Progress of technology for tertiary fatty amine preparation

The progress in field of research work and development for preparation of tertiary fatty amines were summarized from three aspects. The marketing and main applications of tertiary amines were introduced, mainly for preparation of cationic surfactants and amphoteric surfactants as important intermediates. The main varieties of these two types of surfactants can be used as active ingredient of disinfectants, corrosion inhibitors, antistatic agents, fabric finishing agents, and personal care products, etc. The preparation process of fatty tertiary amines was emphatically described. The critical technology of this process is the preparation of catalysts, including screening of various components of the catalyst and its preparation conditions. At present, the multiple metallic composite catalyst are mainly adopted, with copper as the main active matter to blend with other metallic elements. A brief review of the development of the technology for catalytic amination of fatty alcohols was included, and the suggestion for the further development of preparation technology of tertiary amines was mentioned, i.e. to strengthen the basic theoretical research, to improve the industrialized technology under the guidance of basic theory, especially for technological conditions of the catalyst preparation.
