Structure and use of methyl allyl alcohol polyoxyethylene ether (HPEG)
Alkylpropanol is an important organic intermediate used in the synthesis of perfumes, resins and the like. The synthesis of methyl allyl alcohol polyoxyethylene ether (HPEG) from methyl allyl alcohol and ethylene oxide is used for a new generation of high performance concrete water reducer.
Methyl allyl alcohol polyoxyethylene ether is easily soluble in water and various organic solvents, and is an important raw material for a new generation of polycarboxylic acid superplasticizer. The polycarboxylate superplasticizer synthesized by using this product has high-efficiency particle dispersing property and retention ability, and has many advantages such as high water-reducing rate, low cement usage, good reinforcing effect, good durability, no corrosion, and environmental friendliness. It can be applied to high-performance, high-strength (C60 or higher) commercial concrete with on-site mixing and long-distance transportation. Water reducing agent is one of the important products in the building materials industry, and it has gradually become an important fifth component in concrete except sand, stone, cement and water. Methyl allyl alcohol (MAO) is an important intermediate used in the synthesis of perfumes and resins. The methyl allyl alcohol polyoxyethylene ether polymerized with methyl allyl alcohol and ethylene oxide (EO) is a polycarboxylic acid water-reducing
A very important macromonomer. The methyl allyl alcohol polyoxyethylene ether is easily soluble in water and various organic solvents, and the synthesized polycarboxylic acid water reducing agent has high-efficiency particle dispersion property and retention ability, and has low dosage, high water reduction and good reinforcing effect. Good durability, non-corrosive steel bars, green environmental protection and many other advantages.
