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.
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).
Synthesis of plasticizer ester using acid-functionalized
2.3. General procedure for synthesis of plasticizer ester. Weighed amounts of acid, alcohol, ionic liquid, cyclohexane were added to a flask with a reflux condenser, a water segregator and magnetic stirring apparatus. The esterification reaction was typically carried out for 2–12 h at the desired temperature with vigorous stirring.
Specialty Plasticizers for Rubber/Elastomers | Hallstar
The elastomer requires antioxidants, anti-ozonants, fungicides, plasticizers, tackifiers and flame-retardants as the occasion and severity of the application demands. It can be cured with sulfur or peroxide systems. High ACN polymers require high polarity plasticizers, low ACN polymers require low polarity plasticizers.
TP-95 | Hallstar Industrial
TP-95 is a highly compatible plasticizer that has been especially designed to impart maximum low temperature flexibility to elastomers, in particular high ACN nitrile, urethanes, polyacrylates and epichlorohydrin rubbers. TP-95 can also be using in vinyl formulations, either alone or in combinations with other plasticizers.
- 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.
- 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.

- 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.
- 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.
- How effective are esters in lowering TPE temperature?
- aDynamically vulcanized TPE,25 30 EP (D) M-70 isotactic polypropylene blend, plus 40 percent plasticizer phenolic resin system curative bTgs measured from tan delta peak at 10hz. The data clearly demonstrates that certain types of esters are extremely effective in lowering the Tg temperatures of both EPDM and PP components of the TPE.
