Introduction
Propyl gallate (PG)
Propyl gallate (PG), also known as propyl gallate, is a synthetic oil-soluble antioxidant. Oil-soluble antioxidants are all phenolic compounds, including butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT Chemicalbook), tert-butylhydroquinone (TBHQ), etc., which can provide hydrogen atoms to combine with free radicals produced by the auto-oxidation of oils and fats to form a relatively stable structure, blocking the chain auto-oxidation process of oils and fats, thereby achieving the purpose of anti-oxidation.
【Source】It is obtained by esterification of gallic acid and propanol at 120°C with sulfuric acid as catalyst. After neutralization, the solvent is distilled off and the residue is recrystallized from ethanol-water solution.
【Appearance】White to light beige powder.
【Chemical composition】Propyl Gallate(C10H12O5)
【Melting point】146-149℃
【Odor】Odorless
【Water solubility】0.35 g/100 mL (25℃)
