Synthesis of long-chain alkyl naphthalene base oil catalyzed by ionic liquids and its lubricating properties
摘要
Abstract
Alkyl naphthalene,an important aromatic lubricating base oil,offers excellent oxidation stability and compatibility properties.Traditionally,the alkylation reaction of naphthalene and olefins utilizes inorganic acids and solid acids as catalysts,but these methods are plagued by equipment corrosion and high reaction temperatures.The paper explores the alkylation of naphthalene with tetradecene to synthesize lubricating base oil,with acidic ionic liquids as catalysts.This study investigates the effects of ionic liquid composition,olefin to naphthalene ratio,reaction temperature,olefin droplet rate,and catalyst dosage on the reaction results.The ionic liquid composed of triethylamine hydrochloride and aluminum chloride proves beneficial for generating polyalkylation products.By adjusting the feed ratio of tetradecane and naphthalene,three samples with different side chain alkyl groups were successfully synthesized.Subsequently,the physicochemical and tribological properties of the synthesized base oils were tested and evaluated.According to the experimental results,alkyl naphthalenes with more alkyl groups on the side chain exhibit higher viscosity.Among the synthesized base oils,the sample with the feed ratio of 2 demonstrates superior viscosity index and suitable viscosity,offering advantages in reducing wear and enhancing anti-wear properties as a lubricating base oil.关键词
