001×4 Styrene series Gel Strong Acid Cation Exchange Resin
About this Product:
The 001×4 is a strong acid cation exchange resin with a sulfonic acid functional group. The resin is based on a styrene-divinylbenzene copolymer with a 4% crosslinkage. Performance-wise, it is an effective alternative to products such as Amberlite IR-118.
At a Glance
The 001×4 is a strong acid cation exchange resin with a lower crosslinkage (4% DVB) compared to the more common 7-8% resins. This lower crosslinking gives it unique properties that make it particularly well-suited for specific applications.
Key Applications:
- Extraction of Antibiotics and Pharmaceuticals: The lower crosslinkage provides a more open polymer matrix, which allows larger organic molecules, such as those found in antibiotics and other pharmaceuticals, to diffuse into the resin beads more easily. This makes it highly effective for the extraction, separation, and purification of these high molecular weight compounds from solutions.
- Preparation of Pure Water or High-Purity Water: Like other strong acid cation resins, it is used for the removal of cations (e.g., Na+, Ca2+, Mg2+) from water sources. It is often used as part of a two-stage demineralization system to produce high-purity water for various industrial and laboratory processes.
- Water Softening: While a 7-8% crosslinked resin is more common for standard water softening, the 001×4 can also be used. Its lower crosslinking may offer faster exchange kinetics, which can be advantageous in certain flow conditions, but it may have lower physical strength and capacity compared to higher crosslinked versions.
- Catalysis: The sulfonic acid functional groups in the resin can act as a solid acid catalyst. The 4% crosslinkage provides a less rigid structure, which can be beneficial for certain organic reactions where access to the catalytic sites is critical for larger reactant molecules.
- Separation and Purification of Biochemicals: The more open structure of the 4% crosslinked resin makes it suitable for the separation and purification of various biochemical compounds, including amino acids, where the size of the molecules is a significant factor.
