Tetrakis Hydroxymethyl Phosphonium Sulphate (THPS) Ultimate Usage Guide 2021


Tetrakis(hydroxymethyl)phosphonium sulfatephosphonium_chloride “Tetrakis(hydroxymethyl)phosphonium sulfate“) is an environmentally friendly biocide. It is mainly used in water treatment systems, oil drilling work, and the paper industry.THPS chemicals are widely used. Customers still have questions about the use process. The following is the introduction of tetrahydroxymethyl phosphonium sulfate addition in 2021.

Q1.The shelflife of tetrahydroxymethylammonium sulfate.

(1) Is THPS solution easily oxidized by air?
(2) How long does it take for the whole bottle to expire when the cap is generally open and ready for use

Tetrahydroxymethylammonium phosphate sulfate, abbreviated as THPS or thps chemical., is a new type of spectroscopic fungicide.

The thps biocide suppliers state that it is chemically stable. However, it’s an antioxidant. After use, THPS can be quickly decomposed into non-toxic and non-side effect decomposition products.

This shows that it is a relatively strong reducing agent. As a precaution, THPS must be stored away from light, at room temperature, with the lid on. If there is no text indicating the expiration date, you can only judge it by its effect.

Q2.Kathon (MIT/CMIT) and THPS can be used for water treatment sterilization. Can they be mixed?

Answer: Kathon is a mixture of MIT/CMIT. It is compatible with anionic, cationic, nonionic, various ionic emulsifiers and proteins. Best used with quaternary ammonium salts. This product can be used simultaneously with oxidizing fungicides.

Q3.Do the following chemicals react with tetrahydroxymethylammonium phosphate sulfate?

Will THPS react with the following two substances when boiled under weak acid conditions?
(1) Sodium sulfite (Hint: Boiling under weak acid conditions releases sulfur dioxide)
(2) Hexamethylenetetramine (Urotropine) (Hint: Urotropine releases formaldehyde when boiled under soft acid conditions)
It seems to be different.
Tetrahydroxymethyl sulfate processing is produced as a permanent flame retardant for cotton fabrics. It was later discovered that there are biocides that are very environmentally friendly.

THPS chemicals can kill microorganisms such as algae in the water. It is a new water treatment agent that is not harmful to the environment.

According to the structural characteristics of tetrahydroxymethylammonium phosphate sulfate, hydrolysis produces phosphoric acid and methanol, and the aqueous solution is acidic. It has reducing properties and is relatively stable. From these aspects, there is no reaction of concern with the above two substances.

Q4.Basic chemical properties of phosphorus tetramethyl alcohol sulfate.

Water treatment agent phosphorus tetramethylsulfate is found to decompose rapidly into entirely harmless substances immediately after use. Containers should be sealed during storage. Store separately from oxidizers and acids.
(1) What is “use”? Will it decompose when diluted with water or light?
(2) Does THPS efficiently react chemically with oxidizers and acids?

Answer:Tetrakis(hydroxymethyl) phosphate.
Tetrakis hydroxymethyl phosphonium sulfate is a cationic surfactant. Its structure is similar to that of neostigmine (quaternary ammonium salt). The principle of water treatment is the adsorption of particles in water for precipitation. The water is generally loaded with soil particles and impurity sols. Cationic surfactants effectively precipitate and purify the water.

“Use,” of course, means that the THPS fungicide into the water to purify the water. Tetrahydroxymethylammonium phosphate sulfate is highly reductive. It can be oxidized by air after contacting water or seeing the light Easily reacts with oxidizing agents to form phosphates. Acid can change its structure and lose its positive charge and become ineffective.

Q5.Uses of tetrahydroxymethylammonium phosphate sulfate.

The amount of tetrahydroxymethylammonium phosphate sulfate in water disinfection is 0.1ml/L. It is introduced online to be added to oxidize air after contacting water or seeing the light.

How long does the disinfection activity last?

THPS is up to 75%. It is itself an aqueous solution. In the online introduction and water contact or see the light than air oxidation, the industry said the shelf life is long (several years).

The answer is this.
THPS aqueous solution in the package is not easy to deteriorate. What makes it deteriorate is the air’s oxygen, and its role is to accelerate the oxidation. Tetrahydroxymethylammonium phosphate sulfate has a single bond of carbon and phosphorus. This bond is readily oxidized by oxygen. If there is no oxygen in the environment, it is still relatively stable.

Tetrahydroxymethylammonium phosphate sulfate decomposes rapidly after use, and the disinfection activity is maintained for a short time. Keep the water disinfection dilution solution.

Q6. What can tetrahydroxymethyl phosphonium sulfate be mixed with?

THPS fungicide mainly kills bacteria and algae in the water but also kills fungi. What kind of compound can I add?

The answer is.

Tetrakis hydroxymethyl sulfate added belongs to quaternary ammonium salt. It is a new type of environmentally friendly biocide. The industry is collectively known as THPS. you say “mix,” the industry collectively known as “compound.”

Fungicides biocides are usually mixed with fungicides to kill bacteria. Many organosulfur compound fungicides are related to fungi and mucilage. In particular, the role of sulfate recovery bacteria is enormous. Among the organosulfur compound, fungicides, dithiocyanomethane, and allicin (thiol compounds) are widely used in China.

Q7.THPS biocides for industrial water treatment?

Tetrahydroxymethyl phosphonium sulfate (THPS) is particularly effective against sulfate-reducing bacteria (SRB), which are often a problem in operations to improve oil harvesting rates, such as water injection treatment, topsides systems, pipeline protection, and storage. THPS kills microorganisms, reduces hydrogen sulfide concentration, and dissolves iron sulfide. It can be used in acidic and alkaline environments.

Thps biocide is a cationic surfactant (similar to a quaternary ammonium salt). It works best with pine. The sulfur in tetrahydroxymethylammonium phosphate sulfate is a sulfate. Sulfur cannot be used in sulfur-containing cooling water systems is S2-, sulfite ions or sulfur-containing organics.
