A simulation method for ethylene glycol terephthalate polycondensation process.

Poly(ethylene terephthalate) Film Recycling

Screening Assay for Ethylene Glycol

To the Editor: The recent paper by Eder et al. (1) recalls, among other things, the problems that a clinical STAT laboratory has to face in the case of ethylene glycol poisoning. As an alternative to the precise and accurate gas chromatographic technique, the enzymatic assay with glycerol dehydrogenase (EC 1.1.1.6) and NADH as tracer has been proposed by various authors [see, e.g., (2–4)]. The ...

Simulation of Doxorubicin Delivery via Glucosamine(ethylene glycol) Carrier

This article focuses on the molecular modeling of the release of doxorubicin from capsules composed of glucosamine(ethylene glycol) oligomers. Doxorubicin forms micelle structures with glucosamine(ethylene glycol), and the drug release mechanism can be studied through the modeling of oligomeric bond breaking under acidic, neutral, or basic conditions. Under these conditions, the activation ener...

Fast screening of polycondensation catalyst, Determination of the kinetic data of catalyzed polycondensation in polyethylene terephthalate synthesis

Differential scanning calorimetry (DSC) belongs to the family of thermal analysis methods. In general thermal analysis is the determination of substance properties in dependence on temperature. Thermodynamic data (heat capacity, phase transition, enthalpy) and kinetic data can be determined by methods of thermal analysis. The greatest advantage of thermal analysis is the easy handling and the o...

Chemical Degradation of Poly(Ethylene Terephthalate)

The possibility of converting polyethylene terephthalate (PET) waste into terephthalic acid as a primary material by using different techniques through trans-esterification, with an alcohol and through hydrolysis in basic medium, has been investigated. In addition, utilization of activating agents such as inorganic salts and phase transfer catalysts has been investigated. Mineral water and beve...
