Oct 20, 2016· The invention relates to a process for production of polyurethane systems by reacting at least one polyol component with at least one isocyanate component in the presence of one or more catalysts for the isocyanate-polyol and/or isocyanate-water reactions and/or the trimerization of isocyanate, wherein said reacting is carried out in the presence of pentaethylenehexamine, and also …


Sep 20, 2012· In rare cases the reaction of two components (even though non-hazardous, from temperature or pressure considerations) may produce a product which is significantly more flammable or toxic than the original materials. Although no examples of such a reaction are known at this time, they would be considered hazardous.

Hexamethylenetetramine - Wikipedia

Hexamethylenetetramine or methenamine, also known as hexamine or urotropin, is a heterocyclic organic compound with the formula (CH 2) 6 N 4.This white crystalline compound is highly soluble in water and polar organic solvents. It has a cage-like structure similar to adamantane.It is useful in the synthesis of other chemical compounds, e.g., plastics, pharmaceuticals, rubber additives.

Pentaethylenehexamine -

PRODUCT USE The material is produced by the reaction of aqueous ammonia with 1,2-dichloroethane. This process yields the entire family of ethyleneamines: ethylenediamine, piperazine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, pentaethylenehexamine and aminoethylpiperazine.

The reaction mixture was heated to 160 . o. C and kept at this temperature for 24 hrs. After 3, 6, andhrs, a small aliquot 24 was taken out in order to monitor the reaction progress. After completion, the reaction product was washedwith 20 mL of water three times. Finally, the product was dried in a vacuum oven at 70 . o. C overnight.


decomposition products Specific hazards arising from the chemical Decomposition products may include the following materials: carbon dioxide carbon monoxide nitrogen oxides In a fire or if heated, a pressure increase will occur and the container may burst. Use dry chemical, CO₂, water spray (fog) or foam. Dry sand or other suitable absorbent.
