    The phthalate diesters are rapidly metabolized to the monoester both in the intestine and following absorption. The rate of hydrolysis is greater for the lower molecular weight esters. The monoester may undergo further oxidation of the alcohol side chain, but further hydrolysis is minimal.

5/5(3). Phthalate esters are an important class of chemicals widely used in commercial applications, primarily as plasticizers to soften vinyl, but are also used in consumer products.

This book reviews the state of the science of phthalate esters in the environment. A great deal of attention has been paid lately to release of phthalate esters (PAEs) from polyethylene terephthalate (PET) bottles into PET bottled drinking water due to their potential endocrine-disrupting effects.

Three kinds of PAEs, including diethyl phthalate (DEP), dimethyl phthalate (DMP) and dibutyl phthalate (DBP), were detected in 10 popular brands of PET bottles in Beijing, ranging Cited by: 1.

When phthalate esters are released into the environment, they tend to be concentrated from water into the soil and sediments because of their low water solubility. Phthalate ester contamination in soil is present in most parts of the by: Phthalate esters are contaminants in many products commonly found in the laboratory.

It is particularly important to avoid the use of plastics because phthalates are commonly used as plasticizers and are easily extracted from plastic materials. Phthalate esters are prepared by the esterification of phthalic anhydride with two molar equivalents of an alcohol or an alcohol blend.

Although almost any alcohol can be used to make a phthalate ester, it is usually only the esters of the C6 to C13 alcohols that are useful as PVC plasticizers.

Although almost any alcohol can be used to make a phthalate ester, it is usually only the esters of the C6 to C13 alcohols that are useful as PVC plasticizers. Phthalates are a family of compounds some of which primarily are used to soften or “plasticize” polyvinyl chloride (PVC), or vinyl.

The High Phthalates Panel (HPP) of the American Chemistry Council (ACC) was formed in with a mission dedicated to promoting the benefits of esters of phthalic anhydride based on C9 and higher alcohols (C9.

Male Sprague Dawley rats were exposed to dibutylphthalate (DBP) by inhalation with concentrations of, and ppm in the air for 5 days. The concentrations were considered relevant to human exposure.

No quantitative changes were observed in liver microsomal cytochrome P related enzymes, but significant increase was observed in the liver microsomal metabolism of benzo(a)pyrene.

Phthalate esters are widely distributed in the ecosystem due to their ubiquitous use as plasticizer compounds. Weschler identified phthalate esters as a significant component of Arctic aerosol.

Phthalate ester plasticizers that long have dominated the flexible PVC market have some serious non-phthalate competition, including some newer alternatives. Health, environmental concerns give non-phthalate plasticizers a push: new and improved formulations are displacing leading plasticizer DEHP; DINP's future is also now shakier.

We report that aryl phthalate esters are robust self-immolative linkers. This linker is easy to conjugate and releases output phenols upon cleaving a fluoride-sensitive mask to yield a benign phthalic acid byproduct, making these linkers potentially useful as fluoride sensors and promising for use in biological and materials by: Phthalate Reference Standards The Consumer Products Safety Commission (CPSC) has proposed banning the use of several phthalates in materials for children’s toys.

Self-immolative aryl phthalate esters were conjugated with cleavable masking groups sensitive to light and hydrogen peroxide. The phthalate linker releases the fluorescent dye 7-hydroxycoumarin upon exposure to light or H2O2, respectively, leading to an increase in fluorescence.

Phthalates. Phthalates are a group of aromatic chemicals containing a phenyl ring with two attached and extended acetate groups. They are typically colorless liquids used to make plastics more flexible and resilient, and are often referred to as plasticizers.
