Carbolic Acid (Phenol) (C6H5OH, CAS 108-95-2) is a colorless to pink crystalline solid that melts at about 106°F (41°C), so it is shipped molten or as liquefied phenol (about 90% with water). It is toxic and is rapidly absorbed through the skin. Phenol is used to make bisphenol A, phenolic resins, caprolactam for nylon, alkylphenols and disinfectants. Phenol storage often requires heated, insulated tanks; check the temperature limits of each resin. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
PVDF (Kynar®) is the most economical tank material for Carbolic Acid (Phenol), rated Excellent. Polypropylene is also rated Good or better. Avoid HDPE and nylon tanks; HDPE and PVC fittings; Buna-N gaskets.
