Reactions of Ethers
Ethers (R-O-R’) are compounds formed by replacing hydrogen atoms of an alcohol (R-OH compound) or a phenol (C6H5OH) by an aryl/ acyl group (functional group after removing single hydrogen from an aromatic ring). In this section, reaction, preparation and behavior of ethers are discussed in the context of organic chemistry.
Epoxides
Epoxides are a special class of cyclic ethers which are an important functional group in organic chemistry and generate reactive centers due to their unusual high reactivity. Due to their high reactivity, epoxides are considered to be toxic and mutagenic.
Williamson Ether Synthesis
An organic reaction in which an organohalide and a deprotonated alcohol forms ether is known as Williamson ether synthesis. Alexander Williamson developed the Williamson ether synthesis in 1850. The formation of ether in this synthesis is an SN2 reaction.
DESCRIPTION
TASK
As a process engineer in a chemical manufacturing company, your team has been assigned to prepare the proposal on the process and suitable design of a reactor for catalytic hydrogenation of liquid aldehyde OR ketone into the desired alcohol based on the current industrial demand. The proposal should consist of the following items:
- Process background
1. The chosen materials (liquid aldehydes or ketones) and the desired product.
2. Discuss the available reduction reaction of aldehydes/ketones to alcohol and compare in terms of reaction conditions, types of reactions (phase of reaction andthermodynamic properties) and any relevant information.
3. Justify the advantages of catalytic hydrogenation as compared to other reduction methods.
4. Selection and justification of metal catalyst for the catalytic hydrogenation reaction.
5. Production capacity, conversion, yield and selectivity
