Product Information
优点
Genamin M41/2000 offers the following properties:
Genamin M41/2000 shows chemical reactions typical for primary amines like formation of:
- very good soluble in cold or hot water and in many organic solvents like isopropanol or acetone
- slowly absorbs carbon dioxide from air and water from humid air
- the amino group reacts faster and forms more stable compounds than the hydroxyl group of the corresponding polyether alcohol
Genamin M41/2000 shows chemical reactions typical for primary amines like formation of:
- ammonium salts (pH dependent) with inorganic or organic acids,
- amides with carboxylic acids, anhydrides or esters,
- urea derivatives with isocyanates uncatalyzed at room temperature,
- aminoalcohols with epoxides,
- imines with aldehydes or ketones.
