Natural sodium sulfonates
Natural sodium sulfonates are the key raw material of many metalworking fluid formulations and are available in a range of molecular weights. The broad distribution of molecular weights of the DBM natural sodium sulfonates enhances the ability of the sulfonate to interact with the oil and provides excellent emulsification compared to a synthetic sodium sulfonate of the same molecular weight.
DBM natural sodium sulfonates possess a structure that is composed of a poly-alkylated aromatic ring system, where the alkylates are primarily branched and short-chained. The typical synthetic sodium sulfonates are mono-alkylated aromatic ring systems where the alkylates are linear and long-chained. The presence of these short-chained and branched alkyl aromatic groups in DBM natural sodium sulfonates improves their compatibility with the base oil. The resulting benefits are enhanced emulsion and rust preventive coating characteristics.
Applications
Outside of metalworking, for motor oil and fuel additives, natural sodium sulphonates are often converted to calcium or barium salts. When used as an additive in motor oils, detergency and rust-inhibitive properties are the most important functions. Other common uses include emulsifiers and corrosion inhibitors in degreasers, wetting agents, rust preventatives, ore flotation, and detergents. Sulphonates with a higher molecular weight are highly effective corrosion inhibitors, particularly when based on the non-water-soluble cations of calcium, barium, and magnesium.
