Synonym: Mayoquest 2200

PAPEMP production process consists of 4 steps.

  1. Phosphorus acid is input into the reactor and its pH is adjusted by HCl.
  2. Polyetheramine is instilled and the reaction starts while the reactor is heated.
  3. Formaldehyde is input a few hours later.
  4. The reactor will be further heated and steamed for more hours.

Molecular weight: about 600

Structural Formula:

PAPEMP

Properties:

PAPEMP performs excellently in the condition of high hardness and pH as a new antiscalant and corrosion inhibitor. With high calcium tolerance, PAPEMP scale inhibition ability is also high, particularly for CaCO3, CaPO4, and CaSO4. It also effectively restrain Si scale from a formation and stabilize the ions. Such as Mn, and Fe to form chelating compounds.

PAPEMP also have the good tolerance to high temperature, high turbidity, high salt concentration, and high chlorine (Cl and Br) concentration. Sometimes it is built with a polycarboxylic acid. It can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system in situations of high hardness, high alkali, and high pH value.

PAPEMP can be used as a scale inhibitor for reverse osmosis system and multistep flash vaporization system.

Usage:

The good adaption to different situation enables PAPEMP widely used in boiler, cooling water system and oilfield reinjection water as antiscalant and corrosion inhibitor.  For the same reason, PAPEMP is also applied in RO and multistep flash system. Recommend dosage is 5-100 ml/L. Unlike other organophosphonates, there is no optimum dosage for it. Higher the dosage, better the effect.

Besides, PAPEMP works as a nutrient absorber in agriculture. It can also replace those more expensive color transfer inhibitor (eg. yellow turnback inhibitor) like EDTA, NTA and DTPA in textile dyeing.
