Polyethylene polyamine is a co product of Ethylenediamine, Diethylenetriamine, triethylenetetramine and tetraethylenepentamine. It is a yellow or orange red transparent viscous liquid with an ammonia odor. Easily absorbs moisture and carbon dioxide from the air. Salt corresponding to acid formation will solidify at low temperatures. It is strongly alkaline. It can be miscible with water, alcohol, and ether. Corrosive. Its characteristic lies in the simultaneous presence of amino groups, polyoxyethylene (or polyoxypropylene), organosilicon oxygen, and multi arm structures in the molecular chain, which combines their excellent performance and has good surface activity and temperature resistance characteristics. Mainly used for preparing crude oil demulsifiers, sewage treatment agents, pesticide dispersants, and daily necessities additives.
