CAS NO.	1330-78-5
Molecular Formula	C21H21O4P
Son	368

I. As a Flame Retardant

Trimethylphenyl Phosphate is an effective flame retardant widely used in electronic and electrical rubber components. Its usage typically includes the following steps:

1. Formula Design: Determine the additional amount of Trimethylphenyl Phosphate in the formula based on the required flame retardant effect and material characteristics.
2. Mixing Uniformly: Mix Trimethylphenyl Phosphate with other materials (such as rubber, plastics, etc.) to ensure its uniform distribution within the material.
3. Processing and Molding: Shape the mixed material into the desired product through appropriate processing methods (such as injection molding, extrusion, etc.).
4. Testing and Verification: Conduct flame retardant performance tests on the finished product to ensure it meets the expected flame retardant effect.

II. As a Base Oil for Aviation-Grade High-Pressure Fire-Resistant Oil

Trimethylphenyl Phosphate can also serve as a base oil for aviation-grade high-pressure fire-resistant oil. Its usage is as follows:

1. Formula Preparation: Blend Trimethylphenyl Phosphate with other additives (such as bis(tert-butylphenyl) phenyl phosphate, epoxidized soybean oil lactylate, antioxidants, etc.) in a certain proportion to formulate a mixture that meets the performance requirements of aviation-grade high-pressure fire-resistant oil.
2. Refining Process: Refine the prepared oil to remove impurities and isomers, ensuring its purity and stability.
3. Performance Testing: Conduct performance tests on the refined oil, including chlorine content, acid value, spontaneous ignition point, boiling point, as well as lubricity, anti-wear properties, aging resistance, antifoaming properties, flame resistance, thermal stability, etc., to ensure it meets the standards for aviation-grade high-pressure fire-resistant oil.

III. Precautions

1. Safe Operation: When using Trimethylphenyl Phosphate, strictly adhere to safe operating procedures, wear appropriate protective equipment, and avoid direct contact with skin and eyes.
2. Storage Conditions: Store Trimethylphenyl Phosphate in a cool, ventilated, and dry place, away from fire sources and heat.
3. Environmental Requirements: During use, pay attention to environmental protection and avoid causing pollution to the environment.

In summary, the usage of Trimethylphenyl Phosphate varies depending on its application fields, but it should always adhere to the principles of safety, environmental protection, and efficiency. When using it specifically, adjustments and optimizations should be made according to actual conditions and needs.
