| 20080306306 | Method for Producing 2-Adamantanol and 2-Adamantanone - The present invention is a process for producing 2-adamantanol and 2-adamantanone from 1-adamantanol, by using as a catalyst a substance comprising at least one kind of acid catalyst selected from Lewis acid(s) and solid acid(s) that coexist with at least one kind selected from the group consisting of carboxylic acids, sulfonic acids, and phosphoric acids, and provides a process suitable for mass production of 2-adamantanol and 2-adamantanone selectively with high efficiency without using sulfuric acid as a catalyst, thereby enabling laborsaving in waste acid treatment step and drastic reduction of the reaction time. | 12-11-2008 |
| 20090131729 | METHOD FOR PRODUCTION OF ADAMANTANE - Provided is a method for production of adamantanes, in which, when a tricyclic saturated hydrocarbon compound having 10 or more carbon atoms is isomerized in the presence of a solid catalyst to give adamantanes, no solid matter derived from an oxygen-containing compound is formed or accumulated in the inlet or the bottom of an isomerization reactor by providing a pre-reactor in an isomerization step even if the oxygen-containing compound is present in a raw material to be supplied. | 05-21-2009 |
| 20090177019 | PROCESS FOR PRODUCING ADAMANTANE - Provided is a method for production of adamantane which enables producing a high-purity adamantane at low cost and with high efficiency by using effectively trimethylenenorbornane contained in a heavy raffinate heavy and having conventionally been no use other than fuels and the like, and which enables alleviating poisoning of a catalyst used in isomerization and corrosion of devices, whereby an industrially advantageous adamantane can be produced. In addition, the process for producing adamantane including an isomerization process of isomerizing trimethylenenorbornane contained in a raffinate obtained from a platfinate is characterized by including a water-washing removal process of removing sulfolane in a trimethylenenorbornane concentrate to be supplied in the isomerization process by water-washing. | 07-09-2009 |
| 20100056663 | ADAMANTANE DERIVATIVE, METHOD FOR PRODUCING THE SAME, AND RESIN COMPOSITION CONTAINING ADAMANTANE DERIVATIVE - The present invention is an adamantane derivative which provides optical characteristics such as transparency, (long term) light resistance and the like, long term heat resistance, electric characteristics such as dielectric constant and the like, and good mechanical properties; a production method thereof; and a resin composition containing the above-mentioned adamantane derivative that is an adamantane derivative represented by general formulae (I) to (III); for example, a production method of an adamantane derivative represented by the general formula (III) by reacting an adamantane derivative represented by the general formula (II) with acrylates, a resin composition containing an adamantane derivative represented by the general formula (II) and an epoxy resin curing agent, and a resin composition containing an adamantane derivative represented by the general formula (III) and a thermopolymerization initiator or a photopolymerization initiator. | 03-04-2010 |
| 20110060175 | METHOD FOR MANUFACTURING COMPOUNDS HAVING AN ADAMANTANE STRUCTURE - [Problem to be Solved]The object of the present invention is to provide an industrially favorable production process whereby adamantanes can be produced in a high yield using a catalyst, which is used for the isomerization reaction of a tricyclic saturated hydrocarbon compound having 10 or more carbon atoms, does not require a complicated waste liquid treatment operation, and makes high-yield production of adamantanes possible.
