p-tert-octylphenol (PTOP) CAS No. 140-66-9
Product description of p-octylphenol
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), PTBP for short.
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 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.

Main use
1. Used for oil soluble phenolic resin, and formaldehyde condensation can get a variety of products. In the chloroprene adhesive mixed 10-15% of the product, to obtain soluble resin, this kind of adhesive is mainly used in transportation, construction, civil, shoe-making, etc. In printing ink, can be used for rosin modification, offset printing, advanced photogravure and so on. In the insulation varnish, can be used in coil dip varnish and laminate varnish.
2. Used for polycarbonate production, as phosgene polycarbonate reaction termination agent, adding amount of 1-3% of resin.
3. Used for epoxy resin, xylene resin modification; As polyvinyl chloride stabilizer, surfactant, UV absorber.
4. It has antioxidant properties and can be used as a stabilizer for rubber, soap, chlorinated hydrocarbons and nitrocelluloses. It is also a raw material of insect repellent (medicine), acaricide acaride (pesticide) and plant protection agent, fragrance, synthetic resin, and can also be used as softener, solvent, dye and paint additive. It can also be used as the ingredient of demulsifier for oil field and additive for vehicle oil.
