Alcohols from Carbonyl Compounds: Reduction02:23

Alcohols from Carbonyl Compounds: Reduction

12.9K
Reduction is a simple strategy to convert a carbonyl group to a hydroxyl group. The three major pathways to reduce carbonyls to alcohols are catalytic hydrogenation, hydride reduction, and borane reduction.
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis

13.2K
Overview
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Preparation of Alcohols via Addition Reactions

8.0K
Overview
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...

Area of Science:

  • Biomass Valorization
  • Green Chemistry
  • Polymer Science

Background:

  • Lignocellulosic biomass is an abundant renewable resource.
  • Efficient lignin isolation is crucial for biomass valorization.
  • Deep eutectic solvents (DES) offer tunable properties for biomass processing.

Purpose of the Study:

  • To explore ternary deep eutectic solvent systems for efficient lignocellulosic biomass fractionation.

  • Reactive fractionation of birchwood using choline chloride, oxalic acid, and ethylene glycol (DES).
  • Optimization of reaction temperature, time, and DES composition.
  • Characterization of lignin structure using 2D HSQC NMR and GPC.
  • Synthesis of lignin nanoparticles (LNPs) via hydrotropic and pH-induced flash precipitation.

Main Results:

  • High lignin yield (66%) with significant retention of β-O-4 aryl ether linkages.
  • Ethylene glycol incorporation is temperature- and time-dependent, with optimal preservation at 140-160 °C.
  • Higher EG content mitigated structural degradation; increasing temperature promoted aryl ether cleavage.
  • Tunable, stable LNPs with favorable surface charge were synthesized from EG-decorated lignins.

Conclusions:

  • Deep eutectic solvents enable efficient lignin isolation with tunable structural features.
  • Controlled lignin modification with EG influences structural integrity and downstream applications.
  • EG-decorated lignins are promising precursors for synthesizing functional lignin nanoparticles for material applications.
