A novel and efficient strategy for the biodegradation of di (2-ethylhexyl) phthalate by

Abstract Di(2-ethylhexyl) phthalate (DEHP) is a plasticizer that is used worldwide and raises concerns because of its prevalence in the environment and potential toxicity. Herein, the capability of Fusarium culmorum to degrade a high concentration (3 g/L) of DEHP as the sole carbon and energy source in solid-state fermentation (SSF) was studied. Cultures grown on glucose were used as controls

production of phthalic anhydride from biorenewables: process design

Production of phthalic anhydride from biorenewables: process design

Its production is based on fossil feedstocks and is expected to grow up to 5 Mt per year by 2018, as such its market would be affected by petroleum depletion concerns. A renewable route to phthalic anhydride was found by Mahmoud et al. (2014) using biomass-derived furan (F) and maleic anhydride (MA).

Determination of phthalate acid esters plasticizers in polyethylene terephthalate bottles and its correlation with some

PET bottles are largely amorphous with a small degree of crystallinity (5¨C20%) [5]. Polymers with a high degree of crystallinity have a higher glass transition temperature Tg (Tg is 67 ¡ãC for amorphous PET and 81 ¡ãC for crystalline PET) and have higher toughness, tensile strength, hardness and more resistance to solvents, but less impact strength [ 6 ].

Thermal behavior of some cyclic anhydrides: an important characterization for synthesis in the polymer field

Polyfunctional cyclic organic anhydrides are widely used in different fields, especially in monomer synthesis and therefore polymers applications. However, there is a lack in the literature about their thermal and spectroscopic characterization, which can lead researchers to a misunderstanding result, interpretation, and even spoiling yield values when there is a mixture between anhydride and
