An in-depth analysis of chemical properties, high solvency performance, regulatory compliance, and manufacturer supply dynamics.
In the global specialty chemical sector, high-performance solvents play a critical role as carriers and diluents. Solvesso 200 Nd (Naphthalene-Depleted) represents a pinnacle in heavy aromatic solvent formulation. It combines high solvency power, elevated flash points, and low volatility with strict ecological compliance. This technical whitepaper explores the physical-chemical properties, macroeconomic applications, manufacturing protocols, and compliance frameworks that make Solvesso 200 Nd indispensable to modern industrial systems.
Historically, heavy aromatic solvents like standard S-200 contained up to 10% naphthalene. Naphthalene is a volatile bicyclic aromatic hydrocarbon classified under modern environmental systems as a suspected carcinogen and an acute aquatic hazard. Global environmental protection agencies, including the US EPA and EU REACH, have enacted strict limits on chemical exposures. Consequently, global chemical users have shifted to Naphthalene-Depleted (ND) aromatic solvents. Solvesso 200 Nd meets these standards by reducing naphthalene content to less than 0.9 wt% (and typically below 0.1 wt%), preserving high-boiling C10-C12 aromatic isomer compositions.
Did you know? Naphthalene depletion is achieved through advanced multi-stage vacuum fractional distillation columns. This process removes the narrow-boiling fraction containing naphthalene while retaining the high-boiling alkylbenzene homologues. These homologues are crucial for maintaining a high Kauri-Butanol (KB) solvency value.
Solvesso 200 Nd is comprised mainly of C10 to C12 alkylbenzenes, characterized by a narrow distillation range, high flash point, and superior solvency. The table below highlights the physical and chemical characteristics of this high-boiling aromatic hydrocarbon solvent.
| Property Parameter | Typical Value Range | Test Standard Method | Industrial Importance / Significance |
|---|---|---|---|
| CAS Number | 64742-94-5 | Chemical Abstracts | Universal classification for Heavy Aromatic Naphtha. |
| Aromatic Content | ≥ 99.0 vol % | ASTM D1319 | Ensures high solvency power for active ingredients & resins. |
| Naphthalene Content | < 0.9 wt % (Typically < 0.1 wt %) | GC-MS Analysis | Exempts products from Carcinogen Category 2 labeling requirements. |
| Initial Boiling Point (IBP) | 230 °C - 240 °C | ASTM D86 | Low volatility ensures stability in high-temperature curing. |
| Dry Point | 285 °C - 295 °C | ASTM D86 | Guarantees complete, uniform evaporation without leaving residues. |
| Flash Point (Pensky-Martens) | ≥ 100 °C | ASTM D93 | Improves industrial warehouse safety; non-flammable classification. |
| Aniline Point | ≤ 15 °C | ASTM D611 | Low aniline point indicates high aromaticity and solvency. |
| Density at 15 °C | 0.990 - 1.010 g/cm³ | ASTM D4052 | Facilitates precise formulation calculations and blending. |
| Kauri-Butanol (KB) Value | ≥ 95 | ASTM D1133 | Quantifies superior capacity to dissolve heavy resins and polymers. |
This distinct property profile makes Solvesso 200 Nd an effective alternative to traditional chlorinated solvents or low-boiling ketones. Its high flash point minimizes vapor combustion hazards in industrial settings, while its low evaporation rate supports uniform curing in baking finishes and ensures long-term stability in agricultural emulsions.
How global enterprises deploy Solvesso 200 Nd across specialized chemical sectors to achieve product stability, high dissolution, and safety compliance.
Solvesso 200 Nd serves as a primary carrier solvent for Emulsifiable Concentrates (EC), Oil Dispersions (OD), and Suspoemulsions (SE).
Widely utilized in coil coatings, automotive OEM finishes, protective container coatings, and high-temperature enamels.
Crucial for formulating high-performance chemical blends used in deep-well oil and gas extraction processes.
Founded in December 2004 and headquartered in Zibo City, Shandong Province, Shandong Saier Chemical Technology Development Co., Ltd. is located in the Qilu Chemical Industrial Park (No. 207, WeiLiu Road, Linzi). With a registered capital of 60 million yuan, we have built a robust financial foundation and a state-of-the-art refining infrastructure.
Originally focused on basic petrochemical fractions, we optimized our operations to meet the demand for high-purity, environmentally friendly chemical intermediates. Today, our annual production capacity reaches 720,000 tons per year. We supply both domestic markets (Beijing, Shanghai, Tianjin, Hebei, Shandong, Henan) and global markets across Asia, Europe, the Americas, and Southeast Asia.
We source our raw material feedstocks from major domestic refiners, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. This stable raw material supply ensures consistent quality for our entire high-boiling aromatic solvent range.
Shandong Saier Chemical has implemented a Factory 4.0 paradigm, integrating Distributed Control Systems (DCS) and safety-instrumented systems to ensure reliable high-volume chemical processing. Our industrial complex features dedicated fractionators, large-scale storage tank farms, and automated loading bays that run continuously to prevent supply chain bottlenecks.
As a national high-tech enterprise, we invest in process optimization. Our production processes minimize carbon intensity and energy consumption per ton of solvent produced. Close proximity to local shipping lanes and major Chinese ports enables efficient logistics and reliable international delivery timelines.

Supply Chain Security Note: Our raw material pipeline is directly linked to major regional refineries. This structural advantage insulates our production schedule from feedstock shortages, allowing us to maintain stable pricing and delivery lead times for international contracts.
The heavy aromatic solvent market is evolving to meet higher purity standards and lower emissions limits. Our R&D division focuses on three main development goals:
While the standard ND classification requires naphthalene levels below 0.9 wt%, our current production consistently achieves <0.1 wt%, and we are working toward sub-50 ppm levels. This supports compliance with strict occupational health guidelines and enables our customers to register hazard-free formulations globally.
We are researching the integration of renewable, plant-derived esters with high-boiling aromatics to create hybrid carriers. These hybrids maintain the high solvency of aromatics while improving the biodegradability index of agricultural spray adjuvants.
By upgrading our distillation systems with thermal vapor recompression (MVR) technologies, we target a 20% reduction in thermal energy consumption. This aligns our solvent supply chain with international carbon-reduction goals.
Exporting chemical compounds globally requires strict adherence to regional regulatory frameworks. Shandong Saier Chemical provides full compliance support for shipments of Solvesso 200 Nd to international destinations:
We provide full REACH compliance documentation and work with Only Representative (OR) structures. This ensures smooth customs clearance and regulatory compliance within the European Economic Area.

Complementing our high-boiling Solvesso 200 Nd series, Shandong Saier Chemical manufactures and exports Aromatic Solvent S100 (CAS No. 64742-95-6). S100 is produced using crude C9-C10 aromatics via a continuous rectification process.
It is a colorless, transparent, organic solvent with a pleasant aromatic odor. S100 is widely used in applications that require a lower boiling range (typically 160°C - 180°C) and faster evaporation than the S200 series. This makes it an ideal option for paint formulations, thinner packages, and fast-dry agricultural emulsifiable concentrates.
