Explore our core chemical lines manufactured under strict ISO9001:2015 quality standards and distributed globally through integrated logistics hubs.
High Purity Ethanol (CAS No. 64-17-5), specifically in its anhydrous form (≥99.5% to ≥99.9% purity), represents a foundational liquid chemical vector across global bio-pharmaceutical manufacturing, semiconductor substrate processing, fine chemical synthesis, and advanced cosmetic extraction. As global environmental mandates shift chemical processing toward carbon-neutral vectors and ultra-low trace-impurity tolerances, high-purity ethanol has evolved from a commodity bulk solvent into a precisely engineered utility component.
Standard industrial ethanol yields water content between 4.0% and 7.0% due to the naturally occurring ethanol-water azeotrope (95.6% ethanol by weight). Overcoming this thermodynamic barrier demands molecular sieve dehydration, extractive distillation, or pervaporation membrane filtration. Shandong Pulisi Chemical leverages advanced pressure-swing adsorption (PSA) technologies to deliver custom OEM anhydrous ethanol with water levels controlled down to ≤100 ppm, tailored precisely for water-sensitive catalytic reactions and electronic wafer degreasing.
Shandong Pulisi Chemical Co., Ltd. was established in 2006 (Stock Code: 307785). The company focuses on petrochemicals, mining chemicals, feed chemicals, and pharmaceutical chemicals. At present, the company has established long-term and stable partnerships with Fortune Global 500 companies such as China National Petroleum Corporation (CNPC) and Saint-Gobain. We always take customer demand as the core orientation and provide tailored solutions to help customers strengthen their market competitiveness.
The company has passed ISO9001:2015 Quality Management System Certification and German BV Certification, and has been awarded multiple honors such as Foreign-Oriented Economic Enterprise, Alibaba Demonstration Base, and Contribution Enterprise. In 2023, the company successfully went public with stock code: 307785.
The company upholds the corporate culture philosophy of “Customer First, Rapid Response; Striving as the Foundation, Efficient Collaboration; Integrity and Uprightness, Agile Adaptation.” We focus on providing compliant and high-quality products and supporting services, and are committed to becoming a long-term and stable partner for customers.
Meanwhile, the company has established mature warehousing and distribution systems at key logistics hubs, including Qingdao Port, Tianjin Port, and Xinjiang border ports (Alashankou, Khorgos). We are able to provide flexible supply solutions according to customer needs to ensure timely order delivery. No matter where customers are located, Shandong Pulisi Chemical will safeguard their business development with professional service systems and efficient response capabilities.
The global high purity ethanol market is experiencing structural growth, propelled by strict environmental regulations, pharmaceutical expansion, and high-tech semiconductor solvent requirements. Industry forecasts indicate an acceleration in demand for specialty grade ethanol formulations, driven by regional industrial dynamics:
Driven by strict USP (United States Pharmacopeia) and EP (European Pharmacopoeia) compliance. High demand for bio-derived, high-purity ethanol for botanical extraction, vaccine formulation media, and green chemical synthesis.
Rapid expanding manufacturing footprint in electronic-grade high-purity ethanol. Used extensively in semiconductor photolithography, wafer rinsing, and micro-display production lines in East Asian tech clusters.
Expanding usage in oil and gas processing, water-treatment chemical formulations, and cross-border industrial solvents via land-port networks such as Khorgos and Alashankou.
Because ethanol forms an azeotrope with water at 95.6% ethanol composition under atmospheric pressure, standard distillation towers cannot achieve higher purities. Shandong Pulisi Chemical utilizes a multi-stage purification technology matrix to produce grade-specific ethanol options for international clients.

Our facility utilizes synthetic 3A zeolite molecular sieves operating in a dual-bed pressure swing adsorption configuration. The 3A pore structure selectively adsorbs water molecules (≈2.8 Å) while excluding ethanol molecules (≈4.4 Å), yielding continuous anhydrous stream output without chemical contamination.
For large-scale industrial OEM requirements, entrainer-assisted extractive distillation combined with polymeric pervaporation membranes allows low-energy dehydration, maintaining stable thermal integrity and avoiding trace aldehyde formation.
Shandong Pulisi Chemical provides comprehensive OEM/ODM formulation, custom denaturing, and tailored packaging designed to withstand extreme international shipping conditions.
Tailored denaturing according to national regulations: Isopropanol (IPA), Methanol, Methyl Ethyl Ketone (MEK), Denatonium Benzoate (Bitrex), and custom ratio industrial spirits for paint, coating, and printing application.
Available in UN-certified 200L HDPE Drums, 200L Steel Drums, 1000L IBC Totes, ISO Tank Containers (24,000L), and specialized Flexitanks with nitrogen-blanketed sealing to prevent moisture re-absorption.
