What are the requirements for the reaction environment when preparing Tris (1-chloro-2-propyl) Phosphate TCPP?
This product is made of phosphoric acid and 1-chloro-2-propanol. It needs to be operated in a dry environment. If the humidity exceeds 60%, the reaction will be slow. Put phosphoric acid in an enameled reactor, add 1-chloro-2-propanol in a ratio of 1:3, add aluminum chloride as a catalyst, heat to 110 degrees, esterify the two, generate water and Tris (1-chloro-2-propyl) Phosphate TCPP, recover the excess alcohol through a condenser, and continue the reaction for four hours. The process is like making medicine. If the humidity is too high, the catalyst will be deactivated. Therefore, a calcium chloride drying tank must be placed next to the reactor to ensure that the reaction environment is dry, so that TCPP with excellent purity can be obtained, with a light yellow color and no turbidity.
Why does Tris (1-chloro-2-propyl) Phosphate TCPP have excellent flame retardant effect?
This product contains two flame retardant elements, phosphorus and chlorine, which have a synergistic effect and a flame retardant efficiency far exceeding that of single element flame retardants. When added to polyurethane foam, a dosage of 10% can reach UL94 V-0 level. When burning, the chlorine element releases hydrogen chloride to inhibit free radical reactions, and the phosphorus element generates a phosphate protective layer to block oxygen and insulate heat. The dual effects quickly extinguish the flame. In soft polyvinyl chloride, it can both flame retardant and plasticize, increasing the oxygen index of the product from 21% to 30%, and the smoke density is low when burning, which is more environmentally friendly than brominated flame retardants.
What are the applications of Tris (1-chloro-2-propyl) Phosphate TCPP in building materials?
This product is the first choice for flame retardants for thermal insulation materials. When added to extruded boards, the boards can reach the B1 flame retardant standard, and will not drip or spread when exposed to fire. It is used for curtain fabric impregnation treatment, which can make the fabrics washable fifty times and still maintain flame retardancy, and the afterburning time is less than two seconds. In floor glue, it has good compatibility with resin. After adding, it does not affect the bonding force, making the floor soft and fireproof. It is suitable for crowded places such as shopping malls and hospitals. It has low volatility and is retained in building materials for a long time. The flame retardant effect does not decay over time, so it is relied on for building safety.
What is the chemical stability of Tris (1-chloro-2-propyl) Phosphate TCPP?
This product is stable at room temperature and is not easy to decompose when it encounters weak acids and weak bases. It can be stored for a long time within the pH range of 4-9. It starts to decompose at high temperatures of 250 degrees, releasing chlorides and phosphorus oxides, so the processing temperature should not exceed 220 degrees. It is safe with metals and does not corrode iron, copper, aluminum and other utensils. It can be stored in iron barrels. However, it is easy to dechlorinate when encountering strong reducing agents, so it should not be stored with zinc powder and iron powder to prevent chemical reactions. Its aqueous solution is neutral, has little irritation to the skin, and does not require special protection during operation. It is safer than bromine-containing flame retardants.
What are the differences between the application scenarios of Tris (1-chloro-2-propyl) Phosphate TCPP and TOP?
Tris (1-chloro-2-propyl) Phosphate TCPP focuses on flame retardancy and is widely used in fire-resistant scenarios such as building materials and furniture; Trioctyl Phosphate TOP is good at lubrication and plasticization, and is suitable for mechanical lubricants and plasticizers. In terms of compatibility, TCPP has good affinity with polyurethane and epoxy resin, while TOP is more suitable for polyvinyl chloride and polyethylene. From the perspective of environmental protection requirements, although TCPP contains chlorine, it complies with the RoHS standard, and TOP is halogen-free and more suitable for food contact materials. The two have their own strengths and can be selected according to needs.
