Developmental toxicity evaluation of phthalic acid, one of the metabolites of phthalic acid esters, in rats

Toxicology Letters, 1997
The objective of this study was to evaluate the developmental toxicity of phthalic acid (PA), which is one of the metabolites of phthalic acid esters (PAEs). Pregnant rats were given PA at a dose of 0 (control), 1.25, 2.5, or 5.0% in the diet on day 7 through day 16 of pregnancy.

Phthalic Acid Esters

Food and Chemical Toxicology, 1984
The twentieth century can as properly be called the age of organic chemistry as it can the atomic age. The dramatic increase in the production of synthetic fibers, processed foods, pesticides, plastics, pharmaceuticals, and a thousand other materials has completely altered our immediate human environment and provided a wealth of new materials.

Toxicokinetics of Phthalic Acid: The Common Final Metabolite of Phthalic Acid Esters in Rats

Journal of Toxicology and Environmental Health, Part A, 2007
The toxicokinetic profiles of phthalic acid (PA), which is the common final metabolite of phthalic acid esters (PAE), were studied in rats after orally administering doses 20, 100, or 500 mg/kg. Concentrations of PA were determined in serum or urine by high-performance liquid chromatography (HPLC). The plasma concentrations of PA showed a biexponential

The diamagnetic susceptibilities of phthalic acid and phthalic anhydride

Proceedings of the Indian Academy of Sciences - Section A, 1949
1. The gram-molecular susceptibilities of carefully purified samples of phthalic acid and its anhydride are determined. The susceptibilities are: Phthalic acid, Xm=−81·24×10−6 Phthalic anhydride, Xm=−67·31×10−6 It is found that whereas the value of the gram-molecular susceptibility of phthalic acid found by Gray and Birse and ourselves is nearly ...

Aqueous solubility of m-phthalic acid, o-phthalic acid and p-phthalic acid from 298 to 483 K

Separation and Purification Technology, 1999
Abstract In an equilibrium cell, the aqueous solubility of m -phthalic acid ( m -PTA), o -phthalic acid ( o -PTA), p -phthalic acid ( p -PTA) was determined from 298 to 483 K using a method in which an excess amount of solubilizate was equilibrated with the aqueous solution and the saturated liquid compositions were analyzed by titration.

Interaction of Uranium(VI) with Phthalic Acid

Inorganic Chemistry, 2008
Phthalic acid, a ubiquitous organic compound found in soil, water, and in domestic and nuclear wastes can affect the mobility and bioavailability of metals and radionuclides. We examined the complexation of uranium with phthalic acid by potentiometric titration, electrospray ionization-mass spectroscopy (ESI-MS), and extended X-ray absorption fine ...

Phthalic acid excretion as an indicator of exposure to phthalic anhydride in the work atmosphere

International Archives of Occupational and Environmental Health, 1986
The concentration of phthalic acid was determined in the urine of nine subjects occupationally exposed to phthalic anhydride. For the determination, the urine samples were acidified, extracted with dimethyl ether, esterified with boron trifluoride/methanol and measured by electron capture gas chromatography.
