Outlook on Organic Phosphonate Corrosion and Scale Inhibitors

Since the development of organic phosphine water treatment agent HEDP in foreign countries in the 1960s, organic phosphine salt water treatment agents have undergone generations of development. The first generation organic phosphonic acid salt water treatment agents HEDP and ATMP, as corrosion and scale inhibitors, dominated phosphorus based formulations for nearly 20 years until the late 1970s, when PBTC emerged to meet the needs of high concentration ratios. Subsequently, with the emergence of HPA in the mid-1980s, it formed the expected all organic water treatment agent that could compete with metal ion formulations. In the 1990s, there was further development of organic phosphonic acid salt water treatment agents, with products represented by polyamino polyether methylphosphonic acid (PAPEMP) and POCA. Its main feature was the increase in molecular size, leading to the emergence of large molecule organic phosphonic acid salt water treatment agents. Since the early 1990s, the demand for organic phosphates has continued to grow and will continue to maintain the current situation for a long time to come. Many water treatment companies are developing new types of organic phosphates, such as introducing sulfonic acid groups into organic phosphate molecules, which presents an optimistic prospect for organic phosphates. Therefore, the introduction of macromolecular organic phosphonates, efficient and low phosphorus content organic phosphonates, and sulfonic acid groups as efficient and multifunctional organic phosphonates has become a hot topic in the research and development of industrial water treatment agents.

Which polymers have good scale inhibition effects when combined with edtmpa

EDTMPA belongs to organic phosphoric acid and is a highly efficient polar corrosion inhibitor solvent that can dissolve and has strong chelating force. When used alone, its effect is already good, and it can also cooperate with some non-ionic and anionic polymers to increase its surface activity and permeability. It is recommended to mix it with PAAS (sodium polyacrylate), HPMA (hydrolyzed polymaleic anhydride, ultra-high heat resistance above 300 degrees) or PASP (sodium polyaspartic acid, strong anti settling effect on calcium and barium salts, good descaling effect). Please refer to it as appropriate. In addition, my suggestions can only be used for water treatment, and may not be suitable for solvents or strong acid-base aqueous solutions. If it is in these environments, please provide specific explanations.To learn more about EDTMPA information, you can consult as follows:

Will methanol prices hit historical lows again?

Methanol as one of the important raw materials for water treatment chemicals (hedp),Since October 2022, the price of methanol in China has been continuously declining. As of the end of May 2023, the benchmark market price of methanol in China has reached 2280 yuan/ton, and the closing price of the futures market has dropped below 2100 yuan/ton, setting a recent low point. The continuously declining methanol market price has led to significant fluctuations in the methanol industry chain market. To what extent will the methanol market price drop? Will the methanol market once again hit historical lows?

According to relevant data, as of the end of May 2023, the Chinese methanol market has experienced a consecutive 10 month decline, with the lowest price reaching 2100 yuan/ton. From 2011 to May 2023, the price trend shows that the lowest prices in history occurred in January 2016 and August 2020, with the lowest prices being around 1650 yuan/ton. The current price of 2100 yuan/ton is the lowest price in the past 10 months and also the lowest point of weak fluctuations after the price rebound in 2020.

From the price trend of the past 12 years, although the current methanol market price in China has not reached a historical low, it has also basically fallen below the average price of the past 12 years. According to statistics from Pingtouge, the average price of methanol benchmark in China in the past 12 years has been 2440 yuan/ton, which is the average price of the past 12 years. However, the current price has fallen below the average price of the past 12 years, indicating that the current price has fallen below the support of historical average prices.

The main reason for the 10 consecutive months of decline in the Chinese methanol market is due to the weak volatility of the crude oil market, which has had a negative impact on bulk chemicals. Crude oil is one of the main reasons for the long-term decline in the methanol market. On the other hand, there has been a long-standing supply-demand contradiction in the Chinese methanol market, with high port inventory and high operating load of domestic production enterprises, resulting in a consistently high supply pressure in the Chinese market this year. This is the reason for the continuous decline in prices in the Chinese methanol market. On three aspects, the continued weakness of the international market has had a negative impact on the Chinese market. In four aspects, the demand in the downstream consumer market is sluggish, such as the continuous downturn in formaldehyde consumption, which is transmitted to the methanol market through the latitude of the industrial chain.

The above is an analysis of the market reasons for the price decline in China’s methanol market. Many information companies have conducted detailed and multiple analyses, and we will not do too much analysis here. What is currently more concerning in the industry is the extent of this decline? Can we reach a historical low of 1650 yuan/ton?

Firstly, let’s analyze the market price trends of methanol in China from April to June of previous years? In order to represent the price fluctuation range, Pingtou Ge calculated the year-on-year change rate of monthly prices over the past 10 years (i.e. the fluctuation rate of the current month’s prices compared to the previous year’s current month’s prices). Pingtou Brother believes that a clear seasonal pattern can be observed through the year-on-year change rate of monthly average prices.

Methanol, as a flammable liquid, increases in temperature and the risk of storage. Many companies have reduced their inventory to cope with high temperatures, which invisibly reduces the effective space for storage and provides storage pressure for price drops. So, if prices have dropped year-on-year in the summer of previous years, it can also confirm this logic.

Based on the year-on-year change rate of prices from April to June in the past 10 years, there have been 6 years of year-on-year decline and 4 years of year-on-year increase. And in the years of decline, there was a decline from April to June. So, if methanol has strong seasonality, there is a high probability of a year-on-year decline from April to June 2023.

From this analytical perspective, there is still a significant possibility of a decline in the methanol market price in the future, which is expected to fall to around June.

The difference between HEDP and HEDP4 sodium

HEDP (1-hydroxyethylphosphonic acid) and HEDP4 sodium (phosphate 1-hydroxyethyl-1,1-diphosphonic acid tetrasodium salt) are two different chemical substances, although they have similar names, there are some differences in structure and properties.
Chemical structure: HEDP is an organic phosphate that contains a hydroxyethyl group and a phosphonic acid group in its chemical structure. And HEDP4 sodium is the sodium salt form of HEDP, which contains four sodium ions and forms a salt structure with HEDP.
Solubility: The solubility of HEDP and HEDP4 sodium is different. HEDP is more soluble in water, while HEDP4 sodium may have a higher solubility due to its salt structure.
Usage: HEDP is commonly used as a water treatment agent, corrosion inhibitor, and scale inhibitor, and is widely used in industrial water treatment fields, such as cooling water systems, boiler water systems, etc. And HEDP4 sodium is mainly used in fields such as cleaning agents, rust inhibitors, and metal surface treatment agents.
PH stability: Due to its salt form, HEDP4 sodium may have better stability under acidic conditions compared to HEDP.
It should be noted that since HEDP and HEDP4 sodium are both chemical substances, correct operating procedures and safety regulations should be followed before use. In practical applications, the specific selection of which chemical substance to use should be evaluated and selected based on specific needs and circumstances.
