Reaction Network and Kinetics Model for Neutral Hydrolysis of Poly(ethylene terephthalate).
Article in Industrial & engineering chemistry research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We present a reaction network and kinetic model that describes the hydrolytic depolymerization of poly-(ethylene terephthalate) (PET) in water with neutral pH. The network comprises seven reaction pathways. It includes autocatalysis of PET depolymerization by terephthalic acid (TPA) and the generation of monohydroxyethyl terephthalate, bis-(2-hydroxyethyl) terephthalate, benzoic acid, and decomposition products of TPA and ethylene glycol as byproducts. The model can handle PET hydrolysis in the solid state and in the molten state. Parameter estimation was performed by fitting the model to product concentrations from literature for PET hydrolysis over a wide range of times (15 s to 25 h) and nominal reaction temperatures (170-570 °C). The model fits the entire set of experimental concentrations with a mean absolute error of 0.023 M. It also demonstrated the ability to predict product yields from many published studies. The highest TPA yield predicted by the model is 94%, obtained from hydrolysis at 450 °C (instantaneous heating) after a 20 s batch holding time. TPA yields of 100% were not achievable in the model because of TPA decomposition pathways and equilibrium reactions involving byproducts.
