POLYETHYLENEIMINE
CAS No.9002-98-6
Alias:POLYETHYLENEIMINE, BRANCHED;Aziridine,homopolymer;Ethyleneimine,homopolymer;polyethylenimine(10,000);
Molecular formula：C2H5N
Molecular weight：43.07
Structural formula：
1. Performance and use:
This product is a colorless highly viscous liquid. Soluble in water, ethanol, hygroscopic, insoluble in benzene, acetone. Precipitation occurs when it meets with sulfuric acid with pH lower than 2.4. Aqueous solution is positively charged, and formaldehyde is added to produce coagulation.
Used as wet strength agent for ungummed respiratory paper, retention aid and pulping agent in the process of paper making can reduce the pulping degree of pulp. Improve paper dehydration ability. Increase the dryness of paper by 1%～4%. Increase production capacity by 5%～20%.
1、High adhesion and adsorption of amino acid can react with carboxyl group to generate hydrogen. Amino acid can react with carboxyl group to generate ionic acid. Amino group can react with carbonyl group to form covalent radical. Polyethyleneimine is able to combine with different substances due to its polar group (amino) and hydrophobic group (vinyl) structure. Using these combined binding power, can be widely used in the next, ink, paint, binder and other fields. 2, high cationic polyethyleneimine in water to polymerization of cations, can neutralize and adsorption of all anionic substances, but also can chelate heavy metal ions. With its high cationicity, it can be used in the field of paper water treatment, electroplating solution and dispersant.3. ReactivityPolyethyleneimine can be easily reacted with epoxy, acid, isocyanate compounds and acidic gases due to its highly reactive primary amine and secondary amine. Using this characteristic, it can be used as epoxy resin reactant, aldehyde adsorbent and dye fixing agent.

3. Packaging and storage:
Packaging specification:25kg/bag, also can be determined according to user's need.
During transportation, it is necessary to protect against sunlight, rain, and high temperatures.
The product should be stored in a cool, dark, ventilated place, away from sources of fire.
4.Safety protection:
Pay attention to labor protection when handling it and avoid contact with skin, eyes, etc.After contact, rinse immediately with plenty of water
