Physical and Chemical Properties | Cubic alkanes scientific name pentacyclic [4,2,O,O2,5,O3,8,O4,7] octane, rhomboid crystals are obtained by crystallization from methanol and sublimation above room temperature at atmospheric pressure. Melting point 130-131 °c (measured in a capped capillary). Unstable to heat, 200 ℃ can be decomposed. [24] cycloaddition can be carried out from cyclic butadiene with 2, 5-dibromo-p-benzoquinone, the product is then subjected to [22] cycloaddition under the action of light, this is followed by treatment with potassium hydroxide to give a cubic alkane -1, 3-dicarboxylic acid, which is decarboxylated by a free radical method to give a cubic alkane. The main use of cubic alkanes is as a chemical reagent for chemical research work. FIG. 1 is a molecular structure diagram of a cubic alkane. |
