Explore our high-purity industrial intermediates, aromatic solvents, and specialized synthesis ingredients.
In modern industrial chemistry, the demand for highly efficient, low-toxicity solvents has shifted from a peripheral preference to a core regulatory mandate. Solgad 150 ND (Naphthalene Depleted), also widely processed and distributed as Aromatic Solvent S150 ND, represents a vital milestone in this transformation. Traditional Aromatic 150 solvents naturally contain significant levels of naphthalene, a compound heavily scrutinized under global occupational safety and environmental frameworks. Solgad 150 ND addresses this hazard by utilizing advanced, highly controlled distillation systems that selectively deplete naphthalene content to less than 1.0% (and often below 0.1% for ultra-pure requirements), while retaining the high solvency, high flash point, and excellent evaporation profile expected of heavy aromatic hydrocarbons.
As a leading supplier in the chemical intermediates space, Shandong Saier Chemical Technology Development Co., Ltd. has developed specialized manufacturing protocols to meet the stringent demands of crop protection, chemical synthesis, and industrial surface coatings. Our refining methodologies ensure that key parameters, such as aniline point, distillation range (typically 180°C to 210°C), and aromatic content (minimum 99%), remain stable batch after batch, protecting our clients' downstream formulations from phase separation or crystal sedimentation.
A Pioneering Petrochemical and Fine Chemical Hub Driven by Technology, Scale, and Sustainable Quality Processes.
Established in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. has grown from a regional producer into a powerhouse within the Qilu Chemical Industrial Park, situated at No. 207 WeiLiu Road, Linzi, Zibo City, Shandong Province. With a solid initial foundation built on a registered capital of 60 million yuan, Saier Chemical has strategically leveraged its location adjacent to China's leading petrochemical refineries—including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical—to guarantee an uninterrupted, premium supply of hydrocarbon feedstocks.
Over the past two decades, the company has scaled its production infrastructure to a robust capacity of 720,000 tons per year. Our core expertise lies in refining environmentally friendly high-boiling aromatic solvents, including S-100, S-150, S-150ND, S-180, and S-200, alongside essential heat transfer oils (such as L-QC320), durene, PVC plasticizers, thiophene, 1,3-cyclohexanedione, MIPK, TMOF, TMOA, HPA, and TMG. This broad chemical matrix serves key domestic hubs like Beijing, Shanghai, Hebei, and Henan, and feeds dynamic export pipelines into Europe, North America, Southeast Asia, and the Middle East.
Analyzing the shift from commodity heavy aromatic naphthas to regulatory-compliant, high-safety solvents.
Under EPA regulations and the EU Green Deal, pesticides formulated with conventional heavy aromatics face strict environmental labeling requirements. Solgad 150 ND eliminates hazardous classification warning requirements related to aquatic toxicity caused by high naphthalene concentrations, allowing agrochemical brands to retain their green label status.
Traditional solvents with >1% naphthalene trigger GHS Category 2 carcinogen labeling, placing heavy compliance burdens on manufacturers. Upgrading to Solgad 150 ND reduces plant exposure limits, simplifies handling logistics, and lowers employee safety risks during mixing, packaging, and spraying.
Modern crop protection formulations rely on Emulsifiable Concentrates (EC) and Microemulsions (ME). The removal of naphthalene from the solvent prevents low-temperature crystallization of both active ingredients and the solvent itself, ensuring long shelf life and stable application under cold-weather conditions.
Procuring raw chemical materials at a global scale requires balancing cost efficiency with strict technical parameters. For global sourcing managers, the main challenges revolve around batch-to-batch consistency and high purification costs. In response, Saier Chemical has optimized its high-efficiency distillation systems to stabilize critical parameters, ensuring that the heavy aromatic fractions (C10-C12) are tightly controlled.
Our raw material integration is key to our reliability. By partnering directly with state-owned refiners like Sinopec and PetroChina, we prevent feedstock disruptions, guaranteeing that our annual capacity of 720,000 tons remains fully functional even during volatile energy market cycles. Furthermore, our strategically located facility in Zibo City, Shandong, grants us immediate access to major international ports, facilitating fast bulk transport via ISO tanks, flexitanks, or standard 200L steel drums.
Cross-industry applications highlighting high solvency, safe flash points, and low VOC impacts.
Used as a primary solvent for active ingredients like pyrethroids, triazoles, and phenoxy acid herbicides. Solgad 150 ND stabilizes Emulsifiable Concentrates (EC) over broad temperature variations, preventing crystallization and ensuring complete emulsion stability in spray tanks.
Serves as a solvent in high-bake enamels, maintenance coatings, and protective finishes. Its slow, controlled evaporation rate ensures excellent leveling, high gloss development, and minimizes paint defects like blistering or pinholing.
Ideal as a reaction medium or heat carrier oil component due to its high boiling point range (180°C–210°C) and excellent thermal stability. Often preferred over lighter fractions to reduce volatile organic compound (VOC) emissions during processing.
Saier Chemical's strategic roadmap toward green chemistry, circular systems, and cleaner production.
Upgraded fractionating columns with high-efficiency structured packing, achieving naphthalene separation down to <0.9% for our Solgad 150 ND and S-200 ND product series.
Implemented heat-exchanger networks across distillation systems. These optimizations significantly reduce carbon footprint and steam consumption per ton of solvent refined.
R&D focusing on blending bio-derived esters with naphthalene-depleted heavy aromatics to offer hybrid, highly biodegradable green solvents tailored for agricultural applications.
Answering technical, environmental, and commercial questions for B2B buyers and formulators.
"ND" stands for Naphthalene Depleted. Standard Aromatic 150 fluid naturally contains 8% to 10% naphthalene, a chemical classified as a possible human carcinogen. Solgad 150 ND is refined to reduce this content below 1.0% (and often below 0.1%), addressing health, safety, and environmental regulations while maintaining strong solvency.
Both have the same base boiling range (approx. 180°C - 210°C), aromatic content (>99%), flash point (>62°C), and solvency behavior. The only difference is the naphthalene content: standard S150 has up to 10% naphthalene, whereas S150 ND has less than 1.0%, making it safer and cleaner for agricultural use.
It offers excellent solvency for complex active ingredients (APIs). Low-naphthalene solvents prevent crystallization of the active ingredient at low temperatures, ensuring uniform emulsion stability during spray applications and extending the product shelf life.
