Carbolic Acid – Properties, Synthesis, Uses and FAQs

What is Carbolic Acid?

Carbolic acid, also known as phenol, is a chemical compound with the molecular formula C6H5OH. It is a white crystalline solid that has a distinct, sweet, and medicinal odor. Carbolic acid was first isolated from coal tar in the 19th century and has since found various applications in different fields.

Chemical Properties of Carbolic Acid are as follows.

1. It is a colorless liquid that has a slightly pungent odor.

2. It is soluble in water and is a polar molecule.

3. It is a weak acid that dissociates in water to form phenol and a proton.

4. It is a good disinfectant and is used to kill bacteria.

5. It is also used as a pesticide and a preservative.

Synthesis of Carbolic Acid

• The synthesis of carbolic acid is a two-step process. In the first step, phenol is reacted with formaldehyde to produce para-hydroxybenzaldehyde. In the second step, this aldehyde is then reduced to carbolic acid.
• The first step in the synthesis of carbolic acid is the reaction of phenol with formaldehyde to produce para-hydroxybenzaldehyde. The reaction is shown below.
• The second step in the synthesis of carbolic acid is the reduction of para-hydroxybenzaldehyde to carbolic acid. The reaction is shown below.

1. Hock Process

The hock process is a bony projection on the posterior surface of the tibia, or shinbone. The hock process is part of the ankle joint, and it helps to stabilize the joint.

The hock process is also called the calcaneal process, the calcaneus, or the heel bone.

2. Oxidation of Benzene to Toluene

Benzene is oxidized to toluene by chromium trioxide in the presence of sulfuric acid.

The overall reaction is:

3C 6 H 6 + CrO 3 + H 2 SO 4 → 3C 7 H 8 + Cr 2 (SO 4 ) 3 + H 2 O

3. Dow Chemical Produced a Copper

-Based Insecticide

In 1944, Dow Chemical Company developed a copper-based insecticide called DBCP. The product was used to control pests in crops and livestock. However, in the late 1970s and early 1980s, it was discovered that DBCP caused severe health problems in workers who were exposed to it, including sterility and cancer. As a result, Dow Chemical withdrew the product from the market in 1979.

4. Hydrolysis of Benzenesulfonate

The hydrolysis of benzenesulfonate is a process that breaks down this molecule into simpler molecules. In general, hydrolysis is the process of breaking down a molecule into smaller pieces by adding water. In this case, the benzenesulfonate molecule is broken down into benzoic acid and sulfate ions.

The hydrolysis of benzenesulfonate can be represented by the following equation:

C 6 H 5 SO 3 Na + H 2 O → C 6 H 5 COOH + Na 2 SO 4

5. Hydrolysis of Chlorobenzene

Chlorobenzene is a colorless, sweet-smelling liquid with the chemical formula C6H5Cl. It is used as an industrial solvent and as a precursor to other chemicals.

Chlorobenzene can be hydrolyzed to form benzene and chloride ions. The hydrolysis reaction is shown below.

C6H5Cl + H2O → C6H6 + HCl

6. Coal Pyrolysis

• Pyrolysis is a thermal decomposition of organic material at elevated temperatures in the absence of oxygen. Coal pyrolysis is the thermal decomposition of coal. The product of coal pyrolysis is a solid, liquid, or gas.
• Solid products include char, tars, and oils. The char is a black, sooty material that is produced by the complete combustion of the coal. The tars are a group of liquid hydrocarbons that are produced by the partial combustion of the coal. The oils are a group of liquid hydrocarbons that are produced by the complete combustion of the coal.
• Liquid products include naphtha, kerosene, diesel fuel, and heavy fuel oil. The naphtha is a light hydrocarbon that is produced by the partial combustion of the coal. The kerosene is a heavy hydrocarbon that is produced by the partial combustion of the coal. The diesel fuel is a heavy hydrocarbon that is produced by the complete combustion of the coal. The heavy fuel oil is a heavy hydrocarbon that is produced by the complete combustion of the coal.
• Gas products include carbon monoxide, hydrogen, methane, and ethane. The carbon monoxide is a poisonous gas that is produced by the partial combustion of the coal. The hydrogen is a combustible gas that is produced by the complete combustion of the coal. The methane is a combustible gas that is produced by the partial combustion of the
