Ester plasticizers for polyvinyl chloride | SpringerLink
The review covers information from patents and papers that have been published in the past 5 years and deal with the synthesis of ester plasticizers for polyvinyl chloride. The main trends in the progress of this field are analyzed. Data on new esterification catalysts are presented. Particular attention is paid to plasticizers derived from terephthalic acid, which show promise for replacing

processes for producing plasticizers; and development of new environmentally friendly (“green”) low-toxic plas-ticizers derived both from petroleum chemical products and from renewable vegetable raw materials. ESTERIFICATION CATALYSTS Ester plasticizers are prepared by esteri cation of carboxylic acids or their anhydrides with alcohols in
Special Issue "Green Plasticizers for Polymers" - MDPI
The scope of this issue ranges from synthesis of green plasticizers, enhancement of physical and rheological properties, migration of plasticizers upon disposal, relationships between plasticizers and human health, and life-cycle-assessment. Particular emphasis will be placed on the design and evaluation of new green plasticizers, using the
US4284793A - Method for producing plasticizers - Google Patents
The method for producing a plasticizer according to the present invention is characterized in treating the ester obtained by reacting phthalic anhydride with an alcohol having 4-18 carbon atoms in the presence of a tetraalkyl titanate or a polymer thereof, with a solid alkali and adsorbing agent(s) in the absence of water.
RU2114819C1 - 2-ethylhexanol-based ester production process
The prepared esters can be successfully used for the plasticization of polyvinyl chloride and its copolymers, polyvinyl butyral, artificial and natural rubbers and other polymers, as well as...
- 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 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.
- How are polymeric plasticizers produced?
- Polymeric plasticizers are produced by reacting a dibasic carboxylic acid with a glycol or a mixture of different dibasic glycols. When the molecules are reacted, the chain propagation or building may be terminated by the use of monofunctional carboxylic acids or alcohols. Some polymeric plasticizers are also produced using no terminator.
- How to choose a high-performance ester plasticizer?
