| 20100240912 | METHOD FOR PRODUCING CARBONATE COMPOUND - The present invention is to provide a production process capable of selectively producing various kinds of fluorine-containing carbonate compounds without any inhibition in high yields without using phosgene and without producing hydrogen chloride as a by-product. The present invention relates to a process for producing a fluorine-containing compound having a carbonate bond by reacting a compound (1) with a fluorine-containing compound having an OH group. In the formula (1) shown below, X | 09-23-2010 |
| 20100249436 | METHOD FOR PRODUCING CARBONATE COMPOUND - The present invention is to provide a novel production process capable of selectively producing various kinds of carbonate compounds without any inhibition in high yields without using phosgene and without producing hydrogen chloride as a by-product. The present invention relates to a process for producing a compound having a carbonate bond by reacting a compound (1) with a compound having one OH group or a compound having two or more OH groups in the presence of a halogen salt. In the formula (1) shown below, X | 09-30-2010 |
| 20110067733 | METHOD FOR CLEANING WITH FLUORINE COMPOUND - To provide a cleaning method capable of favorably removing an object to be cleaned having a plasma polymer formed in a plasma etching step employing a fluorinated gas. | 03-24-2011 |
| 20110214694 | SUPERCRITICAL PROCESSING APPARATUS AND SUPERCRITICAL PROCESSING METHOD - Disclosed is a supercritical processing apparatus and a supercritical processing method for suppressing the pattern collapse or the injection of material constituting a processing liquid into a substrate. A processing chamber receives a substrate subjected to a processing with supercritical fluid, and a liquid supply unit supplies a processing liquid including a fluorine compound to the processing chamber. A liquid discharge unit discharges the supercritical fluid from the processing chamber, a pyrolysis ingredient removing unit removes an ingredient facilitating the pyrolysis of a liquid from the processing chamber or from the liquid supplied from the liquid supply unit, and a to heating unit heats the processing liquid including a fluorine compound of hydrofluoro ether or hydrofluoro carbon. | 09-08-2011 |
