P-tert-butylphenol has antioxidant properties and can be used as a stabilizer for rubber, soap, chlorinated hydrocarbons and digestive fibers. Uv absorbent, pesticide, rubber, paint and other anti cracking agent. For example, used for polycarbon resin, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, styrene stabilizer. In addition, it is also the raw material of pharmaceutical insect repellent, pesticide and acaricide, fragrance and plant protection agent. It can also be used as softener, solvent, additive of dyes and paints, antioxidant of lubricating oil, oil demulsifier and additive of vehicle fuel.
Other applications:
(1) For oil soluble phenolic resin, the product and formaldehyde condensation can be obtained for a variety of purposes. 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) For polycarbonate production, as phosgene polycarbonate reaction termination agent, adding Chemicalbook amount of 1-3% of the resin.
(3) Used for epoxy resin, xylene resin modification; As polyvinyl chloride stabilizer, surfactant, UV absorber.
(4) With antioxidant properties, can be used as rubber, soap, chlorinated hydrocarbons and nitrocelluloose stabilizer. 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.
