WO2017204913A3 - Purified plasticizers, production and use
The purified aromatic esters can be produced by esterifying carboxylic acid with methyl or ethyl alcohol, separating the resulting methyl or ethyl esters from the carboxylic acid and any byproduct impurities, and then transesterifying the methyl or ethyl esters with C 4 to C 14 alcohol to produce the purified aromatic esters.
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto

24.14 Other Plasticizers. This category includes a variety of different plasticizers including polyol esters, nonepoxy bioplasticizers, and miscellaneous plasticizers. In 2005, Danisco introduced their new bioplasticizer, Soft-n-Safe (SNS). This plasticizer is based on castor oil, where the oil is hydrogenated, then transesterified, and
US Patent for Purified plasticizers, production and use
Purified plasticizers, production and use Apr 11, 2017 - ExxonMobil Chemical Patents Inc. This disclosure relates to methods for producing purified aromatic esters useful as plasticizers, to the purified aromatic esters, and to polymer compositions containing the purified esters.
Purified Plasticizers, Production and Use
The purified aromatic esters can be produced by esterifying carboxylic acid with methyl or ethyl alcohol, separating the resulting methyl or ethyl esters from the carboxylic acid and any byproduct impurities, and then transesterifying the methyl or ethyl esters with C4 to C14 alcohol to produce the purified aromatic esters.
- What is a plasticizer?
- In general, plasticizers can be defined as low molecular weight (between 300 and 600) , high boiling point materials which are added to a film-forming polymer to enhance its flexibility, durability, processability, and workability . Their addition can avoid shrinking during storage , and in some cases reduce costs .
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- Can plasticizers be used to make plastic products?
- The use of plasticizers for plastic products manufacture is not a new practice. Its application to modify polymer characteristics began in the 1800s. In these early days, manufacturers of celluloid or celluloid lacquers used natural camphor and castor oil for plasticization purposes, but these were unsatisfactory for many end uses.
- What are natural based plasticizers?
- Nowadays, there is increasing interest in the use of natural-based plasticizers that are characterized by low toxicity and low migration. This group includes epoxidized triglyceride vegetable oils from soybean oil, linseed oil, castor-oil, sunflower oil, and fatty acid esters (FAEs) .
- Could liquefied wood flour derived plasticizer be a biobased polylactide plasticizer?
- CONCLUSIONS: The results demonstrate that the synthesized liquefied wood flour derived plasticizer could have great potential as a biobased polylactide plasticizer. © 2012 Society of Chemical Industry PDF | Plasticizers are chemical additives added into polymers to influence desirable mechanical properties such as processability and ductility.
- Are plasticizers biodegradable?
- Plasticizers are additives used to ensure flexibility to polymer blends and thereby to increase their processability. As the typical plastic component phthalates and other fossil-based components contribute environmental issues since such compounds are not biodegradable.
