Abstract
The present invention generally relates to a process for preparing alkoxylated alkylamines and/or alkyl ether amines. The process consists of two stages and utilizes a catalyst with a multiple-charge counterion. The alkoxylated alkylamines and alkoxylated alkyl ether amines prepared by the process possess the peaked ethoxylation distribution and contain less hazardous by-product.
