P-tert-butyl phenol (PTBP) CAS No. 98-54-4
p-tert-Butylphenol (English name P-tert-Butylphenol, 4-t-Butylphenol) also known as 4-tert-Butylphenol (4-tert-Butylphenol), 1-Hydroxy-4-tert-butylbenzene (1-hydroxy - 4-tert-Butylbenzene), 4-(1,1, Dimethylethyl)phenol (4-(1, 1-dimethylethyl)phenol), abbreviated as PTBP. P-tert-butyl phenol is white or white flake solid at room temperature, with special alkyl phenol odor. It burns in an open flame. Flammable but not flammable, decomposition by heat gives off toxic gases. Soluble in alcohols, esters, alkanes, aromatic hydrocarbons and other organic solvents, such as ethanol, acetone, butyl acetate, gasoline, toluene, etc. Slightly soluble in water, soluble in strong alkali solution. This product has the common characteristics of phenolic substances, in contact with light, heat, contact with air, color gradually deepened. This product is toxic and moderately irritating to skin, mucous membrane and eyes. Toxic to aquatic organisms and may have long term adverse effects on the water environment. The main purpose is to synthesize p-tert-butyl phenolic resin. It can also be used as an inhibitor and stabilizer. The molecular formula is C10H14O.
