Plasticizers: Synthesis of phthalate esters via FeCl3
Plasticizers are extensively used in manufacturing of plastic materials, textiles, paints, cosmetics, etc. 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.
Plasticizers - Chemical Economics Handbook (CEH) | S&P Global
Overall, global plasticizer consumption will grow at a rate of about 3.5% per year in the next few years. Phthalate esters, based on phthalic acid, are the main types of plasticizers used since they satisfy a broad range of processing and performance requirements, as well as a large number of markets.
Synthesis of novel plasticizer ester end-capped oligomeric
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.
Uses of Phthalates and Other Plasticizers - U.S. Consumer
General Purpose Plasticizer: Offers the optimized balance of performance and costs Offers flexibility at the lowest cost Provides good low temperature properties and acceptable volatility Can be used with a variety of processing techniques Usable in almost every market segment Specialty Plasticizer: Imparts one or more special properties but may
Selected Fatty Acids Esters as Potential PHB-V
However, it seems that this amount of free fatty acids is still relatively low and shouldn’t affect the efficiency of this ester as a plasticizer. Ester 1 similarly to ester 4 is characterized by higher than other esters iodine value, respectively 77.6 g I 2 /100 g and 75.7 g I 2 /100 g, cause both of them were obtained by oleic acid
- Is liquefied wood flour ester a good plasticizer?
- The liquefied wood flour ester (PWF) showed good miscibility with PLA and good plasticization efficiency as shown by differential scanning calorimetry (DSC) and tensile testing. Tensile strain at break increased from a few percent for pure PLA to over 100 and 300% for the materials containing 10 and 30 wt-% of PWF.
- Is liquefied wood flour a good plasticizer for polylactide?
- RESULTS: Liquefied wood flour and rice bran derived esters were synthesized and evaluated as novel green plasticizers for polylactide (PLA). The liquefied wood flour ester (PWF) showed good miscibility with PLA and good plasticization efficiency as shown by differential scanning calorimetry (DSC) and tensile testing.
- Does plasticizing effect on starch polymers?

However, a m ajor setback swelling up the polymer. tested as plasticizers o n various polymers and materials.
- 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 .

- 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.
