Industrial Applications of 4-Ethylaniline
| Industry | Application | Process |
|---|---|---|
| Chemical Intermediates | Intermediate for the synthesis of dyes and pigments | Used in the preparation of azo dyes via diazotization, coupling, and related reactions |
| Pesticide Industry | Synthetic precursor for pesticides (e.g., herbicides, fungicides) | Employed in organic synthesis steps—including acylation and alkylation—to construct active molecular structures |
| Pharmaceutical Industry | Intermediate for the synthesis of certain drug molecules (e.g., local anesthetics, anti-inflammatory agents) | Participates in reduction, substitution, or condensation reactions to generate target pharmaceutical compounds |
| Polymers Industry | Modifier or curing agent component for polyurethanes or epoxy resins | Reacts with isocyanate or epoxy groups to incorporate aromatic amine structures and enhance material performance |
| Analytical Chemistry | Reference standard or derivatization reagent for chromatographic or spectroscopic analysis | Used in laboratories for instrument calibration or derivatization of target analytes to improve detection sensitivity |
Manufacturing Quality Control of 4-Ethylaniline
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies 4-ethyl aniline peak area relative to internal/external standard using retention time and calibration curve. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions using visual match or absorbance at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube) | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry (Abbe refractometer) | Measures refractive index based on critical angle of total internal reflection at prism-sample interface. |
| Acid Value | Acid-Base Titration (NaOH in ethanol) | Neutralizes acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Ignition at 700-800 C) | Weighs non-volatile residue remaining after high-temperature incineration of a weighed sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies metal content by measuring absorption of specific wavelength light by ground-state metal atoms in flame. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Detects and identifies chlorinated organic impurities based on retention time and characteristic mass fragmentation patterns. |
| Aniline Derivatives (e.g., nitroanilines) | High-Performance Liquid Chromatography (HPLC-UV) | Separates and quantifies structurally related impurities using reversed-phase column and UV detection at 254 nm. |
| Sulfated Ash | Gravimetric Analysis (H2SO4 treatment + ignition) | Measures inorganic residue after sulfuric acid digestion and subsequent high-temperature ignition. |
| Boiling Range | Distillation (Micro or Semi-micro Apparatus) | Determines temperature interval over which 10% to 90% of sample distills under controlled atmospheric pressure. |
