2-Propylaminoethylamine; 2-(N-Propylamino)Ethylamine; Ethylenediamine, N-Propyl-; N-Propyl-1,2-Ethanediamine; N-Propylethane-1,2-Diamine; N-Propylethylenediamine; PSA; Primary Secondary Amine
Brief Introduction
N-propyl ethylenediamine solid-phase adsorbent is a similar adsorbent to NH2. PSA has two amino groups with pKa values of 10.1 and 10.9, respectively. It has stronger ion exchange capacity than amino column. At the same time, PSA can chelate with metal ions for extraction of metal ions. Widely used in the treatment of plant pesticide residue analysis samples to remove organic acids, pigments and metal ions

Cationic Starch
Brief Introduction
Cationic starch belongs to chemically modified starch, which is prepared by the reaction of cationic etherifying agent with starch under alkaline conditions. It is a starch ether derivative containing amino group and positive charge on nitrogen molecule produced by etherification reaction between various organic amine compounds containing halogen group or epoxy group and hydroxyl group in starch molecule. Cationic starch mainly includes tertiary amine salts and quaternary ammonium salts. Its raw materials are widely distributed in nature, such as corn, potato, cassava and wheat. Because cationic starch has positive charge and is easy to combine with negatively charged fine fibers, it has many characteristics that raw starch does not have, such as paste stability, water solubility, film-forming, transparency and so on, which makes cationic starch have great uses. In addition, cationic starch has the characteristics of low gelatinization temperature, easy dispersion, high viscosity and good thermal stability.
