Minimizing the Effect of Plasticizer Supply Disruptions - GEON
Recognizing a shortage of 810 alcohol was imminent and would affect 810TM plasticizer supply, GEON’s cross-functional Synthetic Esters team proactively began developing a replacement plasticizer. When the formulator reached out to GEON with their dilemma, the team was already prepared with a solution.
Synthesis of novel plasticizer ester end-capped oligomeric lactic acid
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).
Plasticizer < Our Business | OCI
Plasticizers are categorized as phthalate-based, trimellitate-based, phosphoric acid-based and epoxy-based depending on the base material. It is produced by the ester reaction between alcohol such as Octanol (2-EH), INA, etc., and acids such as PA, TPA, TMA, etc. Depending on the base material, different grades of plasticizers are produced.
Furan-2,5-and Furan-2,3-dicarboxylate Esters Derived
In brief, these synthetic compounds have promising feasibility as biobased plasticizers. Moreover, another interesting point is that the properties of furan-2,3-dicarboxylic acid derivatives were studied for the first time and herein reported.
Phthalates and non-phthalate plasticizers in sediment from Korean
Phthalic Acid Esters (PAEs) are widely used as plasticizers in industrial sectors for enhancing the properties of polymers, such as flexibility, softness, and workability; more common plastic
- Which phthalates and alternative plasticizers were detected in the coastal zone of Korea?
- Phthalates and alternative plasticizers were detected in all sediment samples from the coastal zone of Korea. DEHP and DEHT were the dominant phthalates and NPPs, respectively. The spatial distribution of phthalates and NPPs along Korea's coast is governed by harbor-zone activities and sedimentary organic carbon.
- Are phthalates and non-phthalate plasticizers found in coastal sediment?
- Korea is the world's largest consumer of plastic, with increasing production and consumption ( European Plastics and Rubber Machinery, 2016 ). The present study assesses the occurrence, spatial distribution, and potential contamination sources of phthalates and non-phthalate plasticizers in coastal sediment from Korean coastal waters.
- Do phthalates and non-phthalate plasticizers pose ecological risk to benthic organisms?
- Given the occurrence of phthalates and non-phthalate plasticizers, including DEHP, further studies are required to identify the contamination sources and assess the ecological risk to benthic organisms posed by these contaminants in coastal environments. Fig. 5 Cumulative distribution (%) of DEHP concentrations measured in sediments from.
- Are non-phthalate plasticizers contaminating the coastal environment?
- All NPPs were detectable in all sediment samples, indicating widespread contamination of the coastal environment by these plasticizers. DEHA and DEHT were detected in almost all sediment samples (detection rate: 98%), also suggesting major contamination by non-phthalate plasticizers.
- Are phthalate plasticizers contaminating the environment?
- DEHA and DEHT were detected in almost all sediment samples (detection rate: 98%), also suggesting major contamination by non-phthalate plasticizers. The occurrence of phthalates in the environment is related to production and consumption in industrial markets ( Gao and Wen, 2016 ).
- Are phthalates a plasticizer?
- Phthalates are representative plasticizers used in a variety of commercial and industrial applications since the 1930s ( Sun et al., 2013Net et al., 2015aLi et al., 2017Mi et al., 2019 ).
