HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid) and HEDP2 sodium (usually referred to as the sodium salt form of HEDP, such as the sodium version of 1-Hydroxyethylidene-1,1-Diphosphonic Acid) have a number of differences in chaical properties and applications. The following are their main differences:

1. Chaical structure

- HEDP: 1-Hydroxyethylidene-1,1-Diphosphonic Acid with the molecular formula C₂H₇O₇P₂. It is an organic acid containing two phosphate groups and exists mainly as a free acid. It has a hydroxyl group and two phosphate groups in its structure.

- HEDP 2Na: It usually refers to the sodium salt form of HEDP, such as the disodium salt of 1-Hydroxyethylidene-1,1-Diphosphonic Acid. Its chaical formula is C₂H₇Na₂O₇P₂. Compared to HEDP free acid, the sodium salt form has sodium ions in the molecule replacing the hydrogen ions of the free acid.

2. Solubility

- HEDP: As a free acid, HEDP usually has low solubility and poor solubility in water, so a pH adjustment is often required to increase its solubility.

- HEDP 2Na: Due to its sodium salt form, sodium HEDP2 usually has good water solubility. The sodium salt form of HEDP is easier to dissolve in water and is suitable for use in a variety of water treatment applications.

3. Uses

- HEDP: As a dispersant and anti-scaling agent, it is commonly used in the chaical industry, water treatment, textile treatment, etc. The acidic form of HEDP is suitable for special applications that require pH adjustment.

- HEDP2Na : Due to its good solubility and stability, sodium HEDP2 is widely used in water treatment, detergents, industrial circulating cooling water systas and other fields. It is commonly used to prevent scale deposition and as an additive for chaical reactions.

4. Stability and treatment

- HEDP: As a free acid form, it needs to pay attention to pH value and corrosivity issues when handling and storing, and usually needs to be stabilized in an acidic environment.

- HEDP2Na: The sodium salt form of HEDP has better stability and is relatively simple to store and handle. Its higher stability in water makes it suitable for use in a variety of water treatment and industrial applications.

5. Environment and safety

- HEDP: During use, the acidic nature of HEDP may have some impact on the environment and needs to be handled properly to minimize the negative impact on the environment.

- HEDP2Na : The sodium salt form of HEDP generally has a low environmental impact and is easy to handle and use. The stability of its sodium salt form makes it easier to treat and raove from the environment.

Summary

The main difference between HEDP and sodium HEDP2 is their chaical form and solubility. HEDP is in the free acid form, which usually requires pH adjustment to improve solubility, while sodium HEDP2 is in the sodium salt form, which provides better water solubility and ease of handling. According to the specific application needs, choosing the right form can achieve better results.

PBTC (2-phosphonobutane-1,2,4-tricarboxylic acid) is an efficient water treatment agent with excellent scale and corrosion inhibition properties. It is in chaical formula C7H11O9P, molecular weight is 270.13, it is a colorless or light yellow transparent liquid with the following characteristics and application scenarios:

1. Chaical stability: PBTC has good thermal stability and stability against hydrolysis, hydrolysis has not been found in water up to 120°C, acid, alkali and oxidizer resistant .

2. Solubility: it can be miscible with water in any proportion, the pH value of 1% aqueous solution is 1, and it can be used as a chelating agent and metal cleaning agent in detergent industry.

3. Safety: The toxicity of PBTC is low, the oral LD50 of 50% aqueous solution of PBTC for rats is more than 6500mg/kg, but it has a moderate irritating effect on the eyes of rabbits, so it needs appropriate protective measures when used.

4. Application field: PBTC is widely used in circulating cooling water systa and oilfield water injection systa corrosion and scale inhibition, especially suitable for compounding with other water treatment agents such as zinc salts, copolymers, etc., and is suitable for high taperature, high hardness, and high alkalinity water quality conditions.

5. Synergistic effect: PBTC has excellent complexing ability with Ca2+, Zn2+, Mg2+ and other ions, and has good synergistic corrosion inhibition with zinc salt and polyphosphate.

6. Environmental impact: PBTC's tolerance to chlorine or chlorine products and trivalent iron ions in water is better than that of other phosphonates, which makes it useful in a variety of water conditions.

7. Production method: The synthesis of PBTC usually involves an addition reaction between phosphite and maleate in the presence of a catalyst, followed by an addition reaction with acrylate, and finally hydrolysis in an acidic medium to obtain the final product .

8. Price Information: The price of PBTC varies according to market conditions, for example, on April 30, 2024, the price of reagent grade PBTC was $77 for a 500G package and $190 for a 25G package .
