Yes, hexamine and hexamethylenetetramine are the same substance with the formula C₆H₁₂N₄. The English name “hexamethylenetetramine” may also appear in documents. When purchasing, it is important to check not only the name but also GOST 1381-73, the mass fraction of the main substance, amines, water, ash, residue after ignition and permanganate number. For an enterprise, this helps avoid an ordering mistake and accurately match the batch to the internal specification.
When receiving hexamine, the integrity of the bags, labelling, production date, quality certificate and the batch’s compliance with GOST 1381-73 are checked. Laboratory control focuses on the content of the main substance, the mass fraction of amines, water, ash, residue after ignition and permanganate number. Visually, the product should be a white powder, without wetting, foreign inclusions or dense lumps. If the batch differs in colour, smell or free-flowing quality, it is better to check it before transferring it into production.
Hexamine is sensitive to moisture and warehouse conditions, so it is stored in a dry, ventilated room, in sealed factory packaging. If it gets wet, the powder can cake, become harder to dose and create difficulties when preparing working mixtures. Ventilation also matters because the product is classified as flammable, and dust requires control if handling conditions are violated.
When working with hexamine, personnel use safety goggles, gloves, protective clothing and a respirator if dust is generated. The product is flammable, so there must be no open flame, sparks, overheated equipment or ignition sources nearby. When decanting, it is important to reduce dusting, prevent contamination of the product and keep the work area clean. Spills are collected carefully, without dispersing the powder around the room, and further handling follows the enterprise’s instructions and safety data sheet.
