What chemical is THPS?

Chemical Name and Formula

When you ask about THPS, it means tetrakis(hydroxymethyl)phosphonium sulfate. The name is long, but it shows the structure. THPS is an organophosphorus compound. Its formula is C₈H₂₄O₁₂P₂S. You can check the table below for more details:

This chemical has phosphorus, sulfur, oxygen, carbon, and hydrogen. People use it in water treatment and factories.

Physical and Chemical Properties

You might wonder why THPS is so helpful. THPS is a clear, colorless, thick liquid. Its density is about 1.4 g/mL at room temperature. It mixes well with water. Here are some key physical properties:

THPS stays stable most of the time. You should keep it away from strong oxidizers and alkalis. It can react with those chemicals. The structure has a phosphonium cation with four hydroxymethyl groups and a sulfate anion. This helps it mix with water and work as a strong biocide. THPS breaks down fast in the environment. It does not build up or cause harm. Many people pick it because it is not very toxic and breaks down easily.

Tip: If you need a biocide that works quickly and does not leave much residue, THPS is a good choice.

How THPS is Made

You may wonder how THPS is made. Making THPS takes a few steps:

1. Raw material preparation

• You start with phosphine gas (PH₃), formaldehyde (HCHO), and sulfuric acid (H₂SO₄).

2. Reaction process

• First, phosphine reacts with formaldehyde in an alkaline setting. This makes tetrahydroxymethyl phosphonium salt.

• Then, you add sulfuric acid. This step turns the salt into THPS.

3. Purification

• The mixture goes through crystallization, filtration, washing, and drying. These steps help get pure THPS.

4. Packaging and storage

• THPS is stored in water at about 75% strength. Use containers that do not rust to keep it safe.

When you learn about THPS, you see it is made with care. The process uses common chemicals and careful steps. This makes a safe and useful biocide.

Uses of THPS

Water Treatment Applications

THPS is used a lot in water treatment plants. It kills bacteria, fungi, and algae in water. You only need a small amount for it to work. This means less waste and a safer place for everyone. The table below shows how well THPS works at different amounts:

Even at low doses, THPS works very well. It is better than many older chemicals. THPS breaks down fast and does not hurt nature. The US EPA says it is not very toxic and breaks down easily. You can use it safely in many water systems.

Note: THPS helps keep water clean and safe with less harm to the earth.

Oil Field and Industrial Uses

THPS is used in oil fields and factories. It controls bacteria in water, pipes, and tanks. Here are some main ways it is used in oil fields:

1. It stops bacteria from making oilfield water go bad.

2. It helps stop rust in pipes and tanks by fighting bacteria.

3. It helps get more oil by controlling germs during oil recovery.

4. It keeps fluids clean during hydraulic fracturing.

5. It treats water that comes back from wells to keep it clean.

6. It stops bacteria in drilling muds and protects equipment.

7. It helps meet rules because it is less toxic than old chemicals.

THPS is also used in other industries. The table below shows some examples:

Industrial Sector	Purpose
Leather Industry	Biocide, tanning agent
Textile Industry	Flame retardant
Paper Pulp Industry	Biocide

Paper-Making and Other Uses

THPS is used in paper mills to stop slime and keep machines working. It controls bacteria and fungi in water systems. When you use THPS, you get cleaner paper and fewer machine problems. It also helps keep the mill cleaner. THPS is better for the earth because it breaks down and is not very toxic.

You also find THPS in cooling water, wastewater, fish farms, and city water treatment. Scientists keep finding new ways to use THPS. You get safer, better, and greener solutions with it.

Tip: If you want a biocide that works well and helps the planet, THPS is a good pick.

Why It Matters

Effectiveness as a Biocide

You want a biocide that works fast and keeps water safe. THPS is good because it attacks bacteria, algae, and fungi. It does this by breaking their cell walls. Using 160 ppm of THPS can make carbon steel lose 85% more weight when exposed to Pseudomonas aeruginosa. This means THPS can stop bacteria and protect machines from damage. You only need a little THPS to stop germs in water. For example:

• The minimum inhibitory concentration (MIC) of THPS for Pseudomonas aeruginosa is 320 µg/ml.

THPS works in many places, like water plants and oil fields. It gives strong protection against germs without harsh chemicals. If you ask, "What keeps water clean and safe?" THPS is often the answer.

THPS helps you control bacteria and protect equipment with less risk to people and the environment.

Environmental and Health Benefits

You care about safety and the planet. THPS has more benefits than older biocides. It breaks down fast and does not build up in nature. Here is how THPS acts in water:

THPS is less toxic to people and animals in water. You get these good things:

• THPS is easy to break down, so it is better for the earth.

• It turns into trishydroxymethyl phosphine oxide, which is less toxic.

• Using THPS means less leftover chemicals, so water is safer for people and animals.

Some people worry about THPS and animals. You may hear that THPS hurts wildlife or pollutes water. Many experts say THPS is not as bad as some think. People who use THPS want to show they help nature, not hurt it.

If you want a biocide that works well and supports a cleaner world, THPS is a smart choice.
