Precautions for the operation of p-tert-butyl phenol and p-tert-octylphenol
Notes for the operation of tert-butylphenol and tert-octylphenol: 1. Closed operation, enhance ventilation, use explosion-proof ventilation system and equipment; 2, the operator must first go through a period of special strict training, must ensure that everyone remember and always abide by the operating procedures; 3. Operators must wear good gas masks, protective glasses and protective clothing, wear rubber oil-resistant gloves and take good protective measures when working; 4. It is forbidden to open fire during work, keep the work area away from fire, and prohibit smoking in the workplace; 5. Production and packaging sites and transportation processes should be equipped with appropriate fire prevention and fire extinguishing equipment, as well as leakage emergency treatment equipment. If there is an accident such as a leak, it should be resolved quickly and the aftermath should be handled well.

P-tert-butylphenol is used as an antioxidant and stabilizer
The condensates of p-tert-butylphenol and barium sulfide, widely used as additives for oils and fats, are condensed with sulfur dichloride or sulfur monochloride to produce dialkylphenol sulfide and polyalkylphenol sulfide which can be used as corrosion inhibitors and antioxidants. This product is also used as rubber, soap, chlorinated hydrocarbons, nitrocelluloose stabilizer. And raw materials used as polyvinyl chloride stabilizers. The disubstitution of tert-butylphenol can be used in the production of antioxidant, textile flame retardant, preparation of pesticide emulsifier, etc. The application of p-tert-butyl phenol is very extensive, and more products can be developed through deep processing. At present, quite a number of products have been applied in industry, some of which are in urgent need of development and application. At present, pure phenolic resin with high softening point has been produced in China. Relevant research departments should immediately start to develop new technological formula of neoprene adhesives, so as to meet the needs of users as soon as possible and reverse the situation of imported adhesives.

Brief introduction to p-tert-butylphenol
P-tert-butyl phenol white crystal, flammable, with a slight phenol odor. Melting point 98-101℃, boiling point 236-238℃, 114℃ (1.33kPa), relative density 0.908 (80/4℃), refractive index 1.4787. Soluble in acetone, benzene, methanol, slightly soluble in water. Can evaporate with water vapor. Preparation of p-tert-butylphenol 1. It is prepared from phenol and isobutene with cation exchange resin as catalyst. 2. Prepared by reaction of phenol with diisobutene. In addition to tert-butylphenol, p-octylphenol is also produced in the reaction process. 3. The finished product was obtained by the reaction of phenol and tert-butanol after washing, crystallization, centrifugal separation and drying. Use of p-tert-butyl phenol 1. Used in oil soluble phenolic resin, and formaldehyde condensation can get a variety of applications 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.
