Petroleum sulfonate, calcium salt

Sulfonates for Lube Additives. Most petroleum sulfonates used as lube additives are based on calcium or magnesium salts. These salts can be produced by direct neutralization of the sulfonic acid with Ca(OH)2 or Mg(OH)2, or by use of a metathesis process involving the sodium salt ... 

High-performance liquid chromatography is performed using a Hewlett-Packard 1090 chromatograph equipped with a ternary-solvent delivery system, an autoinjector with a 0 -20- u.L injection loop, an oven compartment, and a diode-array UV detector. An ELS detector (Alltech Associates, Deerfield, IL) is connected in series to the UV detector. Hexane, 2-propanol, and water were used for the analysis of nonionic surfactants. Water and tetrahydrofuran (THF) are used for the analysis of anionic surfactants. No preliminary sample preparation is used other than dilution. The nonionic surfactants are diluted 1 40 (v/v) with hexane. The anionic surfactants (alkyl ether sulfates and synthetic and petroleum sulfonates) are diluted 1 20 (v/v) with water-THF (50 50). The calcium sulfonate surfactants were diluted 1 20 (v/v) with a THF-38% hydrochloric acid solution of pH 1. Hydrochloric add is required to prevent salt precipitation by converting any excess water-insoluble caldum carbonate into water-soluble calcium chloride. All diluted samples are...

Antioxidant additives to alleviate oxidation, sludging, or corrosion are extensively used. An enormous number of agents have been recommended or used and a few are calcium petroleum sulfonates, sulfurized terpenes or olefins, metal salts of phenol sulfides, phosphorus pentoxide-treated terpenes, and zinc methylcyclohexylthiophosphate. Antifoaming agents such as silicone compounds when used in minute amounts effectively reduce the tendency to foam.

Petroleum sulfonates are oil-soluble compounds that find use as emulsifiers in lubricating oil and other functional fluids and in secondary oil recovery. They are usually supplied as sodium salts in mixtures with oil. They may contain unsulfonated oil or be diluted in a light petroleum distillate. Overbased products contain high alkalinity additives, such as colloidal calcium carbonate.
