Jiayuan High-Purity Hexafluoroisopropanol (HFIP) Targets Semiconductor and New Energy Industries

Jiayuan supplies 3N hexafluoroisopropanol (HFIP, CAS 920-66-1) with a purity ≥99.9%. 3N HFIP is not only a common solvent in pharmaceutical synthesis and polymer analysis, but it also unlocks high-end applications that industrial-grade HFIP (99.0%–99.5%) cannot reach. In advanced semiconductor processes and lithium-ion battery electrolytes, even trace impurities can cause a precipitous drop in performance, making 3N-grade HFIP an irreplaceable key material.   The watershed of 3N purityResidual fluorides, moisture, and metal ions in industrial-grade HFIP can interfere with precision manufacturing. Industry data shows that a purity of 99.95% to 99.99% is required to meet electronic-grade standards for photoresist cleaning of chips below 3 nanometers. 3N (≥99.9%) is a basic threshold for entering the semiconductor supply chain, and Jiayuan can provide batch-level testing data on metal ions, moisture, and fluorides to support certification. Special Application 1: Precision Cleaning of SemiconductorsHFIP has a boiling point of only 58.6°C (far lower than IPA's 82.4°C) and is non-flammable, eliminating the risk of combustion and explosion associated with traditional IPA cleaning. Early patents documented that wafers could be cleaned and dried simply by placing them in HFIP vapor, leaving no residue on the surface. The unique feature of Jiayuan's 3N grade lies in impurity control: photoresist residue cleaning requires the solvent not to introduce new metal ions or particles. Fluorides and moisture in low-purity products can cause surface defects, while the 3N grade uses processes such as molecular sieve membrane separation to reduce impurities to the ppb level. Special Application 2: Lithium-ion Battery ElectrolyteLithium hexafluoroisopropoxide (LiPOT), as an electrolyte additive, can preferentially reduce the graphite anode to form a more stable SEI film, suppressing side reactions and improving cycle stability. After addition, the electrolyte contact angle with the Celgard separator decreases from 41.0° to approximately 26°, reducing interfacial impedance. The significance of Jiayuan 3N's purity lies in moisture control: the electrolyte is extremely sensitive to moisture; even trace amounts of water accelerate LiPF₆ hydrolysis, leading to capacity decay. Jiayuan 3N HFIP typically maintains moisture levels below several hundred ppm, while industrial-grade moisture fluctuations can directly degrade batch consistency of batteries. FAQQ1: Is Jiayuan 3N HFIP equivalent to electronic grade?A: No, they are not the same. 3N (≥99.9%) is the minimum threshold for electronic grade, while the industry forefront has reached 99.99% (4N) to meet the requirements of processes below 3nm. Purity and metal impurity indicators should be confirmed according to the specific process node. Q2: Why does the lithium battery industry focus on HFIP derivatives rather than HFIP itself?A: HFIP functions as a film-forming additive in the form of lithium hexafluoroisopropoxide, and is a raw material for synthesizing this type of additive. Jiayuan's 3N grade reduces the introduction of impurities, ensuring additive consistency and electrochemical performance. Q3: What are the core advantages of 3N HFIP compared to IPA in semiconductor cleaning?A: Low boiling point of approximately 24°C, resulting in faster drying and lower energy consumption; non-flammable, eliminating the risk of combustion and explosion; good water compatibility, allowing for rapid replacement of moisture on the wafer surface; 3N purity ensures no metal contamination is introduced.2026-10-28

3N High-Purity CTFE for Advanced Fluoropolymer Manufacturing

I. High-purity trifluorochloroethylene, serving the needs of fine polymerizationChlorotrifluoroethylene (CTFE) is an important fluorinated polymer monomer with CAS number 79-38-9 and molecular formula C₂ClF₃. CTFE can be used to produce chlorotrifluoroethylene resins and is used in the synthesis of related plastics, elastomers, and high-performance lubricants.Changzhou Jiayuan Chemical Co., Ltd. provides trifluorochloroethylene products with a purity of up to 3N . For manufacturers of high-performance fluorinated materials, the core value of high-purity monomers lies in providing a clearer raw material quality basis for polymerization reactions, reducing the interference of non-target impurities on process evaluation, and supporting product consistency control.  II. Special Applications of High-Purity Raw Materials: Development of High-Performance PCTFE MaterialsPolychlorotrifluoroethylene (PCTFE) has good chemical resistance and gas and water vapor barrier properties, and can be used in high-barrier packaging, sealing components, cryogenic equipment and certain industrial materials.During PCTFE polymerization, the composition of impurities in the monomer can affect the polymerization reaction and the final resin quality. US Patent Document US5124494A discusses the byproducts, low-boiling-point impurities, and preparation of high-purity monomers in the PCTFE production process, illustrating that impurity control is a crucial step in obtaining suitable polymerization feedstocks.Therefore, 3N high-purity CTFE is particularly noteworthy for companies requiring stringent raw material acceptance, stable polymerization processes, and high-performance resin development. For applications such as low-temperature sealing and high-barrier materials, verification must be conducted in conjunction with resin grade, processing method, and end-use standards; the final product performance cannot be directly inferred from monomer purity alone. III. 3N Purity and Key Impurity ManagementA total purity of 3N means that, according to the corresponding purity definition, the total amount of non-target components is approximately 0.01%. However, total purity does not indicate the specific content of each impurity. For demanding polymerization applications, the purchaser should also pay attention to moisture, residual monomers, by-products, stabilizers, and other process-related impurities, and verify the testing methods and batch inspection reports.Jiayuan Chemical's trifluorochloroethylene products can achieve a purity of up to 3N. Customers can further confirm product specifications, critical impurity limits, packaging methods, and supply requirements based on their actual polymerization route and material application. ConclusionFor the development of high-performance PCTFE resins and other fluoropolymers, monomer purity and impurity control are crucial aspects of raw material evaluation. Jiayuan Chemical provides trifluorochloroethylene with a purity of up to 3N. Fluoropolymer manufacturers are welcome to inquire about product specifications, testing documents, and supply solutions. FAQ1. What applications are suitable for 3N high-purity trifluorochloroethylene?It can be primarily evaluated for use in the production of PCTFE and related fluoropolymers, and is particularly suitable for polymerization processes that emphasize raw material quality and impurity management. Specific applicability needs to be verified by the customer. 2. Why is it necessary to control impurities in high-purity trifluorochloroethylene?Different impurities can affect the polymerization reaction or the final resin quality. In addition to total purity, the content of critical impurities should be confirmed according to process requirements. 2026-10-23
