Alkoxylation is a term used in chemistry to describe a process that involves adding alkoxy groups to a molecule. There are several synonyms for this term, which include ethoxylation, propoxylation, butoxylation, and methoxylation. These terms refer to the addition of specific alkoxy groups, such as ethoxy (C2H5O-), propoxy (C3H7O-), butoxy (C4H9O-), and methoxy (CH3O-), respectively. Alkoxylation is a widely used process in the manufacturing of various chemicals, including detergents, surfactants, and emulsifiers. The use of different alkoxylation methods and the selection of specific alkoxy groups can alter the properties and performance of the resulting product, making it an essential process in the chemical industry.
