Whitepaper: Industrial Scope and Utility of Arosol 200 (Aromatic Solvent S200)

In modern industrial chemistry, heavy aromatic solvents occupy a critical role as structural formulation bases. Arosol 200, widely recognized under the industrial classification of Aromatic Solvent S200 (CAS No. 64742-94-5), is a high-performance hydrocarbon mixture dominated by C10-C13 aromatic compounds. It stands out in complex chemical applications due to its high boiling point range, low volatility, exceptionally high solvency power, and elevated flash points, making it a reliable carrier system in agricultural, coating, and cleaning applications.

This industry report acts as a definitive procurement guide for commercial buyers seeking to establish reliable manufacturer relationships in China. By analyzing the engineering parameters of Arosol 200, its local supply chain infrastructure within key economic zones, environmental safety configurations (including low-naphthalene standards), and global logistics pathways, we provide searchers with high-level technical accuracy and practical insights.

Critical Regulatory Designation: CAS 64742-94-5

Arosol 200 falls under the classification of Solvent Naphtha (petroleum), heavy aromatic. This category contains hydrocarbon blends consisting primarily of aromatic hydrocarbons having carbon numbers predominantly in the range of C10 through C13 and boiling in the range of approximately 230°C to 290°C (446°F to 554°F). Under global harmonization standards, it is recognized for high-performance solvating stability.

Chemical Specification Matrix: Arosol 200 vs. S150

Understanding the exact physical-chemical characteristics of heavy aromatic solvents is necessary to ensure the formulation stability of agricultural emulsifiable concentrates (EC), specialized industrial coatings, and oilfield surfactant packages. The table below represents standard operational tolerances for high-purity S200 batches compared alongside its counterpart, S150.

Localization Support & Global Regulatory Compliance

Distributing bulk chemical solvents globally requires strict adherence to international safety policies and chemical registration frameworks. Shandong Saier Chemical provides full-spectrum regulatory integration to support smooth import processes across various regions:

REACH Registration Compliance: For chemical buyers in the European Union, we supply REACH-compliant registration data and safety sheets. Our low-naphthalene variants of Arosol 200 align with strict European chemical restrictions.
GHS Classification and SDS Documentation: Every shipment is accompanied by custom multi-lingual Safety Data Sheets (SDS) formulated in compliance with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
ISO 9001:2015 & ISO 14001:2015 Certification: Our manufacturing facility maintains active management systems verifying strict process control, emissions handling, and raw material utilization efficiency.
Custom Packaging Configurations: From 200L steel drums to 24,000-liter ISO tanks and Flexibags, packaging formats are adapted to meet your regional port infrastructure and transport guidelines.

We work with established third-party laboratories such as SGS, BV, and Intertek to perform pre-shipment analysis (COA validation). This ensures that key criteria—including flash points, aromatic content, distillation ranges, and water levels—match your technical specification sheet before cargo departure.

Localized Application Scenarios & Global Industry Trends

The industrial consumption of heavy aromatic solvent naphthas is shifting toward optimized environmental performance. Global industrial trends show that regular Aromatic Solvent S200 grades are increasingly being replaced by low-naphthalene (LN) versions, which reduce hazardous air pollutant (HAP) profiles while preserving the physical solvency power of the hydrocarbon ring structure.

Arosol 200's specific high-boiling point cut and aromatic nature make it suitable for several key applications:

Agrochemical Formulations

Acts as an ideal solvent carrier for active pesticide ingredients in Emulsifiable Concentrates (EC) and Suspo-Emulsions (SE). It provides excellent dissolution performance, preventing crystallization of the active ingredient at low temperatures during storage.

Specialized Coatings & Paints

Utilized in high-temperature baked industrial finishes, automotive primers, protective marine coatings, and coil coatings. Its high boiling range supports smooth film formation by preventing rapid evaporation defects like blistering.

Oilfield Chemical Processes

Serves as a base solvent for drag reducers, corrosion inhibitors, demulsifiers, and paraffin dispersants. Its elevated flash point (≥ 100°C) is key to safety during high-temperature downhole operations.

In-Depth FAQ: Technical & Procurement Clarifications

To help chemical engineers and purchasing agents optimize their supply chains, we have addressed the most common technical questions regarding the sourcing, classification, and application of Arosol 200.

What is the primary difference between Arosol 200, Solvent S200, and Solvent Naphtha 200?

These terms are generally used interchangeably in the chemical industry. "Solvent Naphtha 200" and "Solvent S200" are generic industry descriptors for heavy aromatic hydrocarbon mixtures in the C10-C13 range with a boiling point between 230°C and 290°C. "Arosol 200" is a commercial brand name for this high-quality product. All of them fall under CAS No. 64742-94-5.

How does Shandong Saier Chemical guarantee the quality and purity of its Aromatic Solvents?

Our quality management system utilizes automated DCS systems to control the distillation column temperatures and pressure profiles. We conduct gas chromatography-flame ionization detection (GC-FID) and Karl Fischer titration analysis on every batch, providing a Certificate of Analysis (COA) that lists the precise aromatic concentration, distillation cuts, and water levels.

Does your factory offer a "Low-Naphthalene" (LN) variant of Arosol 200?

Yes. Regular S200 contains about 8% to 10% naphthalene, which is classified as a potential carcinogen. To meet international environmental standards, we produce Arosol 200 ND (Naphthalene Depleted), reducing the naphthalene content below 1.0% (and down to 0.1% for specific orders) through advanced vacuum fractional distillation.

What is the standard lead time for international bulk chemical orders?

Standard processing times for bulk orders (loaded in ISO tanks or steel drums) range from 10 to 15 days from order confirmation to port delivery in Qingdao. Transit times vary by shipping destination and port routing.
