    en.wikipedia.org/wiki/1,3,5-Trioxane

    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 ...

    en.wikipedia.org/wiki/1,3,5-Trithiane

    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.

  5. Trioxane - Wikipedia

    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]

  6. Trimer (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Trimer_(chemistry)

    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]

  7. Thioformaldehyde - Wikipedia

    en.wikipedia.org/wiki/Thioformaldehyde

    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.

  8. Paraldehyde - Wikipedia

    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 ...
