| 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. |
cubane - Introduction
cubane (chemical formula: C8H18) is a colorless, odorless liquid alkane compound with low density at room temperature. The following is a description of the nature, use, preparation and safety information of cubane:
Nature:
1. cubane is a linear hydrocarbon alkane with 8 carbon atoms and has the molecular formula C8H18. It is a saturated hydrocarbon with only carbon-carbon single bonds and carbon-hydrogen single bonds in the molecule.
2. cubane has a low boiling point and flash point, and is volatile.
3. It is a flammable substance mixed with air and can be burned to produce carbon dioxide and water.
4. Because cubane is easily affected by oxygen in the air during preparation and transmission, it is often added with stabilizers to increase its stability.
Use:
1. cubane is mainly used as a solvent and is widely used in chemical experiments, pharmaceuticals, inks, coatings, detergents and other industrial fields.
2. It is also used as a fuel additive to improve the combustion performance of gasoline and improve engine performance.
3. cubane can also be used as a calibration gas for the calibration of instruments such as gas chromatographs.
Preparation Method:
cubane can be prepared by the catalytic hydrogenation reaction of anhydrous elemental acids of hydrocarbons. The common method is to hydrogenate butane (C4H10) to obtain N-octane (C8H18), and then obtain pure cubane by cracking or refining methods.
Safety Information:
1. cubane is flammable and should be kept away from open flames, heat sources and sparks.
2. Avoid using cubane near potential ignition sources.
3. When using cubane, keep good ventilation and avoid inhaling its vapor.
4. If there is an accidental leak, immediate measures should be taken to prevent spread and prevent it from entering the sewer or groundwater system.
5. When using cubane, should wear appropriate protective gloves and eye protection equipment.
