Polyethyleneglycol (PEG) Non-ionic surface-active agent CAS: 25322-68-3
Ethoxylated fatty alcohols C16-C18 Non-ionic surface-active agent CAS: 68439-49-6
Ethoxylated fatty alcohols C12-C14 Non-ionic surface-active agent CAS: 68213-23-0
Ethanolamines 85% mixture of ethanolamines CAS: 141-43-5 Ethanolamines are used in purification processes in the preparation of pure carbon dioxide, in the textile and cement industries. Ethanolamine is also a raw material in the chemical and petrochemical industry. Under normal conditions ethanolamines are not subject of polymerization, oxidation, hydrolysis or degradation. Monoethanolamine and triethanolamine are easily soluble in water and alcohol. Diethanolamine is soluble in alcohol and poor soluble in water. All ethanolamines absorb CO from the atmosphere, react with fatty acids, creating soaps, esters, amides, and their reactivity ability decreases from monoethanolamine to triethanolamine.
Demulsifiers Block-copolymers of ethylene oxide and propylene oxide PM-series Demulsifiers are used for dehydration and desalting of oil in oil production and refining by means of thermal and electric dehydration. The required dosage depends on the stability of emulsions, process temperature, water separation time and the expected result. Optimal application of demulsifiers is defined upon test results of fresh emulsion. PM-series Demulsifiers in a wide concentration range do not cause an increase of petroleum products conversion in wastewater.
Methoxy-polyethyleneglycol (MPEG) Surfactant based on ethylene oxide and methanol CAS: 9004-74-4 MPEG is used in the production of superplasticizers for concrete.
