Reaction of Terephthalic Acid with Ethylene Glycol.

The Glycolysis of Poly (ethylene terephthalate) Waste:Recovery of Terephthalic Acid by Magnetic FeO@APTS Nanoparticle

In this research, the chemical recycling of terephthalic acid from PET waste by using nano Fe3O4@Py-APTS as solid support was reported. The performance of organically modified nano magnetic was examined in detail and the results were compared with unsupported reactions as the model. By using the solid support, the required time for complete glycolysis, consumption of solvent and catalyst, decre...

Synthesis of terephthalic acid via Diels-Alder reactions with ethylene and oxidized variants of 5-hydroxymethylfurfural.

Terephthalic acid (PTA), a monomer in the synthesis of polyethylene terephthalate (PET), is obtained by the oxidation of petroleum-derived p-xylene. There is significant interest in the synthesis of renewable, biomass-derived PTA. Here, routes to PTA starting from oxidized products of 5-hydroxymethylfurfural (HMF) that can be produced from biomass are reported. These routes involve Diels-Alder ...

Successful Treatment of Ethylene Glycol Poisoning with Haemodialysis

Function of the classical and alternate pathways of human complement in serum treated with ethylene glycol tetraacetic acid and MgCl2-ethylene glycol tetraacetic acid.

An immunochemical and functional analysis of the classical and alternate complement pathways in human serum was performed in the presence of 10 mM ethylene glycol tetraacetic acid (EGTA) and MgCl(2)-EGTA (MgEGTA), chelating agents which have been recently utilized as a means of distinguishing between these two complement pathways. Total hemolytic activity, integrity of the C1 complex, hemolytic...

Reaction of ethylene oxide with nicotinamide and nicotinic acid.

It has been shown that treatment of animal diets with ethylene oxide results in severe destruction of thiamine, niacin, pyridoxine, riboflavin, and folic acid (2, 3) and of the essential amino acids, histidine, methionine (4)) and lysine (5). Consequently, studies were undertaken to elucidate the nature of the reactions of ethylene oxide with the above nutrients. The realization that a tertiary...
