Chemische Eigenschaften
Perfluoroheptanoic acid is a white solid under ambient conditions, but it has a relatively low melting point (Huang, et al., 1987). In comparison, the C6 homologue, PFHxA, and other short-chain perfluorocarboxylic acids are volatile liquids (NICNAS, 2015a). The C8 homologue is also a solid under ambient conditions, although it has a relatively low sublimation temperature of 40°C (Kaiser, et al., 2010). Based on the properties of this long-chain homologue, solid PFHpA may sublime under ambient conditions.
Verwenden
Perfluorinated compounds (PFCs) have been detected in many environmental matrixes, biota, and nonoccupationally exposed populations in China recently. Being a persistent environmental pollutant, it ca n accumulate in human tissues via various exposure routes. PFHA may interfere in a toxic fashion on the immune system, liver, development, and endocrine systems.
Perfluoroheptanoate (PFHpA, perfluoroheptanoic acid, perfluoro-n-heptanoic acid, tridecafluoro-1-heptanoic acid) is a seven-carbon compound in the perfluoroalkyl family of chemicals. Perfluoroheptanoate is used in stain- and grease-proof coatings on furniture, carpet, and food packaging.
Perfluoroheptanoate is the seven-carbon chemical that is structurally similar to the highly persistent and outlawed PFOA. Much like other perfluoroalkyls, PFHpA can persist in the environment.
