    摘要： The synthesis of polyhydroxy fatty acid amide surfactants exemplified by the compound C.sub.11 H.sub.23 C(O)N(CH.sub.3)CH.sub.2 [CHOH].sub.4 CH.sub.2 OH by reacting a fatty acid ester with an N-alkyl sugar amine can result in contamination of the product surfactant by residual sources of fatty acids. These residual fatty acids may be unacceptable in high sudsing detergent compositions, such as dishwashing liquids, especially with Ca or Mg cations. The process of this invention reacts such contaminants with alkyl amines or, especially, ethanolamine, to convert them into fatty alkyl- or alkanolamides, which are quite acceptable in fully-formulated detergent compositions for home or industrial use.
