A comprehensive guide to its molecular composition, solvent characteristics, and performance benchmarks.
Kocosol 200, also known globally under comparable trade names such as Solvesso 200 or Aromatic Solvent S200 (CAS No. 64742-94-5), is a high-boiling-point heavy aromatic hydrocarbon solvent fraction consisting predominantly of C10 to C13 aromatic hydrocarbons. Characterized by its high solvency power (Kauri-Butanol value typically exceeding 90) and high flash point, this heavy solvent is essential in applications where controlled evaporation, structural uniformity, and safety are critical.
Unlike light aromatic naphtha (such as S100 or S150), Kocosol 200 features a distinct distillation profile, typically boiling between 220°C and 300°C. This ensures low volatility under ambient temperatures, reducing volatile organic compound (VOC) emissions during processing, and making it highly suitable for temperature-sensitive thermal drying systems and industrial coatings.
For formulation scientists and procurement managers, choosing the correct heavy aromatic fraction is paramount. The table below represents the comparative chemical parameters of S200 (Kocosol 200 type) relative to lighter solvent profiles manufactured by Shandong Saier Chemical Technology Development Co., Ltd.
| Parameter / Product | Aromatic Solvent S100 | Aromatic Solvent S150ND | Kocosol 200 (S200 Class) |
|---|---|---|---|
| CAS Number | 64742-95-6 | 64742-94-5 | 64742-94-5 |
| Boiling Range (°C) | 160 – 180 | 182 – 208 | 220 – 290 |
| Flash Point (PMCC, °C) | > 42 | > 62 | > 93 |
| Kauri-Butanol (KB) Value | > 91 | > 95 | > 98 |
| Naphthalene Content (wt%) | < 0.1% | < 1.0% (ND Grade) | Standard < 8% / ND Grade < 1% |
| Aromatic Content (vol%) | > 99.0% | > 99.0% | > 99.0% |
Analyzing the practical application of Kocosol 200 across key target industries globally.
In localized farming regions globally, high-concentration Emulsifiable Concentrates (EC) and Oil-in-Water Emulsions (EW) rely on Kocosol 200. It dissolves complex, hydrophobic active ingredients such as triazoles, pyrethroids, and amide-based herbicides. Its high boiling point prevents crystallization on nozzle tips during warm weather applications, ensuring uniform crop protection.
For industrial OEM baking finishes, Kocosol 200 acts as a flow control agent and solvent carrier. Its slow evaporation profile promotes bubble-free surface leveling and a high-gloss finish. This is essential for continuous coil coating lines in manufacturing hubs across Europe and North America where defect rates must remain below 0.05%.
In mature oil field plays (such as the Permian Basin or Middle Eastern reserves), Kocosol 200 serves as a powerful carrier for corrosion inhibitors, drag reducers, and demulsifiers. Its high flash point reduces explosion risks on offshore platforms, while its solvent action effectively clears asphaltene deposits from production wells.
How Shandong Saier Chemical navigates environmental regulations and leads innovation in aromatic solvents.
As environmental legislation tightens globally—spearheaded by Europe’s REACH regulation and EPA clean air standards in the United States—the composition of aromatic solvents is facing scrutiny. Specifically, the concentration of Naphthalene (a naturally occurring polycyclic aromatic hydrocarbon present in heavy distillates) must be heavily restricted. Standard Kocosol 200 contains up to 8% naphthalene, which poses classification hazards under global GHS frameworks (H351: Suspected of causing cancer).
Shandong Saier Chemical’s engineering team has addressed this by establishing a dedicated refining roadmap for the mass production of Naphthalene Depleted (ND / Ultra-Low Naphthalene) variants. By employing continuous vacuum rectification and liquid-liquid extraction technologies, we can reduce the naphthalene content to less than 0.9% (and down to 0.1% for ultra-pure grades). This development allows our global partners to maintain excellent solvency without triggering strict hazardous warning labels on their end-use products.
