The Application of Heavy Alkyl Benzene in Engine Oil and Hydraulic Fluid Formulations

Abstract

Heavy alkyl benzene (HAB) is a byproduct in the process of linear alkyl benzene (LAB) production. It is used as heat transfer oil and lubricating greases. In this article the potential of the usage of HAB in the formulation of gasoline and diesel engine oils as well as hydraulic fluid is indicated. With the aim of passing 5W30, 5W40, 10W40, and 15W40 standards, different engine oils have been formulated. The formulations contain various amounts of HAB as minor component, and miscellaneous quantities of solvent neutral 100 (SN-100), SN-150, and SN-650 as major component. The measurement of typical properties of obtained oils indicates that some of them do have the intended criteria. Test field of the recent oils designate that they have good performance. In the next step, different blends of HAB as major component and polyisobutene (PIB) as minor component have successfully been employed in the formulation of several ISO grade hydraulic fluids. The achieved materials do have suitable air release and demulsibility.

Applications of Mass Spectrometric Techniques to the Analysis of Fuels and Lubricants

“…One of the common classes of synthetic lubricant base stocks are the alkyl benzenes. These lubricants have found application in refrigeration systems and heavier alkylbenzenes have been used in automotive applications [42]. The GC-MS of these base stocks are characterized by series of peaks of the same molecular weight corresponding to different attachment points for the alkyl group.…”

Influence of FeCl3‐modified chloroaluminate ionic liquids on long‐chain alkenes alkylation

“…[1] The alkylation of long-chain alkenes with toluene to give long-chain alkyl benzene is an important raw material of the detergent and surfactant in tertiary oil recovery technology, which have attracted more attention. [2] Traditionally, various homogeneous catalysts have been used in this reaction, for instance, H 2 SO 4 , HF, and AlCl 3 , but their environmental nonfriendliness, troublesome product recovery and purification, and impossibility of catalyst recycling make them unsuitable for the purpose. [3][4][5] Therefore, many efforts have been made to exploit the environmentally friendly catalytic technology for the target reaction.…”

The study of industrializable ionic liquid catalysts for long‐chain alkenes Friedel–Crafts alkylation

“…Long-chain alkyl benzene is mainly used to produce surfactants in tertiary oil recovery technology, and has attracted more and more attention. [1,2] The current commercial catalysts for heavy alkyl benzene are concentrated hydrofluoric acid (HF) or solid acid. [3] Although these two catalysts show high catalytic activity and selectivity in the reaction, the processes have plenty of drawbacks, including equipment corrosion and high post-processing cost.…”
