Industrial Applications of 2-Butyl-1,2-benzisothiazolin-3-one
| Industry | Application | Process |
|---|---|---|
| Coatings & Paints | Preservative for water-based coatings, latex paints, and architectural coatings; prevents microbial degradation leading to spoilage, odor development, and pigment flocculation | Added directly during the final paint adjustment stage; recommended dosage: 0.05–0.2 wt% (based on active ingredient); effective pH range: 6–10 |
| Adhesives & Sealants | Preservative and anti-mold agent for water-based adhesives (e.g., PVA emulsions, starch adhesives) and acrylic sealants; inhibits growth of bacteria, fungi, and yeasts | Added after emulsion polymerization or at the final compounding stage; avoid high temperatures or strongly oxidizing conditions; recommended system pH: 5–9 |
| Metalworking Fluids | Biocide for cutting fluids, grinding fluids, and rolling oils; controls spoilage and odor caused by Gram-negative bacteria such as Pseudomonas spp. | Used in combination with other biocides (e.g., isothiazolinones); typical dosage: 50–200 ppm; regular monitoring of microbial load is required |
| Personal Care Products | Preservative for rinse-off and leave-on products (e.g., shampoos, body washes, hand soaps); use limited to concentrations ≤0.5% as approved under EU Regulation EC No. 1223/2009 Annex V | Added at ambient temperature after formulation cooling to below 40°C; avoid co-use with strong reducing agents or high-concentration sulfites |
| Paper Industry | Wet-end biocide and pulp preservative; prevents slime formation and biological deposits on paper machine wire sections | Dosed online in the pulp stock system; typical dosage: 50–150 g per metric ton of oven-dry pulp; pH adjustment recommended (optimal pH: 7–8) |
Manufacturing Quality Control of 2-Butyl-1,2-benzisothiazolin-3-one
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and state (usually white to light yellow crystalline powder) of the sample to determine if it conforms to the standard description. |
| Purity | HPLC (High-Performance Liquid Chromatography) | Use a reverse-phase column with methanol/water or acetonitrile/water as the mobile phase, and a UV detector (e.g., 254 nm) to quantitatively determine the main component content. |
| Content Determination | HPLC External Standard Method or Internal Standard Method | Determine the mass percentage of BBIT in the sample by comparing peak areas with a reference standard, typically requiring ≥98.0%. |
| Melting Point | Capillary Melting Point Method | Determine the temperature range for the solid-to-liquid transition (theoretical melting point of BBIT is approximately 155–158°C), to assess purity. |
| Dry Loss | Drying Loss Method (constant weight at 105°C) | Weigh the sample and dry it at a specified temperature until constant weight is achieved; calculate the moisture and volatile content, generally requiring ≤0.5%. |
| Residue on Ignition (Ash Content) | High-Temperature Ashing Method (800°C) | Heat the sample to high temperature to ash it, then weigh the residue to evaluate the content of inorganic impurities, typically requiring ≤0.1%. |
| Heavy Metal Content | Atomic Absorption Spectrometry (AAS) or ICP-MS | Dissolve the sample and measure the total or individual content of heavy metals such as lead, cadmium, mercury, and arsenic, which must comply with pharmacopoeia or environmental limits. |
| Related Substances (Impurities) | HPLC Gradient Elution Method | Use a gradient elution program to separate the main peak from impurity peaks, and control the total impurity content using area normalization or self-comparison methods. |
| pH Value (Solution) | pH Meter Measurement | Prepare a solution of the sample at a certain concentration (e.g., 1%) in water and measure its pH value to assess acidity, alkalinity, and stability. |
| Solubility | Solubility Test | Observe the dissolution behavior in specified solvents (water, ethanol, acetone, etc.) to confirm that the physical properties meet specification requirements. |
| UV Absorption Spectrum | UV-Vis Spectrophotometry | Scan the wavelength range of 200–400 nm to confirm the position of the maximum absorption peak (e.g., ~260 nm, ~300 nm), used for identification. |
| Infrared Spectroscopy Identification | Fourier Transform Infrared Spectroscopy (FTIR) | Compare characteristic absorption peaks (e.g., C=O, C-N, aromatic ring skeletal vibrations) with standard spectra for structural confirmation. |
