The dominant use of hexamethylenetetramine is in the production of solid (powder) or liquid phenolic resins and phenolic resin moulding compounds, in which it is added as a hardening component. These products are used as binders, e.g., in brake and clutch linings, abrasives, non-woven textiles, formed parts produced by moulding processes, and ...

Hexamethylenetetramine (HMTA or hexa) is by far the most important curing agent for novolac. Typically, about 10% of hexa will be added to novolac. The hydrolysis of hexa by the water in novolac affords, via aminoalcohols (Figure 28), methylene …

2024年6月14日 · Hexamethylenetetramine, as methenamine hippurate or methenamine mandelate, is used for treating urinary tract infections. In acidic environments, it is believed to exert its antimicrobial effects by converting to formaldehyde.

HMTA is used in the rubber industry to prevent vulcanized rubber from blocking and as a accelerator, as a curing agent for thermosetting resins (particularly phenyl-formaldehyde and urea-formaldehyde resins; in foundry mold castings as part of binder resins, in the production of nitrilotriacetic acid; in the manufacture of adhesives and ...

2013年4月18日 · Hexamine is a synthetically versatile reagent used in organic synthesis during the last years. In particular, in the Duff and Sommelet reactions hexamethylenetetramine acts as the formyl carbon source, while in the Delepine reaction it provides the primary amino groups.

5 小时之前 · HMTA, an essential chemical compound in the oil and gas industry, is widely used to inject in-situ or preformed particle gel into oil reservoirs 1,2,3,4.This material can act as a surface-active ...

2025年1月27日 · Hexamethylenetetramine is mainly used as the curing agent of plastic and resin, the catalyst and foaming agent of aminoplast, rubber vulcanization accelerator (accelerator H), and the shrink-proof agents of textiles.

The available literature on hexamethylenetetramine (hexamine) was reviewed with emphasis on its toxicology and epidemiology, its thermal decomposition and regulatory concerns related to its uses. Large quantities of hexamine are used in the foundry, tire and rubber, and phenolformaldehyde resins ind …

Structural characterization of the decomposition product of hexamethylenetetramine (HMTA). A combined theoretical and spectroscopic study

Hexamethylenetetramine (HMTA) may be used as: Raw material in the synthesis of blue emitting boron carbon oxynitride (BCNO) phosphors and Zinc oxide (ZnO) nanorods. Catalyst in the synthesis of 2-amino-4H-pyran derivatives. Surfactant in the synthesis of HMTA capped transition metals doped ZnS nanoparticles.
