Usage

Uses

Used in Plastics and Rubber Industry:
2,5-Bis(1-methylpropyl)phenol is used as an antioxidant and stabilizer for enhancing the durability and stability of plastics and rubber products. It prevents the degradation of these materials when exposed to oxygen and heat, thereby extending their shelf life and performance.
Used in Fuel Industry:
In the production of gasoline and jet fuels, 2,5-Bis(1-methylpropyl)phenol is used as a stabilizer to prevent the oxidation and degradation of fuels during storage and use, ensuring their quality and performance.
Used in Personal Care Products:
2,5-Bis(1-methylpropyl)phenol is used as a preservative in lotions and soaps to prevent spoilage and extend their shelf life. Its ability to inhibit the growth of microorganisms helps maintain the product's integrity and effectiveness.
However, it is important to handle 2,5-Bis(1-methylpropyl)phenol with care, as prolonged exposure can cause skin and eye irritation, and it may be harmful if ingested or inhaled. Proper safety measures should be taken during its use and disposal to minimize potential health risks.

Method for preparing hydrocarbyl phenol by catalytic conversion of phenolic compound in presence of molybdenum-based catalyst

The invention discloses a method for preparing hydrocarbyl phenol by catalytic conversion of a phenolic compound in the presence of a molybdenum-based catalyst. The method comprises mixing a phenoliccompound, a molybdenum-based catalyst and a reaction solvent, adding the mixture into a sealed reactor, feeding gas into the reactor, heating the mixture to 150-350 DEG C, carrying out stirring for areaction for 0.5-2h, then filtering to remove a solid catalyst and carrying out rotary evaporateion to obtain a liquid product. The phenolic compound has a wide source, a cost is low, product alkyl phenol selectivity is high, an added value is high, alcohol or an alcohol-water mixture is used as a reaction solvent, environmental friendliness is realized, pollution is avoided, any inorganic acids and alkalis are avoided in the reaction process, the common environmental pollution problems in the biomass processing technology are solved, the reaction conditions are mild, the process can be carried out at a low temperature, high-efficiency conversion of the reactants can be realized without consuming hydrogen gas and the method is suitable for large-scale industrial trial production.

Equilibria for the isomerization of (secondary-alkyl)phenols and cyclohexylphenols

Equilibria of a series of isomerizations and trans-alkylations of alkylphenols have been investigated in the liquid phase over a wide range of temperatures.Equilibria of isomerizations connected with the displacement of a substituent on a benzene nucleus were studied for secondary-butyl, -amyl, -hexyl, and cyclohexyl-phenols, and di-(secondary-butyl)phenols.Equilibria of positional isomerization connected with the displacement of an oxyphenyl radical in an alkyl chain were investigated for oxyphenyl-pentanes, -hexanes, -octanes, and -decanes.Trans-alkylation was investigated for di- and tri-(secondary-butyl)phenols.Values of ΔrH0m and ΔrS0m were found for all investigated reactions.An analysis was made of the thermodynamic quantities for the reactions.Enthalpies of formation of isopropylphenols (IPP) in the gaseous state were calculated.The values of ΔfH0m/(kJ * mol-1) were found at 298.15 K: o-IPP, -(175.3 +/- 2.4); p-IPP, -(175.3 +/- 2.4); m-IPP, -(175.3 +/-2.4); 2,4-di-IPP, -(254.1 +/- 2.8); 2,5-di-IPP, -(254.1 +/- 2.8); 2,6-di-IPP, -(254.1 +/- 2.8); 3,5-di-IPP, -(254.1 +/- 2.8); 2,4,6-tri-IPP, -(333.0 +/- 3.1).
