ester content using titration. 23 For this purpose, 2 g of plasticizer are saponified with 0.5N KOH under reflux for 1 to 4 hours (depending on ester type). The content is
Identifying Citric Acid Esters, a Class of Phthalate
Citrate acid esters (CAEs) have been proposed as a class of phthalate substitute plasticizers; however, information on their occurrence in indoor environments is rare. By using liquid chromatography coupled with a quadrupole-Orbitrap mass spectrometer, we developed an integrated strategy that can be applied for target, suspect, and characteristic fragment-dependent screening of CAEs.

- How are ester plasticizers selected?
- Ester plasticizers are selected based upon cost/performance evaluation. The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer.
- What is a general performance ester plasticizer?
- Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length. Ester plasticizers are commonly used only for their as-molded, low-temperature contribution.
- Why do we use ester plasticizers?
- Ester plasticizers make it possible to process elastomers easily while also providing flexibility in the end-use product. Plasticizer–elastomer interaction is governed by many factors, such as solubility parameter, molecular weight and chemical structure. Ester plasticizers are selected based upon cost/performance evaluation.
- How to choose a high-performance ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer. 1.
- Can polymeric esters enhance a high-performance elastomer?
- One example of how polymeric esters can enhance a high-performance elastomer is depicted in Figure 3. High-saturated nitrile is used in many high-heat applications. The use of 8-10 trimellitate is well documented as the plasticizer of choice for HNBR.
- Are plasticizers suitable for elastomers and high-temperature polymers?
- Plasticizers commonly used for the traditional and the high-temperature polymers are extractable, incompatible or too volatile. This paper provides information on plasticizers that are designed for traditional elastomers and high-performance polymers.
