Hydrofluoric Acid (HF) with 60% Purity
Application:
The first category: hydrogen fluoride with a purity of more than 99% and named AHF, which is in a gaseous state and due to its high purity, has the following special
applications:
* HF gas is used to separate uranium isotopes.
* HF gas acts as a catalyst in the oil and petrochemical industry.
* HF gas is mainly used in the production of aluminum, chlorofluorocarbons and polytetrafluoroethylene.
* HF gas is used in the production of semiconductors to remove oxides from the surface of silicon wafers. The second category: HF (hydrofluoric acid) solution with a purity of 60%, which is in the form of a liquid solution, and due to its low purity, it has the following
different uses:
* It is used in the steel industry to polish stainless steels: because it has the ability to react with metal oxides.
* It is also used as a glass solvent in laboratories.
* It is used in the production of hexafluorine and silicic acid (H2SiF6).
* In the production of potassium hydrogen fluoride as a mattifying agent and as a starting material in the production of elemental fluorine.
* It is used in the production of hexafluoride and silicates, such as hexafluoride and silicate of magnesium, zinc and copper, which are easily dissolved in water. In addition, they are mainly used as preservatives in wood protection.
* Sodium hexafluorosilicate is used in water fluoridation.
* Boron trifluoride is obtained from the reaction of hydrogen fluoride and boric acid in the presence of sulfuric acid, which is sold in pressurized gas cylinders. This substance is used as a complex or additive compounds (for example, with ethers, alcohols, carboxylic acids, etc.) or in pure form as a Friedel-Crafts catalyst.
* Tetrafluoroboric acid, which is produced as a 50% aqueous solution of boric acid and hydrofluoric acid, and other fluorine and alkaline borates, ammonium, and transition metals are used in the galvanic layer of metals, as a melting agent, straw ignition, etc.
* It is used in electrochemical fluorination of organic compounds. In this method, fluorine compounds are obtained by electrolysis of the corresponding non-fluorine compounds in liquid hydrogen fluoride. They are used in herbicides, straw combustibles such as C4F9SO3K, repellents and grease for textiles, fire extinguishers, emulsifiers for tetrafluoroethylene polymerization, flow control agents and dripping colors, hardening agents, catalysts and membranes.
* In the production of polyvinyl fluoride (PVF), the combination of acetylene and hydrofluoric acid and the polymerization of the obtained vinyl fluoride are used, which causes the parts to be covered against water.
Product Introduction:
Hydrofluoric acid (HF) is a weak acid from the group of hydrohalic acids, and therefore it is molecularly soluble in water.
This acid has a colorless appearance with a very sharp and harsh aroma, which has the ability to dissolve many substances and is considered a unique compound in dissolving oxides (oxygenated compounds). Hydrofluoric acid can dissolve glass, that’s why plastic containers are used to store it. It should be noted that the use of acid with a concentration of 60% is more common due to its efficiency and stability (less acid vapors).
Technical Specifications:
The production process is as follows:
* Production of HF gas from the reaction of 98% sulfuric acid with calcium fluoride soil at a temperature of 250 to 270 °C.
* Removing dust particles and cooling HF gas
* Absorption of HF gas by the water inside the filled tower
* Finally, the produced HF reaches the desired concentration. It is the concentration of acid that can be packaged and as a result, its transportation will be simpler and safer.
Advantages:
* High Quality
* High production volume
* Reasonable price
