What kind of catalyst is needed for the preparation of Triisobutyl Phosphate TIBP?
This product is made from phosphoric acid and isobutyl alcohol, and concentrated sulfuric acid is needed as a catalyst. Put phosphoric acid in a copper reactor, add isobutyl alcohol, the ratio of the two is 1:3, and then add a little concentrated sulfuric acid, the amount of which is 3% of the total amount of raw materials. Heat to 120 degrees to make the reaction generate water and Triisobutyl Phosphate TIBP, separate the water through a distillation column, and continue to react for four hours. The process is like brewing alcohol, and the catalyst promotes the rapid reaction, but the amount should not be too much, too much will corrode the reactor body, and too little will slow the reaction. Only the right amount can have a high yield, and the purity of the finished product can reach 98%.
What role does Triisobutyl Phosphate TIBP play in the plastic industry?
This product is a good material for plasticizers. Adding it to polyvinyl chloride plastics can make the products soft and cold-resistant, and will not crack at minus 20 degrees. It has good compatibility with resins, and there is no precipitation even when the addition amount reaches 30%, making the plastic surface smooth and non-greasy. In cable materials, it can enhance insulation performance, increase voltage resistance by 30%, and resist aging. It will not crack after being exposed to sunlight for half a year. It has low volatility and is more resistant to migration than phthalates, so it is safer to use in plastic toys and food packaging, meets environmental standards, and is favored by the plastic industry.
What are the characteristics of Triisobutyl Phosphate TIBP's chemical properties?
This product is a colorless, transparent liquid with a slight ester fragrance. It is insoluble in water and easily soluble in organic solvents such as ethanol and ether. It is stable at room temperature. It hydrolyzes into phosphoric acid and isobutyl alcohol when it encounters strong acids, and saponifies when it encounters strong alkalis. Therefore, it needs to avoid acids and alkalis when it is stored. The boiling point is about 260 degrees. It is not easy to volatilize at high temperatures, so it is suitable for plastics processed at high temperatures. It has a high flash point of about 110 degrees. It is a non-flammable liquid and does not need to be stored away from fire sources. It is compatible with metals and does not corrode copper, iron, aluminum and other utensils, so it can be transported in iron barrels.
What are the advantages of Triisobutyl Phosphate TIBP compared with other phosphates?
Compared with tributyl phosphate, Triisobutyl Phosphate TIBP is less volatile, can be retained in plastics longer, and has a long-lasting plasticizing effect. Compared with triethyl phosphate, it has better cold resistance and is suitable for products in low-temperature environments. In the extraction process, its ability to extract metal ions is slightly weaker, but its toxicity is lower and the operation is safer. Its production cost is 15% lower than that of triphenyl phosphate, and its color is lighter. It does not affect the light transmittance when used in transparent plastics, so it has better cost performance and wider application.
Are there any special requirements for the storage of Triisobutyl Phosphate TIBP?
This product needs to be stored in galvanized iron barrels with sealed barrel mouths to prevent volatilization. Store in a cool and ventilated warehouse with a temperature not exceeding 30 degrees, away from fire and heat sources, and isolated from strong acids and strong alkalis. The barrel body must be placed upright, not inverted, to prevent leakage. If the barrel mouth leaks, it needs to be moved to a ventilated place and repaired with special tools. Do not use open flames for lighting. Avoid exposure to the sun and rain during transportation, and handle with care during loading and unloading to prevent the barrel body from collision and deformation. Its properties are stable and if stored properly, there will be no obvious change in quality within three years, so it can be stored safely for a long time.
