| Trimethyl phosphate is an organic reagent, stable at room temperature, good solubility in various resins, low viscosity, low hue, so it can be used as a special solvent; Epoxy resin additive (reduces viscosity); Anti-coloring agent for polyester fiber processing (improve dyeing quality); Textile oils; Used as gasoline additive, it can prevent knock, improve octane number, and improve the stability of leaded gasoline when stored; It can also be used as a control agent for gasoline surface ignition and a decomposition inhibitor for tetraethyl lead at high temperature. Non-corrosive gasoline additives; Catalyst for polyester fiber polymerization; Graphite products modifier; Plasticizer; Extractant; Pesticide Insecticide raw materials. Trimethyl phosphate hydrolyzes with water, so it must be kept against moisture. Due to the release of PO43- due to its hydrolysis, it becomes a homogeneous precipitator for the formation of insoluble phosphate precipitation, and is often used as a precipitating reagent for zirconium and hafnium and a diffusion source for the determination of semiconductors. In addition, trimethyl phosphate is also a phospholipid extractant, which is used to extract and separate certain metal ions. | |||||||||

1. Performance and use:
Trimethyl phosphate (TMP), the simplest trialkyl ester of phosphoric acid, It is a colourless, nonvolatile liquid. soluble in most organic solvents, low solubility in water. TMP is stable in neutral, acidic or alkaline solutions, and is classified as "not readily biodegradable". Direct photodegradation is not expected because trimethyl phosphate does not absorb UV light.
Trimethyl phosphate is used as an intermediate in organic synthesis. Its industrial applications are much fewer than those of other organic phosphates.Trimethyl phosphate undergoes hydrolysis in contact with water, so it should be stored in a moisture-proof manner. Due to its hydrolysis and release of PO43-, thus becoming a homogeneous precipitant for the formation of insoluble phosphate precipitation, often used as a precipitation reagent for zirconium and hafnium and as a diffusion source for the determination of semiconductors.
In addition, trimethyl phosphate is also a phospholipid extractant for the extraction and separation of certain metal ions.
Trimethyl Phosphate is used as an electrolyte additive in the synthesis of lithium ion batteries. for controlling spark plug fouling, surface ignition and rumble in gasoline engines.
Trimethyl phosphate used as a reagent for determination of zirconium, solvent, extractant and gas chromatography stationary phase.
