Industrial Applications of CROTONYL CHLORIDE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of pharmaceutical intermediates for antitumor, antiviral, and other active compounds | Used as an acylating agent in condensation reactions to construct drug molecules containing unsaturated acyl groups |
| Agrochemicals | Synthesis of intermediates for insecticides, herbicides, and other agrochemicals | Introduces trans-crotonyl functional groups via nucleophilic substitution or addition reactions |
| Organic Synthesis | Key raw material for constructing α,β-unsaturated carbonyl compounds | Undergoes typical acyl chloride reactions (e.g., Schotten-Baumann reaction) with amines, alcohols, or phenols to yield corresponding amides or esters |
| Materials Science | Synthesis of specialty polymer monomers or functional polymers | Acts as a comonomer in free-radical or step-growth polymerization to introduce crosslinkable or reactive side chains |
Manufacturing Quality Control of CROTONYL CHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (trans-Crotonyl Chloride) | Gas Chromatography (GC) with FID | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual HCl) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass under controlled temperature, followed by weighing of non-volatile residue. |
| Color | Visual Comparison or APHA Color Scale | Comparison of sample color in a Nessler tube against platinum-cobalt standard solutions under controlled lighting. |
| Density at 20 C | Digital Density Meter | Measurement of sample density via oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Determination of refractive index using a calibrated Abbe refractometer at specified temperature. |
| Chloride Ion (as Cl-) | Potentiometric Titration with AgNO3 | Titration with silver nitrate using a silver/silver chloride electrode to detect endpoint via potential change. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion and dilution, based on characteristic atomic emission intensities. |
| Non-Volatile Residue | Gravimetric Analysis | Heating a weighed sample to 105 C until constant mass, then measuring residual solids. |
| Aldehyde Impurities (e.g., acetaldehyde) | GC-MS | Separation and identification of volatile aldehyde impurities using capillary GC coupled with electron ionization mass spectrometry. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, followed by titration with standardized sodium thiosulfate. |
