Alternative Plasticizers As Emerging Global Environmental and
Plasticizers are chem. compds. used to increase the softness and fluidity of polymer materials. Phthalate compds. constitute the most common class of compds. used as plasticizers. However, phthalate plasticizers, esp. the predominant di(2-ethylhexyl)phthalate, have been shown to have adverse effects on environment and human health.
The effects of phthalate ester exposure on human health: A
Phthalate esters (PAEs) are one of the most widely used plasticizers in polymer products and humans are increasingly exposed to them. The constant exposure to PAEs-contained products has raised some concerns against human health.

Then there is di(2-ethylhexyl) phthalate (DEHP), a common plasticizer used for PVC found in blood bags and in medical tubing. Reports detailing concerns about phthalate plasticizers exposure are abundant and the concerns around this plasticizer are well known [2,3,4,5]. When plasticizers are incorporated in PVC, rigidity of the latter reduces
Phthalate Ester Plasticizers: A New Class of Marine Pollutant
Abstract. Phthalate ester plasticizers have been detected in the open-ocean environment. Samples consisting of water, sediment, air, and biota from the Gulf of Mexico and of water and air from the North Atlantic were analyzed and found to contain two phthalate esters, di- (2-ethylhexyl) phthalate (DEHP) and di- n -dibutyl phthalate (DBP); the

They contain DEHP [Bis (2-ethylhexyl)] phthalate, a commonly used plasticizer. It is known to the state of California Environmental Protection Agency that this chemical causes cancer or reproductive toxicity. Compliance Materials used to make Nalgene PVC tubing are food grade and comply with USP Class VI regulations. Autoclaving
- What are phthalate plasticizers?
- From a chemical point of view, phthalate plasticizers come from an esterification reaction between phthalic anhydride and an alcohol with specific characteristics. Phthalates are the most used molecules in many sectors of industrial production.
- What are phthalate esters used for?
- Phthalate esters are used as plasticizers. 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. Phthalates are esters of phthalic anhydride.
- What is FECL 3-catalyzed esterification of alcohols with phthalic anhydride?
- FeCl 3-catalyzed esterification of alcohols with phthalic anhydride affords phthalate esters, under mild conditions. Phthalates are esters of phthalic anhydride. Phthalic anhydride (1) has been reacted with alcohols 2 to synthesize phthalate monoesters 3 and diesters 4 with the favor of latter compound that primarily used as plasticizers worldwide.
- Are ortho-phthalate esters a classified plasticizer?
- Ortho-phthalate esters have traditionally been the most dominant plasticizers, but regulatory concerns have led to the move away from classified substances to non-classified which includes high molecular weight ortho-phthalates and other plasticisers, especially in Europe.
- 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.
- What are phthalates and phthalic anhydride?
- Phthalates are esters of phthalic anhydride. Phthalic anhydride (1) has been reacted with alcohols 2 to synthesize phthalate monoesters 3 and diesters 4 with the favor of latter compound that primarily used as plasticizers worldwide. This two-steps process operates in single pot, in the presence of 10 mol% of FeCl3 as a catalyst.
