Maaskant, Evelien;van Es, Daan S. research published 《 Unexpected Susceptibility of Poly(ethylene furanoate) to UV Irradiation: A Warning Light for Furandicarboxylic Acid?》, the research content is summarized as follows. Poly(ethylene furanoate) (PEF) is widely advocated as renewable alternative to the fossil-based polyester poly(ethylene terephthalate) (PET). Whereas the UV-stability of PET is well-studied, little is known for PEF. Here, we compare the UV-stability of both polyesters after 500 h of UV-irradiation in a Q-SUN xenon arc chamber. Both the virgin and irradiated polyesters were characterized by FTIR, SEC, DSC, NMR, TGA, and MALDI-TOF MS. PET showed only minor signs of degradation under the applied test conditions, while PEF showed significant discoloration, as well as evidence of both crosslinking/chain extension and chain scission. Also the thermal properties and the ability to crystallize of PEF were severely impacted by UV-irradiation Although a detailed study on the degradation mechanism is out of scope for this work, we found indications that Norrish type I and II degradation reactions play an important role in the UV-degradation of PEF.
611-13-2, Methyl 2-furoate has been identified as one of the volatile flavor compounds in tequila, okra, berrycactus and black currant juice.
Methyl 2-furoate, also known as fema 2703 or methyl pyromucate, belongs to the class of organic compounds known as furoic acid esters. These are ester derivatives of furoic acid. Methyl 2-furoate is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Within the cell, methyl 2-furoate is primarily located in the cytoplasm. Methyl 2-furoate is a sweet, fruity, and fungal tasting compound that can be found in a number of food items such as cocoa and cocoa products, potato, tamarind, and fruits. This makes methyl 2-furoate a potential biomarker for the consumption of these food products.
Methyl 2-furoate is a reactive compound that belongs to the family of sesquiterpene lactones. It has been shown to have phosphotungstic acid and hydrochloric acid reactivity, as well as nitrous and water vapor sensitivity. Methyl 2-furoate also reacts with radiation, which can be used for structural analysis. The compound is an intermediate in the synthesis of pluronic p123, which is used in fabricating biomedical devices. Methyl 2-furoate has been shown to have anti-inflammatory properties through its inhibitory effect on prostaglandin synthesis., Application of C6H6O3
