General Description

Carbonic acid, methyl 2,2,2-trifluoroethyl ester is a chemical compound with the formula CH3OC(O)CH2CF3. It is derived from carbonic acid and is commonly used as a solvent, intermediate, and in the production of pharmaceuticals and agrochemicals. Carbonic acid, methyl 2,2,2-trifluoroethyl ester is a colorless liquid with a sweet, fruity odor, and is highly flammable. It is also known to have low toxicity, but may cause irritation to the skin and eyes upon contact. The compound is not considered to be persistent in the environment and is expected to degrade rapidly. However, it is important to handle and store this chemical with care to prevent any potential hazards or environmental impact.

Correlation of the rates of solvolysis of methyl chloroformate with solvent properties

The specific rates of solvolyis of methyl chloroformate are very well correlated by the extended Grunwald-Winstein equation over a wide range of solvents; the pathway is believed to be predominantly addition-elimination, except that a positive deviation for solvolysis in 90% 1,1,1,3,3,3- hexafluoropropan-2-ol suggests an 80% contribution from an ionisation mechanism.

Continuous method for preparing carbonate esters

In one embodiment, a continuous process for preparing organic carbonate solvent of Formula (I) as described herein comprises contacting a first reactant (an alcohol) with a reactive carbonyl source (carbonyldiimidazole (CDI) or an alkylchloroformate) in the presence of a catalyst in reaction stream flowing through a continuous flow reactor at temperature 20° C. to about 160° C. and at a flow rate providing a residence time in the range of about 0.1 minute to about 24 hours; collecting a reactor effluent exiting from the continuous flow reactor; recovering a crude product from the reactor effluent; and distilling the crude product to obtain the organic carbonate compound of Formula (I). In another embodiment, the first reactant is an epoxide and the carbonyl source is carbon dioxide.
