Industrial Applications of 694-53-1
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Reducing agent for hydrosilylation reactions | Under platinum-group catalysts, undergoes addition reactions with unsaturated compounds (e.g., alkenes, alkynes) to produce organosilicon intermediates |
| Materials Science | Preparation of silicon-containing polymers and silicon-based functional materials | Serves as a precursor in sol-gel processes for synthesizing siloxane-based polymers or hybrid materials |
| Semiconductor Manufacturing | Silicon source for chemical vapor deposition (CVD) | Thermally decomposes at elevated temperatures to deposit amorphous silicon thin films, used for passivation or buffer layers in microelectronic devices |
| Pharmaceutical Intermediate Synthesis | Selective reducing agent | Reduces specific functional groups (e.g., acyl chlorides, azides) under mild conditions for structural modification of drug molecules |
Manufacturing Quality Control of 694-53-1
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a transparent glass container and observe its color, transparency, and presence of suspended matter or precipitate under natural light or a standard light source. Pure phenylsilane is a colorless and transparent liquid. |
| Content/Purity | Gas Chromatography (GC) | Using a capillary gas chromatograph equipped with an FID detector, quantify the main component content of phenylsilane by comparing retention time and peak area with those of a standard. Suitable for high-purity sample analysis with high sensitivity. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of GC with the qualitative identification power of MS to detect and identify organic impurities (e.g., diphenylsilane, styrene) in the sample. |
| Moisture Content | Karl Fischer Titration | Measures trace water content based on the quantitative reaction of iodine with sulfur dioxide in methanol in the presence of water. Can be performed by coulometric or volumetric methods. Suitable for moisture-sensitive silane compounds. |
| Active Hydrogen Content (Si-H) | Proton Nuclear Magnetic Resonance (¹H NMR) | Dissolve the sample in a deuterated solvent (e.g., CDCl₃). The Si-H content is calculated by integrating the signal corresponding to the chemical shift (δ ≈ 4.0–5.0 ppm). Used for structural confirmation and semi-quantitative analysis. |
| Hydrolysis Titration | Phenylsilane reacts with water to release hydrogen gas. The amount of active Si-H groups is determined indirectly by measuring the volume or pressure of generated hydrogen gas. Must be performed under inert atmosphere. | |
| Density | Densitometer / Pycnometer Method | Measure liquid density using a precision densitometer or pycnometer at a specified temperature (e.g., 20°C), useful for assessing purity and batch consistency. |
| Boiling Point | Micro Boiling Point Determination | Determine boiling range under atmospheric or reduced pressure using a micro-distillation apparatus. The boiling point of pure phenylsilane is approximately 160–162°C (atmospheric pressure); deviations indicate the presence of impurities. |
| Acidity/Alkalinity | pH Test Paper or Potentiometric Titration | Dissolve the sample in a suitable solvent (e.g., isopropanol) and measure the pH of the solution to determine the presence of acidic or basic impurities (e.g., hydrochloric acid, amines). |
