Sodium diethyl dithiophosphate is one of the most popular salts out there. It is identified by the formula Na3PS2O2 and is used for a variety of purposes. Generally, sodium diethyl dithiophosphate is supplied as a hydrated solid. However, it is also available as a liquid solution. This colourless compound boasts a variety of properties. It can appear dark due to the impurities that are present in the sodium. Its main use is for facilitating the isolation of molybdenum from ores.

Applications of Sodium Diethyl Dithiophosphate

The thing about sodium diethyl dithiophosphate is that it is an extremely valuable salt that serves a variety of purposes. It is commonly used as a floatation agent for molybdenite mineral concentration. It is referred to as nokes regent during its mineral concentration. The reaction of sodium hydroxide and phosphorus pentasulfide allows the salt to be created. Some of the times, impure reagents have to be used for obtaining the desired mixture of salt and oxidized species.

As for the molybdenite particles, they tend to be hydrophobic and end up becoming hydrophilic when exposed to salt. Thus, the nokes reagent is referred to as depressant as it suppresses the floatation tendency that is common among solids. Understanding how sodium diethyl dithiophosphate works helps explain its uses. It can be difficult to get an idea about just how useful sodium diethyl dithiophosphate can be. However, its applications are practical.

As the material is commercially and technologically important, it is used for floatation processing of complex metallic and metal ores. According to plant usage, it was found that sodium diethyl dithiophosphate exhibits greater floatation rates and selectivity for galena and other precious metals when there are other sulphides. In addition to this, they also have a great environmental, safety, and health profile which makes them a great option for a wide range of uses.

Even though sodium diethyl dithiophosphate did not receive a lot of attention in the past among the floatation research community, things have finally changed as companies are interested in chemistry to find out how the fundamentals work. There are plenty of metal sulphides which work perfectly with sodium diethyl dithiophosphate. It shows just how useful the material. There have also been plenty of studies conducted for better understanding the interactions between sodium diethyl dithiophosphate and other metal sulphides. These reveal that the material can be used for plant practice and laboratory ore floatation. Besides this, the findings from each study have been rationalized. They have been explained to find concepts from the chemistry and the uses of sodium diethyl dithiophosphate. The interactions between different metals and minerals reveal what the material can achieve.

Some of the subtleties of the sodium diethyl dithiophosphate are found through its uses, especially when it comes to collector chemistry. The comparison of different interactions allows for better understanding and use. You can easily identify knowledge gaps by utilizing the sodium.


Since sodium tends to be very reactive, it does not occur in its free state even in the Earth’s crust. Sir Humphry Davy is the first person to prepare sodium in its elemental form during 1807. He applied electrolysis for fusing sodium hydroxide. A number of silicate materials rely on sodium like micas and feldspars. There are plenty of rock salt deposits in different parts of the globe. For instance, there are sodium nitrate deposits that can be commonly found in Peru and Chile. The sea has a sodium content of about 1.05%. It corresponds with the concentration of sodium halides.

The thing about sodium is that it has been identified in ionic and atomic forms in stars including the sun. Meteorites have been analyzed to find that silicate material that is present in silicon has around 4.6 atoms of sodium. What makes sodium unique is the fact that it is lighter than water and can be easily cut using a knife. However, it has to be at room temperature in order to be cut. In addition to this, sodium also easily conducts electricity and heat. It even exhibits a photoelectric effect.

The truth is that sodium tends to be the most popular alkali metal out there. Electrolysis is commonly performed for the production of sodium including sodium diethyl dithiophosphate. The molten sodium chloride undergoes electrolysis for producing the final product. The element is widely available and is not as expensive as other elements. It is used for producing gasoline additives, pharmaceutical products, synthetic rubber, polymers like nylon, and various metals like silicon, titanium, and tantalum. Moreover, it is even used for heat exchange.

Significant Uses

The manufacture of sodium peroxide and sodium cyanide were the two earliest uses of the material. The manufacture of tetraethyl lead requires a huge quantity of sodium diethyl dithiophosphate as it is a gasoline additive. However, the introduction of unleaded gasoline has influenced the market considerably. Similarly, the manufacture of sodium alkyl sulphates requires a substantial amount of sodium as it is the principle ingredient for making synthetic detergents.

In addition to the above, sodium is also used for manufacturing sodium hydride along with sodium borohydride. Besides this, sodium is used for producing dyes as well as dye intermediates. The same is the case for various organic reductions. The polymerization of hydrocarbons and purification of hydrocarbons has a huge impact on organic applications.

As for molten sodium, it is an amazing fluid for heat transfer. Its properties are a coolant which means that the transfer of liquid to metal is fast. Sodium is also extensively used for metallurgy. It is the ultimate reducing agent for producing titanium, zirconium, and calcium along with other transition metals. The commercial production of titanium requires the use of sodium for the reduction of titanium tetrachloride.


Once you have finished reading this post, you will know more about sodium and sodium diethyl dithiophosphate along with its uses. There is no denying that it is a powerful material that offers a ton of uses. Hence, you should contact reagents manufacturers for sodium diethyl dithiophosphate.
