Databook of Plasticizers - 2nd Edition
Databook of Plasticizers, Second Edition, contains data on the most important plasticizers in use today, including over 375 generic and commercial plasticizers. The data comes from a range of sources beyond plasticizers' manufacturers, allowing for a detailed comparison of properties between different plasticizers.
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.

Improving Processing of PET, the World’s Most Recycled Plastic
Phthalates are low molecular weight monoesters made from orthophthalic acid. By comparison, PET is a high molecular weight polyester made from terephthalic acid and these forms are chemically very different. Phthalates (i.e. phthalate ester plasticizers) are not used in the manufacture of PET, and PET itself is not a phthalate.
The design and synthetic routes of C26-DGE and the commercial...
A castor oil-derived diglycidyl ester plasticizer (C26-DGE) was prepared and incorporated into poly (vinyl chloride) (PVC) for the first time. The chemical structure of the product was
Method 606: Phthalate Ester - US EPA
It is particularly important to avoid the use of plastics because phthalates are commonly 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
- 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 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 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 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.
- What is an ester plasticizer?
- An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.1 For general performance applications, compounders require moderate performance in several areas without particular emphasis on any one.
- Can FECL 3 be used as a catalyst for phthalate esterification?
- Synthesis of phthalate esters. Now we have found that a neutral and cheap FeCl 3, as a Lewis acid catalyst for esterification, promotes nucleophilic addition of alcohols 2 to phthalic anhydride (1), at much lowered temperatures (50 or 100 °C) affording commercially valuable phthalates, in a simplest way so far ever reported.
