Industrial Applications of n-Butyl fumarate
| Industry | Application | Process |
|---|---|---|
| Coatings & Inks | Serves as a solvent for nitrocellulose, ethylcellulose, vinyl resins, etc., improving coating flow and gloss. | Surface coating formulation |
| Plastics & Resins | Acts as a plasticizer for vinyl resins (e.g., PVC) and acrylic resins, enhancing material flexibility and processability. | Blending and plasticization |
| Adhesives | Functions as a solvent or plasticizer to adjust adhesive viscosity and drying rate. | Solvent-based adhesive preparation |
| Cellulosic Products | Used in processing nitrocellulose lacquers and synthetic leather, imparting soft hand feel and good adhesion. | Cellulose ester plasticization |
| Pharmaceuticals & Agrochemicals | Serves as a solvent or intermediate in the synthesis and formulation of active pharmaceutical ingredients or agrochemical products. | Chemical synthesis or formulation |
| Organic Synthesis | Acts as an intermediate in polymerization of olefinic monomers or in the production of other organic compounds (e.g., fragrances, surfactants). | Chemical synthesis |
Manufacturing Quality Control of n-Butyl fumarate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state under natural light or standard illumination (typically a colorless to pale yellow transparent liquid). |
| Purity | Gas Chromatography (GC) | Separation using a capillary column with FID detection; main component content is calculated by area normalization or external standard method. |
| Moisture Content | Karl Fischer Titration | Quantitative reaction of iodine with sulfur dioxide in a methanol-pyridine system with water, used to determine trace moisture levels in samples. |
| Acid Value | Acid-Base Titration | Titrate free acids using standardized potassium hydroxide in ethanol solution with phenolphthalein as indicator; acid value is expressed as mg KOH required to neutralize 1 g of sample. |
| Density | Density Meter Method / Specific Gravity Bottle Method | Measure sample density at a specified temperature (e.g., 20°C) using a density meter or specific gravity bottle to assess product consistency. |
| Refractive Index | Abbe Refractometer Method | Determine refractive index at standard temperature (e.g., 20°C), used to assist in purity assessment or substance identification. |
| Boiling Range / Distillation Range | Distillation Method | Use standard distillation apparatus to measure the temperature range from initial boiling point to dry point, evaluating distribution of volatile components and impurities. |
| Color | Platinum-Cobalt Colorimetry / Gardner Color Scale | Compare sample color visually against standard color solutions, expressed in color numbers to indicate depth of color and reflect oxidation or impurity levels. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Heat the sample to release volatile organic solvents, then analyze solvent types and concentrations using GC-FID or GC-MS. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine total levels of heavy metals such as lead, arsenic, mercury, and cadmium to ensure compliance with safety limits. |
