Abstract
Official abstract text for this publication.
Provided is a novel compound that is expected to be used as a solvent, a cleaning agent, a blowing agent, an intermediate for a functional material, and so forth, as well as a production method therefor and uses thereofAs the novel compound, 1,2-dichoro-1-(2,2,2-trifluoroethoxy)ethylene is provided. This compound can be produced, for example, by allowing an addition reaction between 2,2,2-trifluoroethanol and trichloroethylene in the presence of a base.
First claim
Opening claim text (preview).
The invention claimed is: 1. 1,2-Dichloro-1-(2,2,2-trifluoroethoxy)ethylene represented by the following formula (1) 2. 1,2-Dichloro-1-(2,2,2-trifluoroethoxy)ethylene according to claim 1 selected from the group consisting of trans-1,2-dichloro-1-(2,2,2-trifluoroethoxy)ethylene, cis-1,2-dichloro-1-(2,2,2-trifluoroethoxy)ethylene, and a combination thereof. 3. A production method for 1,2-dichloro-1-(2,2,2-trifluoroethoxy)ethylene according to claim 1 comprising allowing an addition reaction between 2,2,2-trifluoroethanol and trichloroethylene in the presence of a base. 4. The production method according to claim 3 , wherein the addition reaction is carried out in the presence of an alkali metal hydroxide. 5. The production method according to claim 3 , wherein the addition reaction is carried out in the presence of sodium hydroxide and/or potassium hydroxide. 6. A solvent, cleaning agent or blowing agent, comprising a composition containing 1,2-dichloro-1-(2,2,2-trifluoroethoxy)ethylene according to claim 1 . 7. A cleaning agent for removing a flux or a process oil, comprising a composition containing 1,2-dichloro-1-(2,2,2-trifluoroethoxy)ethylene according to claim 1 . 8. A method of removing a contaminant from a substrate, comprising bringing the substrate into contact with a composition containing 1,2-dichloro-1-(2,2,2-trifluoroethoxy)ethylene according to claim 1 . 9. The method according to claim 8 , wherein the contaminant is a flux or a process oil.
