Abstract: A process for fixing elemental mercury (Hg.degree.) in a spent molecular sieve desiccant is disclosed. The process includes isolating gspent molecular sieve desiccant containing elemental mercury, and contacting the spent desiccant in a dilute aqueous solution of an alkaline metal salt. The reaction traps the mercury within the spent desiccant as an insoluble heavy metal salt. The alkaline metal salt can include, for example, sodium thiosulfate (Na.sub.2 S.sub.2 O.sub.3), sodium polysulfide (Na.sub.2 S.sub.x), or potassium peroxomonosulfate (KHSO.sub.5). The reaction with any of these aqueous solutions acts to fix the elemental mercury (Hg.degree.) as a mercury compound within the solid desiccant. If sodium thiosulfate or sodium polysulfide is utilized, then the process also includes introducing hydrochloric acid (HCl) in a suitable quantity to liberate sufficient elemental sulfur to react with the elemental mercury (Hg.degree.) to form an HgS salt. The formation of HgS fixes the elemental mercury (Hg.degree.

Abstract: Alkylated aromatic functional fluids are prepared by alkylating a light cycle oil with an alkylating agent, such as an alpha C.sub.14 -olefin or coker gas oil, over a crystalline metallosiicate catalyst, preferably an aluminosilicate, including MCM-22, USY or an acid treated kaolin clay. The process produces an improved light cycle oil in which the heteroatom content of the oil is reduced and a high quality synthetic alkylated aromatic functional fluid base stock boiling above 600.degree. F. The reactor temperature can be elevated to increase the functional fluid yield and the extent of heteroatom removal.

Abstract: It is disclosed that aromatic compounds can be alkylated with mono-olefinic HVI-PAO dimer in contact with an acidic catalyst to produce novel alkylated aromatic compositions. It has been found that the novel HVI-PAO dimer alkylated aromatic compositions exhibit an extraordinary combination of properties relating to low viscosity with high viscosity index and low pour point which renders them very useful as lubricant basestock. Further, it has been found that the novel alkylaromatic compositions of the present invention show improved oxidative stability. Depending upon the substituent groups on the aromatic nucleus, useful lubricant additives can be prepared for improved antiwear, antioxidant and other properties. HVI-PAO dimer is prepared as a product or by-product from 1-alkene oligomerization using reduced chromium oxide on solid support.

Abstract: A method for detecting mercury amalgamation of an aluminum body includes the steps of contacting a surface of the aluminum body with an electrolyte, and simultaneously contacting the electrolyte with a reference electrode. The reference electrode is formed of a metal which is more electronegative than the aluminum body being tested, such that the electrolyte creates an electrochemical cell between the aluminum and the reference electrode, which cell produces an electromotive potential between the aluminum and the reference electrode. The potential difference is monitored. The potential difference will differ when the aluminum surface contacted with the electrolyte is mercury amalgamated from when no mercury amalgamation is present in the aluminum surface contacted.

Abstract: The invention is directed to method of making a thermally and oxidatively stable lubricating oil having a high viscosity index and a low pour point by the thermal polymerization of 1-olefins containing 8 to 10 carbon atoms, the preferred 1-olefins are 1-decanes. The polymerization is conducted at temperatures ranging from 280.degree. C. to 350.degree. C. and low pressures, of less than about 280 psig, in a reactor which is free of catalytic material. Thereafter, the polyalphaolefin is hydrotreated over a nickel catalyst, preferably nickel on Kieselguhr. In an improved process the polyalphaolefin is separated from a low molecular weight product by distillation. The low molecular product contains unreacted 1-olefins which are recycled to the thermal polymerization zone to produce more of the lubricant base stock.

Abstract: A lubricant contains an antioxidant and antiwear amount of a Mannich base reaction product of a phenylenediamine, such as N,N'-dihydrocarbyl substituted phenylenediamine, an aldehyde or ketone and a dialkyl-substituted phosphonate such as dimethyl hydrogen phosphonate or bis(2-ethylhexyl) hydrogen phosphonate.

Abstract: A process is disclosed that provides a high conversion of n-butane to C.sub.5 + gasoline by integrating the medium pore metallosilicate catalyzed process for fresh n-butane conversion to C.sub.5 + gasoline with a medium pore metallosilicate catalyzed process for propane conversion in a manner which allows a portion of the propane by-product of n-butane conversion to be converted to C.sub.4 + alkanes, followed by recycle of the n-butane portion of the C.sub.4 + alkanes. It has been discovered that separation of the products from the separate propane and n-butane conversion steps can be carried out concurrently in a single fractionator to provide the C.sub.5 + gasoline product and the propane and butane recycle streams. Preferably, the fractionator butane cut is treated in a deisobutanizer to recover isobutane and n-butane recycle. A further discovery utilizes the common fractionator not only to separate the products from the conversion processes but to concurrently separate a mixed fresh C.sub.3 -C.sub.

The preferred dialkyl metal sulfosuccinate is dioctyl-sodium sulfosuccinate. The Preferred metal hydrocarbylsulfonate is calcium dinonylnaphthalenesulfonate which is added to impart age and heat stability to the product. The overbased metal phenate sulfides are suitable as lubricant and functional fluid additives.
