1,3,5-Trioxane, sometimes also called trioxane or trioxin, is a chemical compound with molecular formula C 3 H 6 O 3. 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 ...
Trithiane is the dithioacetal of formaldehyde. Other dithioacetals undergo similar reactions to the above. It is also a precursor to other organosulfur reagents. For example, chlorination in the presence of water affords the chloromethyl sulfonyl chloride: [4] (CH 2 S) 3 + 9 Cl 2 + 6 H 2 O → 3 ClCH 2 SO 2 Cl + 12 HCl Sample of sym-trithiane.
Molecular formaldehyde. A colorless gas with a characteristic pungent, irritating odor. It is stable at about 150 °C, but it polymerizes when condensed to a liquid. 1,3,5-Trioxane, with the formula (CH 2 O) 3. It is a white solid that dissolves without degradation in organic solvents. It is a trimer of molecular formaldehyde.
The three isomers are: 1,2,3-trioxane, a hypothetical compound that is the parent structure of the molozonides [1]; 1,2,4-trioxane, a hypothetical compound whose skeleton occurs as a structural component of some antimalarial agents (artemisinin and similar drugs) [2]
Cyclotrimerization of formaldehyde affords 1,3,5-Trioxane: 1,3,5-Trithiane is the cyclic trimer of the otherwise unstable species thioformaldehyde. This heterocycle consists of a six-membered ring with alternating methylene bridges and thioether groups. It is prepared by treatment of formaldehyde with hydrogen sulfide. [6]
Thioformaldehyde is the organosulfur compound with the formula CH 2 S. It is the simplest thioaldehyde.This compound is not observed in the condensed state (solid or liquid) because it oligomerizes to 1,3,5-trithiane, which is a stable colorless compound with the same empirical formula.
The product of the reaction is dependent on the temperature. At room temperature and higher, the formation of trimer is preferred, but at lower temperatures, around −10 °C, the tetramer metaldehyde is more likely to be produced. [7] The reaction of sulfuric acid and acetaldehyde is exothermic, with the heat of reaction being −113 kJ·mol ...
N- and C-substituted triazines are used industrially.The most common derivative of 1,3,5-triazine is 1,3,5-triazine-2,4,6-triamine, commonly known as melamine or cyanuramide.
