Synthesis and Characterization of some New Amic acid and Imides and study the Biological Activity

open access: yesTikrit Journal of Pure Science, 2023
This study includs the synthesis of some new Amic acid and Imides, starting from the esters [S1] of Terephthalic acid which then converted to its hydrazide [S2] then to amic acid derivatives [S3-S7] and finally with imides [S8-S12].

Plasticizers: Synthesis of phthalate esters via FeCl3-catalyzed nucleophilic addition of alcohols to phthalic anhydride

open access: yesResults in Chemistry, 2021
Phthalates are esters of phthalic anhydride. Phthalic anhydride (1) has been reacted with alcohols 2 to synthesize phthalate monoesters 3 and diesters 4 with the favor of latter compound that primarily used as plasticizers worldwide.

Microbiology combined with metabonomics revealing the response of soil microorganisms and their metabolic functions exposed to phthalic acid esters

open access: yesEcotoxicology and Environmental Safety, 2022
As microplastics became the focus of global attention, the hazards of plastic plasticizers (PAEs) have gradually attracted people's attention. Agricultural soil is one of its hardest hit areas. However, current research of its impact on soil ecology only

Spatial distribution model of DEHP contamination categories in soil based on Bi-LSTM and sparse sampling

open access: yesEcotoxicology and Environmental Safety, 2022
Soil pollution is a serious threat to human life and development. Different remedial measures are applied to soils with different levels of contamination. The degree of soil contamination in different areas is generally evaluated and categorised based on

Anaerobic degradation process of phthalic acid esters

open access: yes浙江大学学报. 农业与生命科学版, 2006
Ten phthalic acid esters (PAEs) were tested anaerobically to assess their potential for biogas production. Results showed that biogas production decreased with the increasing alkyl chain length of PAEs resulting in its increased half-life.

The estrogenic activity of phthalate esters in vitro [PDF]

open access: yes, 1997
A large number of phthalate esters were screened for estrogenic activity using a recombinant yeast screen. a selection of these was also tested for mitogenic effect on estrogen-responsive human breast cancer cells.

Retention of Phthalates in Wine Using Nanomaterials as Chemically Modified Clays with H20, H30, H40 Boltron Dendrimers

open access: yesNanomaterials, 2023
The presence of phthalic acid esters in wines presents a major risk to human health due to their very toxic metabolism. In this paper, aluminosilicate materials were used, with the aim of retaining various pollutants and unwanted compounds in wine.

Phthalic acid esters (PAEs) in the food chain

open access: yesCzech Journal of Food Sciences, 2006
Phthalic acid esters (PAEs) rank among the primary risk pollutants and their adverse effects may endanger the environmental balance and affect the ontogenetic development of live organisms and their body functions. Therefore, the aim of this study was to
