“…High oxidation and thermal stability (Nicholos and Smith, 1970;Gschwender et al, 1990;Igarashi et al, 1992a, b), high hydrolytic stability (Hourani et al, 2007), good solvency (Willschke et al, 1988;Sowle and Lachocki, 1966;Hourani et al, 2007), desirable blend properties (Leand and Shim, 1997), low volatility (Willschke et al, 1988;Sowle and Lachocki, 1966), and excellent pour points (Rudnick, 2006), are the general advantages of alkylated benzens and naphtalenes. The higher cost is the main advantage of the oil.…”

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.

SYNOPSISPolyolefinic oils obtained from olefin oligomerization or copolymerization involve the most common synthetic hydrocarbon oils. Research and experimental results concerning high viscosity index synthetic polyolefinic oils and viscosity index improvers' production by ethylene-propylene copolymer (EPR) and thermal destruction of EPRs noted for various molecular weight and composition resulted in high viscosity index polyolefinic oils and thickeners. The effect of structure, composition, and molecular weight on the destruction process has been discussed for various EPRs. The resulting polyolefinic oils and viscosity index improvers were studied. 0 1992 John Wiley & Sons, Inc. I NTRODUCTIO NWhen petroleum oils cannot meet the increasing demands upon modern motor oils, synthetic and semisynthetic oils may be used.'-3 The application of these oils is intended for the producing of allweather oils with extremely low volatility, which contributes to lowering of oil consumption approximately by a factor of two. ' Usually, motor oil bases are prepared from polyolefin and ester mixtures.' The composition of polyolefin oils is similar to that of high-purity paraffin oils. The length of the main carbon chain and the side-chain position provide good viscosity and temperature characteristics. High thermostability and low volatility are inherent in polyolefin oils. Commercial oils of a such basis correspond to the oil classification of I S 0 VG and range from 5 to Polyolefinic oils are usually obtained by polymerization of high molecular olefins with the number of carbon atoms of C8-Cl0. The production of polyolefinic oils based on petroleum gases (ethylene and propylene ) is extremely promising, because the lack of petroleum raw material makes them the only source of providing industry with lubricant mate-1000.~ * To whom correspondence should be addressed. EXPERIMENTALEthylene-propylene copolymer was synthesized over Ziegler-Natta organometallic catalytic systems in liquid propylene as the Production of additives and lubricating oils on its basis was discussed in Refs. 6-8. In ethylene-propylene copolymer synthesis the following systems were used vanadium triacetyl acetonate + diisobutyl aluminum chloride [ (ACAC)~V + Al( iC4H9)&1] and vanadyl trichloride + diethyl aluminum chloride [V0Cl3 + A1 (C,H,),Cl]. High-purity ethylene and propylene (99.0 and 99.6 vol %, respectively) were used as reactants.The copolymerization process was carried out in a 7 L bench-scale batch reactor and in a continuous pilot plant with a capacity of 20 kg/ h. The copolymer samples thus obtained contained from 25 to 60 mol % of propylene units and exhibited elastomeric properties and viscosity-average molecular weight ( M u ) of 30,000-500,000. Thermal destruction of EPR was carried out in a 1.5 L bench-scale glandless batch autoclave equipped with an electric heater, a stirrer, and a temperature and residual pressure controller.The autoclave was charged with 0.7 kg of lump polymer and heated a t a rate of 3-5"C/min.
