Industrial Applications of Benzohydroxamic acid
| Industry | Application | Process |
|---|---|---|
| Mineral Processing | Collector for flotation of non-ferrous sulfide and oxide ores, including copper, lead, zinc, and tin | Used as a selective collector in flotation processes to enhance recovery and grade of target minerals |
| Metallurgy | Extraction and separation of metal ions | Applied as a chelating extractant in solvent extraction to selectively recover metal ions—such as copper, iron, and zirconium—from acidic solutions |
| Analytical Chemistry | Colorimetric reagent and masking agent for metal ions | Employed in spectrophotometric determination of metals—including iron, copper, and molybdenum—and as a masking agent for interfering ions in complexometric titrations |
| Pharmaceutical Intermediates | Precursor for synthesizing antimicrobial and antitumor active compounds | Integrated as a hydroxamic acid structural motif in pharmaceutical molecule synthesis |
| Materials Science | Metal surface treatment and corrosion inhibition | Applied in metal passivation treatments to suppress corrosion reactions |
| Environmental Engineering | Removal of heavy metal ions from wastewater | Used in chelation precipitation or adsorption processes to form stable complexes with heavy metals for effective removal |
Manufacturing Quality Control of Benzohydroxamic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies benzohydroxamic acid by titration with standardized NaOH using phenolphthalein indicator, based on its acidic hydroxyl group. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric reaction between water and iodine in a methanol-based reagent. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting and against standard references. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual material. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal impurities (e.g., Pb, Cd, Fe) after acid digestion using element-specific absorption of UV-Vis light. |
| Chloride Impurity | Potentiometric Titration | Detects chloride ions by titration with silver nitrate using a silver indicator electrode and reference electrode. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after ignition with sulfuric acid treatment to convert metals to sulfates. |
| Organic Volatile Impurities | Gas Chromatography (GC) | Separates and quantifies residual solvents or volatile organic impurities using capillary column and FID detection. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Identifies and quantifies structurally related impurities (e.g., benzohydrazide, benzoic acid) using reversed-phase C18 column and UV detection. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of a defined aqueous suspension or solution using calibrated glass electrode. |
| Bulk Density | Graduated Cylinder Method | Measures mass per unit volume of freely settled powder using standardized cylinder and weight measurement. |
