Trimers (chemistry)

thumb|Marking of product made of Melamine Melamine is an organic compound with the formula C3H6N6. This white solid is a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 66% nitrogen by mass, and its derivatives have fire-retardant properties due to its release of nitrogen gas when burned or charred. Melamine can be combined with formaldehyde and other agents to produce melamine resins. Such resins are characteristically durable thermosetting plastic used in high-pressure decorative laminates such as Formica, melamine dinnerware including cooking utensils, plat

Paraldehyde is the cyclic trimer of acetaldehyde molecules. Formally, it is a derivative of 1,3,5-trioxane, with a methyl group substituted for a hydrogen atom at each carbon. The corresponding tetramer is metaldehyde. A colourless liquid, it is sparingly soluble in water and highly soluble in ethanol. Paraldehyde slowly oxidizes in air, turning brown and producing an odour of acetic acid. It attacks most plastics and rubbers and should be kept in glass bottles.

chemical compound belonging to the class of triazine

chemical term for a product derived from three monomers

1,3,5-Trioxane, sometimes also called trioxane, is a chemical compound with molecular formula CHO. It is a white, highly water-soluble solid with a chloroform-like odor. It is a stable cyclic trimer of formaldehyde, and one of the three trioxane isomers; its molecular backbone consists of a six-membered ring with three carbon atoms alternating with three oxygen atoms.

chemical compound

1,3,5-Triazine, also called '''s-triazine', is an organic chemical compound with the formula (HCN). It is a six-membered heterocyclic aromatic ring, one of several isomeric triazines. s''-Triazine —the "symmetric" isomer—and its derivatives are useful in a variety of applications.

chemical compound

weakly bounded molecule consisting of three helium atoms

Tripropylene, also known as propylene trimer, is usually sold as a mixture of structural isomers of nonene. This mixture is obtained by oligomerization of propene: 3 C3H6 → C9H18 In this process, two double bonds are lost and one is retained as illustrated by the isomer shown in the figure. The reaction is catalyzed by acids, such as polyphosphoric acid. A variety of catalysts have been explored. The reaction proceeds via the formation of a carbocation ((CH3)2CH+), which attacks another propylene unit, generating a new carbocation, etc. This kind of process affords mixtures (C3H6)n.
