| Application: | CPME is a greener alternative solvent and may be used is a broad range of applications such as:
Extraction of compounds Polymer synthesis Crystallization Surface coatings |
| Features and Benefits: | • Synthetic-based sustainable and safer alternative • Reduces the number of steps required for production • Reduces the amount of water that is required for washing • Eliminates the need for co-solvents for product recovery It has many properties which make it a safer and greener alternative: • Low peroxide formation • High boiling point • Clean organic-water phase separation • Reduced energy to recover |
| General description: | We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Cyclopentyl methyl ether (CPME) is a greener alternative solvent to many aprotic ether 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".
