Cyclopentyl methyl ether

Cyclopentyl methyl ether (CPME), also known as methoxycyclopentane, is new environmentally friendly hydrophobic ether solvent with high performance, and could replace tetrahydrofuran, methyl tetrahydrofuran, methyl tert-butyl ether and dioxane and other ether solvents. As a reaction solvent, it can be used for reaction such as Grignard reaction, coupling reaction, coupling amination reaction, metal reduction reaction, Lewis acid reaction and Fried-Clark reaction, etc. It is also used for extraction, crystallization, surface treatment and polymerization processes.

Clear liquid

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.

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.

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.

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".

Highly flammable

Cyclopentyl methyl ether can be obtained by etherification reaction of refined cyclopentene mixed with methanol and heated and gasified through a fixed bed of strongly acidic cation exchange resin.
