Product Description
What Is AEO-2 / AEO-3 / AEO-7 / AEO-9?
AEO-2 / AEO-3 / AEO-7 / AEO-9 are a range of Alcohol Ethoxylates, which are non-ionic surfactants derived from the reaction of fatty alcohols with ethylene oxide (EO). The primary difference between these variants lies in the alkyl chain length (C6, C9, C14, C16) and the number of ethylene oxide (EO) units added, which influences their hydrophilic-lipophilic balance (HLB) and application.
Preparation:
The synthesis of these alcohol ethoxylates involves the following steps:
- Reaction: When an alkaline catalyst, usually NaOH or KOH, is present, fatty alcohol and ethylene oxide (EO) react.
- Process: The reaction occurs at high temperatures and pressures, leading to ethoxylation.
- Purification: To obtain the desired product, the reaction mixture is neutralized and purified by distillation, which eliminates surplus reactants and byproducts.
