It involves the study of hydrocarbons, alcohols, acids, esters, and many other types of compounds.
Organic chemistry has many practical applications, including the development of new drugs, materials, and fuels.
It also plays a crucial role in unders...
Distillation is a process of separating components of a mixture based on their boiling points.
It involves heating the mixture to vaporize the component with the lowest boiling point
The vapor is then condensed and collected as a separate liquid
This process can be used to purify liquids, separate different components of a mixture, and extract essential oils from plants
Examples include the distillation of crude oil to pro...
Distillate is the purified liquid obtained through distillation, while residue is the remaining substance after distillation.
Distillate is the product obtained by heating a liquid mixture and collecting the condensed vapor.
It is the purified liquid that has a higher boiling point than the other components of the mixture.
Residue is the substance left behind after the distillation process.
It consists of the components th...
Pump is used to move liquids while compressor is used to compress gases.
Pump moves liquids while compressor compresses gases
Pump has lower pressure while compressor has higher pressure
Examples of pumps include water pumps, fuel pumps, and vacuum pumps while examples of compressors include air compressors and refrigeration compressors
A pump is a mechanical device used to move fluids from one place to another.
Pumps can be classified into two types: positive displacement pumps and centrifugal pumps.
Positive displacement pumps move fluid by trapping a fixed amount and forcing it into a discharge pipe.
Centrifugal pumps use a rotating impeller to create a flow of fluid.
Pumps are used in various industries such as water treatment, oil and gas, and chemic...
pH difference between acidic and basic is the concentration of hydrogen ions in the solution.
Acidic solutions have a pH less than 7, while basic solutions have a pH greater than 7.
The pH scale ranges from 0 to 14, with 7 being neutral.
Each unit on the pH scale represents a tenfold difference in the concentration of hydrogen ions.
For example, a solution with a pH of 3 is ten times more acidic than a solution with a pH o...
Hydrogenation reaction is a chemical reaction in which hydrogen is added to a molecule, typically an unsaturated organic compound.
Hydrogenation is used in the food industry to convert liquid oils into solid fats.
It is also used in the production of margarine and shortening.
Hydrogenation can be catalyzed by metals such as nickel, palladium, or platinum.
The reaction can be carried out under high pressure and high tempera...

There are various types of reactors used in production processes, such as batch reactors, continuous stirred-tank reactors, and plug flow reactors.
Batch reactors are used for small-scale production and allow for easy control of reaction conditions.
Continuous stirred-tank reactors are used for continuous production and have good mixing capabilities.
Plug flow reactors are used for reactions that require a specific reside...
Types of distillation columns include batch, continuous, fractional, and steam distillation.
Batch distillation: Used for small-scale production and involves separating components based on boiling points.
Continuous distillation: Used for large-scale production and involves a continuous feed of mixture and product removal.
Fractional distillation: Used to separate components with closer boiling points by creating multiple...

Kaizen and 5s are continuous improvement methodologies used in production to enhance efficiency and quality.
Kaizen is a Japanese term meaning 'continuous improvement' and focuses on making small, incremental changes to processes to improve efficiency and quality.
5s is a methodology focused on organizing the workplace to improve efficiency and eliminate waste. The 5s stand for Sort, Set in order, Shine, Standardize, and...
The Grignard reaction is a commonly used naming reaction in organic chemistry.
Involves the reaction of an organomagnesium halide with a carbonyl compound to form a new carbon-carbon bond
Named after French chemist Victor Grignard
Commonly used in the synthesis of alcohols, carboxylic acids, and ketones

Vacuum in a column can be created by using a vacuum pump to remove air and other gases from the column.
Use a vacuum pump to remove air and other gases from the column
Ensure all connections are airtight to maintain the vacuum
Monitor the vacuum level regularly to ensure it is maintained
Adjust the vacuum pump settings as needed to achieve the desired vacuum level
Steam ejectors work by using high-pressure steam to create a vacuum for removing gases or vapors from a system.
Steam is expanded through a nozzle to increase its velocity
The high-velocity steam entrains the gases or vapors to be removed
The mixture of steam and gases is then condensed and separated in a diffuser
The condensed steam is usually discharged to a condenser or a drain

Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.
Centrifugal pumps: use a rotating impeller to increase the pressure of a fluid.
Positive displacement pumps: move fluid by trapping a fixed amount and forcing it through the discharge.
Axial flow pumps: move fluid parallel to the impeller shaft.
Examples: Centrifugal pump - water pump, Positive displacement pump - diaphragm pump, A
Unit operations for mass transfer involve processes like distillation, absorption, extraction, and adsorption.
Distillation: Separation of components based on boiling points.
Absorption: Transfer of a solute from gas phase to liquid phase.
Extraction: Transfer of a solute from one liquid phase to another.
Adsorption: Adhesion of molecules to a surface.
