CAS 80-15-9 corresponds to Cumene hydroperoxide, a significant organic peroxide widely utilized in various industrial applications. As a reliable supplier of CAS 80-15-9, I am delighted to delve into the details of this chemical, including its molecular weight, properties, applications, and safety considerations.
Molecular Weight of Cumene Hydroperoxide (CAS 80-15-9)
The molecular formula of Cumene hydroperoxide is C₉H₁₂O₂. To calculate its molecular weight, we need to consider the atomic weights of each element present in the molecule. The atomic weight of carbon (C) is approximately 12.01 g/mol, hydrogen (H) is about 1.008 g/mol, and oxygen (O) is around 16.00 g/mol.
In Cumene hydroperoxide, there are 9 carbon atoms, 12 hydrogen atoms, and 2 oxygen atoms. The calculation of the molecular weight is as follows:
- For carbon: 9 atoms × 12.01 g/mol = 108.09 g/mol
- For hydrogen: 12 atoms × 1.008 g/mol = 12.096 g/mol
- For oxygen: 2 atoms × 16.00 g/mol = 32.00 g/mol
Adding these values together, the molecular weight of Cumene hydroperoxide is 108.09 + 12.096 + 32.00 = 152.186 g/mol.
Properties of Cumene Hydroperoxide
Cumene hydroperoxide is a colorless to pale yellow liquid with a characteristic odor. It is sparingly soluble in water but soluble in many organic solvents such as benzene, toluene, and acetone. This chemical is a powerful oxidizing agent and is sensitive to heat, shock, and friction. It has a relatively low flash point, which means it can easily ignite when exposed to an open flame or a spark.
Applications of Cumene Hydroperoxide
Cumene hydroperoxide has a wide range of applications in various industries:


Chemical Synthesis
It is a key intermediate in the production of phenol and acetone through the Hock process. In this process, Cumene is first oxidized to Cumene hydroperoxide, which is then cleaved to form phenol and acetone. These two chemicals are essential building blocks in the production of plastics, resins, and synthetic fibers.
Polymerization
Cumene hydroperoxide is used as an initiator in the polymerization of various monomers such as styrene, acrylonitrile, and butadiene. It helps to start the polymerization reaction by generating free radicals, which react with the monomers to form polymer chains.
Bleaching Agent
In the pulp and paper industry, Cumene hydroperoxide is used as a bleaching agent to remove color from wood pulp. It is an effective alternative to chlorine-based bleaching agents, which can produce harmful by-products.
Safety Considerations
As an oxidizing agent, Cumene hydroperoxide poses certain safety risks. It can cause severe skin and eye irritation, and inhalation of its vapors can be harmful to the respiratory system. In addition, it is highly reactive and can react violently with reducing agents, combustible materials, and other incompatible substances.
When handling Cumene hydroperoxide, it is essential to follow proper safety procedures. This includes wearing appropriate personal protective equipment such as gloves, goggles, and a respirator, and storing the chemical in a cool, dry, and well-ventilated area away from sources of heat, ignition, and incompatible materials.
