Industrial Applications of Guanidinium dihydrogen phosphate
| Industry | Application | Process |
|---|---|---|
| Wood Processing | Wood flame retardant | Used as a primary or secondary flame-retardant component, applied to wood via impregnation, brushing, or pressure injection to reduce combustibility and improve fire-resistance rating. |
| Textile Industry | Flame-retardant finishing of fabrics | Applied in durable flame-retardant finishing of cotton, linen, polyester, and other fibers; commonly formulated with urea and dicyandiamide, then cured onto fiber surfaces via high-temperature baking. |
| Plastics Industry | Flame-retardant additive for plastics | Used as a halogen-free flame retardant in processing nylon (PA6, PA66), polypropylene (PP), and other thermoplastics to enhance flame resistance and suppress melt dripping during combustion. |
| Paper Industry | Paper flame retardant | Added to pulp or applied as a surface coating to impart flame resistance to paper; commonly used in the production of fire-resistant and electrical insulation papers. |
| Coatings Industry | Intumescent fire-retardant coatings | Serves as a dehydrating catalyst and blowing agent, combined with char formers (e.g., pentaerythritol) and blowing agents to form an insulating, expanded char layer upon exposure to fire, thereby limiting heat transfer. |
| Synthetic Materials | Synthetic intermediate | Used as a building block in synthesizing other flame retardants or fine chemicals, such as higher-molecular-weight condensed guanidine phosphate flame retardants. |
| Water Treatment | Corrosion inhibitor | Functions as a component of metal corrosion inhibitors in specific industrial closed-loop water systems to prevent corrosion of copper, aluminum, and other metallic equipment. |
Manufacturing Quality Control of Guanidinium dihydrogen phosphate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Guanylphosphate Content) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH after acid hydrolysis to release phosphate. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in pyridine-methanol medium. |
| pH of 1% Aqueous Solution | Potentiometric pH Measurement | Determines acidity/basicity using calibrated pH electrode in a standardized aqueous suspension. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring absorbance of ground-state atoms at characteristic wavelengths. |
| Iron (Fe) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Detects Fe concentration based on element-specific atomic emission intensities after plasma atomization. |
| Chloride (Cl-) | Argentometric Titration (Mohr Method) | Determines chloride by titration with AgNO3 using K2CrO4 as indicator for endpoint detection. |
| Sulfate (SO42-) | Gravimetric Analysis | Precipitates sulfate as BaSO4, followed by drying and weighing to calculate sulfate content. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by ignition at 700-800 C and weighing residual ash. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size by measuring angular variation in intensity of laser light scattered by suspended particles. |
| Bulk Density | Volumetric Method | Determines mass per unit volume by measuring weight of sample freely poured into a calibrated cylinder. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) | Measures volatile loss including water and solvents by monitoring mass change during controlled heating. |
| Organic Impurities | High Performance Liquid Chromatography (HPLC) | Separates and quantifies organic contaminants using reversed-phase column and UV detection. |
