Industrial Applications of Diethyl succinate
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Pharmaceutical intermediates (e.g., synthetic vitamin B1, sulfonamides) | Used as a raw material or solvent in esterification reactions |
| Flavor & Fragrance Industry | Formulation of food and personal care fragrances | Used as a fixative or modifier for fruit notes (e.g., grape, peach) |
| Food Industry | Food additive | Added in accordance with food safety standards to enhance flavor |
| Plastics & Coatings Industry | Solvent | Used to dissolve nitrocellulose, cellulose acetate, and resins |
| Organic Synthesis | Synthetic raw material | Used in the production of high-performance plasticizers and specialty surfactants |
| Paints & Coatings Industry | High-boiling solvent | Used to improve coating flow and film-forming properties |
| Dye Industry | Penetrating agent | Used in the processing of certain dyes |
| Chemical Analysis | Analytical reagent | Used in gas chromatography analysis or as a reference standard |
Manufacturing Quality Control of Diethyl succinate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state under natural light or standard lighting conditions to determine whether it is a colorless, transparent liquid, and check for turbidity, precipitation, or foreign particles. |
| Colorimetry | Platinum-Cobalt Colorimetric Method (GB/T 3143) | Compare the sample with a platinum-cobalt standard color scale to quantitatively assess color intensity, used to control raw material purity. |
| Purity (Content) | Gas Chromatography (GC) | Use capillary columns (e.g., HP-5, DB-WAX) and FID detector; identify components by retention time, and quantify the main component using area normalization or external standard method. |
| Moisture Content | Karl Fischer Titration | Utilize the quantitative reaction between iodine and sulfur dioxide in a pyridine/methanol system with water; used to determine trace moisture content in organic solvents. |
| Acid Value (Acidity) | Acid-Base Titration | Titrate free acids (e.g., unesterified succinic acid) in the sample with standardized sodium hydroxide in ethanol solution; calculate acid value (mg KOH/g) based on the amount of base consumed. |
| Density | Density Meter Method or Specific Gravity Bottle Method | Measure mass per unit volume at a specified temperature (e.g., 20°C) using a density meter or specific gravity bottle, used for auxiliary identification and purity assessment. |
| Refractive Index | Refractometry (Abbe Refractometer) | Determine the refractive index at a standard temperature (e.g., 20°C), serving as a physical constant for authenticity verification and purity evaluation. |
| Boiling Point / Distillation Range | Distillation Method (Boiling Range Determination) | Use a standard distillation apparatus to measure initial boiling point and dry point, assessing volatility and compositional consistency, and detecting low-boiling or high-boiling impurities. |
| Impurity Profiling (Related Substances) | Gas Chromatography-Mass Spectrometry (GC-MS) | Combine GC separation capability with MS qualitative analysis to identify and characterize organic impurities (e.g., by-products, degradation products, residual solvents). |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Employ headspace injection to detect possible residual organic solvents (e.g., ethanol, benzene derivatives) from production processes, meeting pharmacopeial requirements for residual solvents. |
