What is the chemical structure of TBHP with CAS 75 - 91 - 2?
TBHP, or tert - butyl hydroperoxide, identified by the CAS number 75 - 91 - 2, is a well - known and highly useful organic peroxide. As a reliable supplier of TBHP with CAS 75 - 91 - 2, I am here to delve into the chemical structure of this important compound and its associated properties and applications.
Chemical Structure of TBHP
The chemical formula of TBHP is C₄H₁₀O₂. Its structure is characterized by a tert - butyl group (C(CH₃)₃) and a hydroperoxide group (-OOH). The tert - butyl group is a bulky, branched alkyl group, which consists of a central carbon atom bonded to three methyl groups ( - CH₃) and another single - bond attached to the oxygen atom of the hydroperoxide group.
In a more detailed view, the central carbon of the tert - butyl moiety has a tetrahedral geometry, with each of the three methyl groups placed at the vertices of the tetrahedron, and the bond between the central carbon and the oxygen of the hydroperoxide group completing the four - coordinate structure. The hydroperoxide group contains an oxygen - oxygen single bond (O - O), which is relatively weak compared to carbon - carbon or carbon - hydrogen bonds. This weak O - O bond is the key to the high reactivity of TBHP. The oxygen atom of the hydroperoxide group that is not part of the O - O bond is further bonded to a hydrogen atom.
The structural features of TBHP have a significant impact on its physical and chemical properties. The presence of the bulky tert - butyl group provides a certain degree of steric hindrance, which affects its reaction rates and selectivity in chemical reactions. The hydroperoxide group, on the other hand, endows TBHP with its oxidizing properties and makes it a useful reagent in various chemical processes.
Properties and Applications
Physical Properties
TBHP is a clear, colorless liquid at room temperature. It has a boiling point of approximately 89 - 90 °C at 100 mmHg. Its density is around 0.9 g/cm³. TBHP is soluble in many organic solvents such as alcohols, ethers, and hydrocarbons, but has limited solubility in water.
Chemical Properties
Due to the presence of the weak O - O bond in the hydroperoxide group, TBHP is a strong oxidizing agent. It can abstract hydrogen atoms from suitable substrates, leading to the formation of radicals. These radicals can then initiate a variety of chemical reactions, including polymerization, oxidation, and epoxidation.
Applications
One of the most common applications of TBHP is in the field of polymerization. It can act as an initiator in the polymerization of various monomers, such as styrene and acrylates. In these reactions, the radicals generated from TBHP react with the monomers, starting the chain - growth process to form polymers with specific molecular weights and structures.
TBHP is also widely used in oxidation reactions. It can oxidize a variety of organic compounds, such as alcohols to aldehydes or ketones, and alkenes to epoxides. In the synthesis of fine chemicals and pharmaceuticals, TBHP - mediated oxidation reactions are often employed to introduce specific functional groups into the target molecules.
Comparison with Other Organic Peroxides
When discussing TBHP, it is also interesting to compare it with other related organic peroxides. For example, DTBP | CAS 110 - 05 - 4 | Di - tert - butyl Peroxide and Di - Tert - Butyl Peroxide. DTBP has a different chemical structure compared to TBHP. DTBP contains two tert - butyl groups connected by a peroxide bond (O - O). The two bulky tert - butyl groups in DTBP provide more steric hindrance than the single tert - butyl group in TBHP. This difference in structure leads to differences in their reactivity and applications. DTBP is often used in high - temperature polymerization reactions due to its relatively high thermal stability.
Another related organic peroxide is DCLBP | CAS 133 - 14 - 2 | Di(2,4 - chlorobenzoyl) Peroxide. DCLBP has a more complex structure with two 2,4 - chlorobenzoyl groups connected by a peroxide bond. It is mainly used in the polymerization of vinyl chloride and other vinyl monomers. The presence of the chlorine atoms in the benzoyl groups affects its reactivity and solubility properties.
Safety Considerations
As an organic peroxide, TBHP is a hazardous substance. It is flammable and can react violently with reducing agents, strong acids, and organic materials. It can also cause severe skin and eye irritation. Therefore, proper safety precautions must be taken when handling TBHP. This includes wearing appropriate personal protective equipment, such as gloves, goggles, and lab coats, and storing the compound in a cool, dry place away from heat sources and incompatible materials.
