Distribution of microplastics and phthalic acid esters during dry anaerobic digestion of food waste and potential microbial degradation analysis.

open access: yesBioresource Technology
Food waste (FW) and its biogas residue were considered as sources of terrestrial microplastics (MPs) and phthalic acid esters (PAEs) contamination. However, there was a lack of research and understanding of the MPs and PAEs pollution problem in FW dry ...

New Biobased Polyester Polyols With Tunable Tg Values From 4‐Vinylguaiacol‐Derived Monomers

open access: yesChemSusChem, Volume 19, Issue 15, 14 August 2026.
Biobased low‐molecular‐weight polyesters were obtained by ROCOP of guaiacol‐derived epoxides with cyclic anhydrides. Varying the length of the acyl moieties on the epoxides and the cyclic anhydride structures, it is possible to tune the Tg's within an 80 ºC wide temperature range.

Industrial alkyd resins: characterization of pentaerythritol and phthalic acid esters using integrated mass spectrometry

open access: yes, 2015
RATIONALE: Alkyd resins are synthetic polyesters used as paints and coatings. Current approaches for their analysis do not allow the characterization of pentaerythritol and phthalic acid esters, whose detection is interesting to fully characterize the ...

Active and Versatile ROP Aluminum Catalysts for the Controlled Limonene Oxide Polymerization and Copolymerization With Anhydrides

open access: yesChemCatChem, Volume 18, Issue 13, 14 July 2026.
Highly active aluminum catalysts for the ring‐opening copolymerization of LO and PA able to produce syndiotactic alternating copolyester within 3 h are presented. The role of DMAP as cocatalysts for the copolymerization is key and is involved in the opening of the anhydride, however, it blocks the catalytic activity for the LO ROP.

The Action of the Grignard Reagent on ο-Phthalic Esters [PDF]

open access: yes, 1909
1. In spite of the great analogy existing between o-phthalic acid and succinic acid, the action of the Grignard reagent upon o-phthalic esters differs from that upon succinic esters in producing derivatives of phthalide, instead of producing glycols.

Phthalic acid mimics 17β-estradiol actions in WISH cells

open access: yes, 2001
The object of this study was to evaluate whether phthalic acid, which is one of the metabolites of phthalic acid esters, exerts estrogenic actions in WISH cells, an immortalized cell line derived from human amniotic tissue.

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

open access: yesEnvironmental Progress &Sustainable Energy, Volume 45, Issue 4, July/August 2026.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

High-throughput analysis of total plasma fatty acid composition with direct in situ transesterification. [PDF]

open access: yes, 2010
Plasma fatty acid (FA) composition reflects dietary intake and endogenous turnover and is associated with health outcomes on a short and long term basis. The total plasma FA pool represents the composition of all FA containing lipid fractions.

Phthalate induced oxidative stress and DNA damage in earthworms (Eisenia fetida)

open access: yesEnvironment International, 2019
Phthalates (phthalic acid esters) have been widely applied as plasticizers. They are ubiquitous contaminants in soils, thereby posing a threat to human health.

Interactions of Plant Protein and Natural Colorant: A Structural and Functional Relationship of Broccoli Protein and Marigold Color Compounds

open access: yesFood Frontiers, Volume 7, Issue 4, July 2026.
Graphical representation of the interactions of the structural and functional relationships of broccoli flower protein (BFP) and marigold color compounds (MCC). This research examines BFP–MCC interactions of extracted marigold color, chemical composition, and functional attributes.
