Description

technical field

[0001] The invention relates to a preparation method of isomerized alcohol polyoxypropylene polyoxyethylene ether, which belongs to the technical field of synthesis of nonionic surfactants in organic chemistry. Background technique

[0002] Isomerized alcohol polyoxyethylene ether not only maintains the excellent performance of alkylphenol polyoxyethylene ether surfactants (NP, OP), but also has the high degradability of fatty alcohol polyoxyethylene ether surfactants (AEO) , is a new type of surfactant product with both excellent performance and high biodegradability. Isomerized alcohol polyoxyethylene ethers are environmentally friendly, highly degradable, excellent emulsifying properties, excellent cleaning properties, stable performance in neutral, acidic and alkaline environments, and have a wide range of applications. Because isomeric alcohol polyoxyethylene ether has the characteristics of high foam and easy to freeze in winter, it limits its use in s...
