Methyl Propyl Ketone (commonly designated as MPK or 2-Pentanone, CAS 107-87-9) has consolidated its standing as an indispensable medium-boiling organic solvent. Within modern industrial coatings, electronics cleaning processes, and agrochemical formulations, MPK serves as a high-performance alternative to traditional solvents such as Methyl Ethyl Ketone (MEK) and Methyl Isobutyl Ketone (MIBK).
From a formulation physics perspective, MPK exhibits an optimized evaporation rate (1.0 compared to n-Butyl Acetate at 1.0) and lower density than esters, granting coating chemists superior control over viscosity reduction, flow characteristics, and dry times. These properties prevent common surface defects such as "blushing" or "orange peel" in premium automotive and aerospace finishes. Furthermore, its lower VOC footprint and compliant toxicological profile under modern occupational hygiene standards make it a preferred medium-evaporating carrier for high-solids and low-VOC acrylic, polyurethane, and nitrocellulose resin coatings.
Features a high Hansen Solubility Parameter (HSP) profile, facilitating prompt dissolution of synthetic resins, polymers, and natural gums.
Optimized evaporation behavior avoids early skinning in polyurethane coatings while facilitating flash-off speeds suitable for industrial lines.
Low density, high flashpoint relative to MEK, and low systemic toxicity yield a safer work environment without sacrificing solvency power.
Founded in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. has evolved into a key player in the chemical engineering landscape. Strategically headquartered at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, China, the company operates within one of the nation's most advanced chemical integration hubs.
Backed by a robust registered capital of 60 million yuan, our enterprise began with basic chemical products, rapidly transitioning to premium, high-purity specialties. We engineered an initial capacity footprint of 720,000 tons per year. Our core processing lines specialize in high-boiling aromatic solvents (including S-100, S-150, S-150ND, S-180, and S-200) marketed globally under major standards like TOPSOL, KOCOSOL, and SOLVESSO. Our expanded product suite integrates thermal management technologies (Heat Transfer Oil L-QC320), specialty intermediates (Durene, Thiophene, 1,3-Cyclohexanedione, MCC, MIPK, TMOF, TMOA, HPA, TMG), and high-demand ketones like Methyl Propyl Ketone (MPK).
By establishing long-term supply partnerships with Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical, Saier Chemical secures consistent, high-purity raw materials. Our distribution routes serve domestic industrial markets across Beijing, Shanghai, Tianjin, Hebei, Shandong, and Henan, alongside a global network exporting to Asia, Europe, the Americas, and Southeast Asia.
Our Methyl Propyl Ketone is synthesized using state-of-the-art catalytic dehydrogenation processes. This technology yields high-purity products with minimal moisture, acid, and organic byproducts, aligning with stringent global standards.

The global demand for high-performance solvents is shifting due to changing environmental regulations. Shandong Saier Chemical leads this transition through a technical roadmap focused on high-purity synthesis and reduced environmental impact. Our research team focuses on developing low-emission ketones that provide the solvent power of traditional options while mitigating VOC release.
Our roadmap targets advanced catalytic systems to replace conventional dehydrogenation catalysts. By utilizing multi-metal nano-catalysts, we improve single-pass conversion efficiency and reduce energy use in the distillation phase. In addition, our R&D efforts focus on bio-based pathways for Methyl Propyl Ketone, utilizing renewable carbohydrate feedstocks to offer a low-carbon product option for global buyers.
Looking ahead, we are expanding the application profile of MPK within the lithium battery manufacturing sector and high-frequency semiconductor cleaning processes. The compound's balanced evaporation rate and low viscosity make it a viable replacement for halogenated solvents. By optimizing purity levels and reducing trace metals to parts-per-billion (ppb) standards, Saier Chemical is positioning itself to support next-generation microelectronics manufacturing.
As industrial regulatory frameworks tighten, manufacturers require versatile chemical solutions. Methyl Propyl Ketone from Shandong Saier Chemical provides tailored advantages across several key sectors:
Serves as a medium-evaporating solvent in acrylic, epoxy, and polyurethane systems. It reduces viscosity to optimize formulation solids while helping to prevent run-off and surface defects.
Acts as an extraction solvent and chemical intermediate. MPK's chemical structure supports the synthesis of active pharmaceutical ingredients (APIs) and plant protection agents.
Provides effective degreasing and surface preparation for metal substrates and electronic components, leaving minimal residue and supporting structural adhesion.
At our plant in the Qilu Chemical Industrial Park, Shandong Saier Chemical has implemented automated production workflows under a Factory 4.0 design framework. Our processing facilities are managed by Distributed Control Systems (DCS), which continuously monitor temperature, pressure, flow rate, and purification metrics in real time. This automated control maintains consistent batch quality and reduces thermal footprint.
By locating our facility inside a national-level chemical park, we optimize logistical efficiency. Raw materials are sourced directly through pipeline connections and dedicated road transport from nearby Sinopec and PetroChina refining centers. This structural integration shields our manufacturing lines from feedstock disruptions. With a capacity of 720,000 tons per year across our primary solvent lines, we can adjust output to accommodate sudden market demands and high-volume commercial contracts.
For international supply chains, we maintain dedicated storage infrastructure at major coastal ports, enabling bulk tanker loading and multi-modal container transport. This logistics framework minimizes shipping delays and helps protect international buyers against volatile freight conditions.
Navigating international regulatory frameworks is critical for industrial chemical supply. Shandong Saier Chemical provides full compliance documentation for all shipments, including safety data sheets (SDS) structured for destination markets.
Our regulatory team supports REACH registration for EU clients, TSCA compliance for US imports, and national chemical registrations across East and Southeast Asia.
