Synthesis method and application of oleic acid-polyethylene polyamine polyether

Abstract

The invention provides a synthesis method and application of oleic acid-polyethylene polyamine polyether. The synthesis method is mainly characterized in that the equation is shown in the specification, wherein z is any integer from 1 to 6, n is any integer from 1 to 20, and m is any integer from 0 to 15. Through the synthesis of an oleic acid-polyethylene polyamine polyether intermediate, the synthesis of oleic acid-polyethylene polyamine polyether and product compounding, the oleic acid goes through an amidation reaction with polyethylene polyamine and then is synthesized through etherification with ethylene oxide and propylene oxide to obtain a functional additive of the cellulose viscose production technology, and the decomposition of sulfonate and deposition of elemental sulfur or sulfide are prevented in the processes of spinning and forming and drafting of Modal viscose, so that the viscose is clear and the filtering property is improved; and moreover, the interfacial tension of the viscose is reduced to prevent blocking of spinneret orifices, the spinning and forming effect is good, and the product quality is stable. The synthesis method has the advantages of simple technology, high product purity, few imidazoline byproducts and good effect.

Description

technical field [0001] The invention relates to an oleic acid polyethylene polyamine polyether functional surfactant used in the production process of modal cellulose fibers and a synthesis method thereof. Background technique [0002] Modal cellulose fiber has the characteristics of good gloss, bright color after dyeing, strong hygroscopicity, cool and breathable, and is very popular among people. However, there are a series of problems in the production process of cellulose pulp, such as difficult filtration, poor spinning formation, unstable quality of finished products, and low production capacity, which affect the normal production to a certain extent. Among them, the modified amine ether surfactant, as a functional additive, can well solve the above problems and play an inestimable role in improving fiber quality. At present, the surfactants similar to oleic acid polyethylene polyamine polyether on the market mainly include oleic acid alkanolamide (Ninal) and oleic ac...

AI Technical Summary

Problems solved by technology

It has a low surface tension. On the basis of polyamine synthesis, etherification is carried out. After industrialization, special effects have been achieved, which solves the problems of sulfur deposition, filtration difficulties, and poor spinning formation in the production process of modal cellulose fibers. A series of problems such as poor quality of finished products, so that the softness and draft rate of fibers can reach higher indicators; promote the smooth production of modal fibers, and at the same time develop and enrich amine-based surfactants, and become the industry leader of polyamine-based surfactants development provides a better basis and opens up a whole new kind of application
