Plasticizers: Synthesis of phthalate esters via FeCl3
Further optimization of the reaction allowed us to isolate diisopentyl phthalate (4c) in 82% by using 5 mol equiv of the alcohol 2c (i.e. 100 mmol) at 100 °C reaction temperature (entry 4). Similarly, dibutyl phthalate (4d), which is extensively used as a plasticizer, also can be produced by using n-butanol (2d) (entries 5 and 6
Diverging trends of plasticizers (phthalates and non
Background European chemicals management aims to protect human health and the environment from legacy and emerging contaminants. The plasticizer market changed in response to the restriction of low molecular weight (LMW) phthalate plasticizers such as Di (2-ethylhexyl) phthalate (DEHP) due to their hazardous properties. We investigated patterns and trends of 19 regulated and emerging
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.
Plasticization of Butyl Methacrylate–Methacrylic Acid
Abstract The effect of a crystallizing plasticizer dimethyl phthalate on the glass transition temperature of butyl methacrylate copolymer with methacrylic acid (7.6 mol %) is studied in the range of 80–450 K by differential thermal analysis. The solubility of dimethyl phthalate in the copolymer at the melting temperature of the plasticizer is determined by calorimetry. Using the obtained
Phthalates in Food Packaging and Food Contact Applications
Phthalates in Food Packaging and Food Contact Applications Ortho -phthalates, often referred to as “phthalates,” are chemicals used in plastic products (most commonly in the specific type of...
