20120330072 | METHOD FOR PRODUCING SUBSTITUTED FLUORINE-CONTAINING OLEFIN - This invention relates to a method of reacting fluoroolefin with an organic magnesium compound in the presence of a catalyst comprising nickel or palladium so as to efficiently produce fluoroolefin, such as TFE, in which a fluorine (F) atom or atoms bonded to the sp | 12-27-2012 |
20130324757 | PREPARATION METHOD FOR FLUORINE-CONTAINING OLEFINS HAVING ORGANIC-GROUP SUBSTITUENTS - An object of the present invention is to provide a method that enables the easy and efficient (high yield, high selectivity, low cost) preparation of a fluorine-containing olefin substituted with an organic group or groups from a fluorine-containing olefin. | 12-05-2013 |
20140234198 | ETCHING METHOD AND METHOD FOR PERFORMING SURFACE PROCESSING ON SOLID MATERIAL FOR SOLAR CELL - Provided is an etching method including: (1) bringing a material containing at least one organic compound having an N—F bond into contact with the surface of a solid material; and (2) a step of heating the solid material; whereby etching can be performed safely and in a simple manner, at a higher etching rate, without the use of a high-environmental-load gas that causes global warming or highly reactive and toxic fluorine gas or hydrofluoric acid. The etching method may further include: (3) a step of exposing the solid material to light from the side of the material containing at least one organic compound having an N—F bond; and (4) a step of removing the material containing at least one organic compound having an N—F bond together with the residue remained between said material and the solid material. In particular, performing heating at a high temperature and applying light irradiation make it possible to form inverted pyramid-shaped recesses that are suitable for applying light-trapping and/or anti-reflection processing to the surface of the solid material for a solar cell. | 08-21-2014 |
