tris(2-butoxyethyl) phosphate with the CAS number 78 - 51 - 3 is a high - quality chemical product offered at the best price. This chemical is a clear liquid with a characteristic odor. It has a molecular formula of C₁₈H₃₉O₇P and a molecular weight of approximately 398.47 g/mol. The density of this product is around 0.996 g/cm³ at 20°C. It has a boiling point in the range of 220 - 250°C at 5 mmHg. The refractive index of this tris(2 - butoxyethyl) phosphate is about 1.437.
It is insoluble in water but soluble in many organic solvents such as ethanol, acetone, and toluene. These physical and chemical properties make it suitable for a variety of industrial applications.
1. As a plasticizer: tris(2 - butoxyethyl) phosphate is widely used as a plasticizer in the plastics industry. It can improve the flexibility, durability, and processability of plastics. For example, it can be added to polyvinyl chloride (PVC) to make it more flexible and less brittle, which is suitable for the production of cables, flooring, and other plastic products.
2. Flame retardant: It has flame - retardant properties. When added to polymers such as polyurethane foams, it can slow down or prevent the spread of fire, enhancing the fire safety of the materials.
3. Solvent and stabilizer: In some industrial processes, it can act as a solvent for certain chemicals and also as a stabilizer to prevent the degradation of other substances.
1. Storage: Store tris(2 - butoxyethyl) phosphate in a cool, dry, and well - ventilated place. Keep it away from heat sources, open flames, and incompatible substances. The container should be tightly sealed to prevent leakage.
2. Handling: When handling this chemical, appropriate personal protective equipment should be worn, including chemical - resistant gloves, safety glasses, and a lab coat. Avoid direct contact with skin, eyes, and clothing. In case of contact, rinse immediately with plenty of water and seek medical advice.
3. Mixing: If it is used as a plasticizer or flame retardant, it should be mixed thoroughly with the base material according to the recommended proportion. The mixing process should be carried out under suitable conditions, such as proper temperature and agitation, to ensure uniform dispersion.
1. PVC cable production: In a large - scale PVC cable manufacturing plant, tris(2 - butoxyethyl) phosphate is added to the PVC resin during the extrusion process. The plasticizer improves the flexibility of the cable sheath, making it easier to bend and install. It also enhances the electrical insulation properties of the cable. After long - term use, the cables show no signs of cracking or brittleness, indicating the effectiveness of this plasticizer in maintaining the integrity of the cable structure.
2. Furniture foam: A furniture manufacturer uses tris(2 - butoxyethyl) phosphate as a flame retardant in polyurethane foams for sofa cushions. During fire tests, the treated foams show a significant reduction in the spread of flames compared to untreated foams. This not only meets the fire safety standards but also provides a safer environment for consumers.
