Fatty group end-amino polyether production method and special catalyzer preparation method

Abstract

The invention discloses a fatty group end-amino polyether production method and special catalyzer preparation method, wherein the catalyst is special-purposed frame nickel catalyst, the custom made alloy is dissolved completely by sodium-hydroxide liquor under finite temperature and proportioning conditions, then distilled water is used for scouring to neutrality, then anhydrous alcohol is used for washing and sealing. The process for preparing the end-amino polyether comprises using the said special-purpose catalyst for reaction under finite concentration, temperature and proportioning conditions, thus the end-amino polyester can be obtained.wh

Description

1. Technical field

[0001] The present invention relates to a compound, in particular to a class of polyoxyalkylene compounds terminated by primary amino groups. 2. Background technology

[0002] Amine-Terminated Polyether (ATPE for short) is a kind of polyoxyalkylene compound terminated by primary or secondary amino groups. Because the terminal amino group of the macromolecular chain contains active hydrogen, it can react with isocyanate groups and epoxy groups. Therefore, in recent years, ATPE is mainly used as a synthetic raw material for polyurethane (polyurea) materials and as a curing agent for epoxy resins. In addition, ATPE can also be used as anti-turbidity and anti-sedimentation additives in engine fuel oil.

[0003] According to the structure of the hydrocarbon group connected to the amino group, ATPE can be divided into two types: aromatic and aliphatic; according to the number of hydrogen atoms in the amino group, it can be divided into primary amino group and s...
