Sodium Sulfonates

Sodium Sulfonate Manufacturer

Sonneborn’s sodium sulfonates are made from natural petroleum oil feedstocks. As a result, the distribution of molecular weights of our products is very broad, while the distribution of molecular weights of typical synthetic sodium sulfonates is narrow. The broad distribution of molecular weights of the Sonneborn Petronate sodium sulfonates enhances the ability of the sulfonates to interact with the oil and provides excellent emulsification compared to a synthetic sodium sulfonate of the same molecular weight. Sonneborn’s sodium sulfonates possess a structure which 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 Sonneborn sodium sulfonates improves their compatibility with the base oil. The resulting benefits are enhanced emulsion and rust prevention characteristics.

Sonneborn’s sodium sulfonates provide excellent emulsion quality and corrosion resistance. The low molecular weight sulfonates provide excellent emulsion performance, while the high molecular weight sulfonates provide an unsurpassed rust preventive coating. Depending on the application, the balance of these two properties is critical for performance in any market. In the oilfield, drilling and mining markets, which are less concerned with rust prevention, the strong emulsifier Petronate L is preferred. In the industrial oils market, where rust prevention is a large concern, the corrosion prevention of the Petronate H and Petronate HH are commonly specified in rust preventive oil. In the metalworking industry, a balance of both the emulsion and corrosion performances is critical to a successful formulation. Here the market prefers the balanced emulsion and corrosion resistance of Petronate HL.
