What is Cyclopentyl methyl ether?
Description
Cyclopentyl methyl ether (CPME) is a useful alternative solvent to THF, 2-MeTHF, dioxane, and other ether solvents due to desirable properties such as a high boiling point, low formation of peroxides, and relative stability under acidic and basic conditions.
Chemical properties
Clear liquid
The Uses of Cyclopentyl methyl ether
Cyclopentyl methyl ether (CPME) is an alternative to ether solvents such as THF, diethyl ether, and MTBE with a higher resistance to peroxide formation. The more environmentally conservative CPME solvent replaces hazardous solvents in order to achieve sustainability and reduce environmental and operational costs. CPME offers considerable potential and advantage as a direct replacement for CH2Cl2 in binary eluents using MeOH as the modifier with MeOH-DMC and i-PrOH-EtOAc.
The Uses of Cyclopentyl methyl ether
Cyclopentyl methyl ether is a hydrophobic ether solvent widely used in Grignard reaction, Friedel-Crafts reaction, Claisen condensation and Beckmann reaction. It plays an important role in extraction and polymerization reactions as well as in surface coatings. It is considered as a replacement for tetrahydrofuran, methyl tert-butyl ether, dioxane and other existing ether solvents due to its excellent properties like high boiling point and relative stability under acidic and basic conditions.
The Uses of Cyclopentyl methyl ether
Greener alternative solvent in reactions containing the following reagents:
- Alkali agents
- Lewis acid-mediated reactions
- Organometallic
- Reduction and Oxidation
- Transition metal catalysts
- Azeotropic water removal
Can also be used in extraction, polymerization, crystallization and surface coatings.
The toxicological assessment of cyclopentyl methyl ether (CPME) as a green solvent.
General Description
Cyclopentyl methyl ether (CPME) is a greener alternative to other ethereal solvents such as tetrahydrofuran (THF), 2-methyl tetrahydrofuran (2-MeTHF), dioxane (carcinogenic), tert-Butyl methyl ether (MTBE), and 1,2-dimethoxyethane (DME) and thus has been enhanced for "Safer Solvents and Auxiliaries".
