What elements are in phthalates?
High phthalates include those with 7-13 carbon atoms in their chemical backbone, which gives them increased permanency and durability. Common types of high phthalates include diisononyl phthalate (DINP) and diisodecyl phthalate (DIDP).
What are phthalate esters for?
Phthalate esters (PEs) are by far the most produced and extensively used synthetic organic chemicals with notable applications in many industrial products such as vinyl upholstery, adhesives, food containers, packaging materials, printing inks, adhesives, cosmetics, paints, pharmaceuticals munitions, and insecticides …
What is the chemical name for phthalates?
Phthalate | C8H4O4 | ChemSpider.
What are plasticizers made of?
What are they made of? Plasticizers are produced by a reaction of an alcohol with an acid such as adipic acid, phthalic anhydride, and so forth. The choice of alcohol and acid will determine the type of ester that can be produced and hence the kind of plasticizer.
What does phthalates do to your body?
Phthalates, a family of industrial chemicals used to soften polyvinyl chloride (PVC) plastic and as solvents in cosmetics and other consumer products, can damage the liver, kidneys, lungs, and reproductive system.
Are phthalates polymers?
Phthalates constitute a diverse family of industrial compounds that are by far the most widely produced plasticizers up to date to increase the flexibility and workability of high molecular weight polymers. Their low melting point and high boiling point make them also very useful as heat-transfer fluids and carriers.
Is phthalate A Salt?
Potassium hydrogen phthalate, often called simply KHP, is an acidic salt compound. It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid.
What are the 3 types of plasticizers?
Explore various plasticization methods along with their benefits and learn how to select the right plasticizer from the main chemical classes of plasticizers: phthalates, benzoates, adipates etc.
What is plasticizer chemistry?
A plasticizer is an additive that is added to another material (usually a plastic or an elastomer) to make that material softer or more pliable.
Is phthalate harmful to humans?
Dangers of phthalates and DEHP Phthalates, a family of industrial chemicals used to soften polyvinyl chloride (PVC) plastic and as solvents in cosmetics and other consumer products, can damage the liver, kidneys, lungs, and reproductive system.
What are phthalate esters?
Phthalate esters are the di alkyl or alkyl aryl esters of phthalic acid (also called 1,2-benzenedicarboxylic acid, not be confused with the structurally isomeric terephthalic or isophthalic acids ); the name “phthalate” derives from phthalic acid, which itself is derived from the word ” naphthalene “.
What is the general chemical structure of phthalates?
General chemical structure of phthalates. R1 and R2 = C n H 2n+1; n = 4 – 15. Exact numbers are lacking, but the estimated worldwide production is about 4 300 000 t yr −1, of which c. 90% are used as plasticizers.
What is the UV maxima of/phthalate esters?
Phthalate esters would be expected to have UV maxima in the 230 nm and 270 nm regions. /Phthalate esters/ Hydroxyl radical reaction rate constant = 2.06X10-11 cu cm/molec-sec at 25 °C (est) US EPA; Estimation Program Interface (EPI) Suite.
Is di-isooctyl phthalate a diester or ester?
Diisooctyl phthalate is a phthalate ester and a diester. Di-isooctyl phthalate is an oily colorless liquid with a slight ester odor. Denser than water.
