Stability Chemical property [CAS login number] 140-66-9 【EINECS entry number 】205-246-2 Molecular weight: 206.32 【 Molecular Formula and Structural formula 】 The molecular formula is C14H22O, and the chemical formula is as follows: Common chemical reaction with benzene ring substitution reaction and hydroxyl reaction properties. [Forbidden compound] strong oxidant, acid, anhydride. [Polymerization hazard] No polymerization hazard Main use P-teroctyl phenol is a raw material and intermediate of fine chemical industry, such as the synthesis of octyl phenol formaldehyde resin, widely used in oil additives, ink, cable insulation materials, printing ink, paint, adhesive, light stabilizer and other production fields. Synthesis of non – ionic surfactant, widely used in detergent, pesticide emulsifier, textile dye and other products. Synthetic rubber auxiliaries are indispensable for the production of radial tires. Toxicity and environmental effects P-teroctyphenol is a toxic chemical that is irritating and corrosive to the eyes, skin and mucous membranes and can cause blurred vision, congestion, pain and burning. Large amounts of inhalation can cause coughing, pulmonary edema, and difficulty breathing. Frequent contact with skin can cause skin bleaching. Moderate irritation: Rabbit eye meridian: 50μg/ 24h. Moderate stimulation: 20mg/24 hours percutaneous in rabbits. Acute poisoning rats transoral LD502160mg/kg.

Application and development of p-tert-butylphenol
(1) Preparation of oil-soluble phenolic resin 1. Active phenolic resin P-tert-butylphenol and formaldehyde were condensed under the action of sexual catalyst to produce p-tert-butylphenol formaldehyde resin. The products are used to prepare neoprene adhesive, rubber vulcanizing agent, coating, oil, enamelled wire and other fine chemical products. 2. Inactive pure phenolic resin Using acid as catalyst, the condensation of tert-butylphenol and formaldehyde was used to produce inactive pure phenolic resin. The resin is specially used for the preparation of neoprene adhesive. 3. Using cation exchange resin as catalyst, the inactive pure phenolic resin was prepared, which was specially used for preparing chloroprene adhesive. Whether active or inactive resin, the meltable phenolic resin can be obtained by adding 10~15% of this product into the chloroprene adhesive. Chloroprene adhesive is mainly used in transportation, construction, civil shoes, etc. It can also be used for the preparation of rosin modification, offset printing, advanced photogravure, etc., as well as the production of coil dip varnish and laminate varnish. (2) Preparation of spices 1. Tert-butylcyclohexyl acetate 2.4- tert-butyl-1,1 dioxethylcyclohexane is used as raw material for catalytic dehydrogenation to produce tert-butylcyclohexanone, and then hydrogenated with ethylene glycol ester to become tert-butylcyclohexanol, and then acetylated to produce tert-butylcyclohexanol acetate, commonly known as violet ester, with woody aroma, can be well scented with violet one. Tert-butylphenol cyclohexanone has a strong camphor taste, used in soap, detergent aroma. (3) Used as 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. (4) Used as the reaction termination agent of phosgene polycarbonate process: the addition amount is 1.0~3.0% of resin (5) Other applications Used for epoxy resin modification, xylene resin modification, condensation the product is widely used in preparation of daily chemical essential oil and soap, detergent flavor. 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.
