摘要:
The present invention relates to a process for the preparation of monohydroperfluoroalkanes, bis(perfluoroalkyl)phosphinates and perfluoroalkylphosphonates which comprises at least the treatment of at least one perfluoroalkylphosphorane with at least one base in a suitable reaction medium.
摘要:
The present invention relates to a process for the preparation of bis(perfluoroalkyl)phosphinic acids comprising at least the reaction of at least one difluorotris(perfluoroalkyl)phosphorane or at least one trifluorobis(perfluoroalkyl)phosphorane with hydrogen fluoride in a suitable reaction medium, and heating of the resultant reaction mixture. The invention also relates to salts of bis(perfluoroalkyl)phosphinic acids and to the use thereof.

摘要:
The present invention relates to an interactive security element comprising at least one volume hologram the latter being responsive to at least one applied external stimulus and exhibits a defined optical effect in form of an image, whereby the optical effect in form of an image is preferably different when being observed at different angles of view and the different images may be observed at least after an external stimulus has been applied, to a method of verifying said interactive security element as well as to the use thereof for verification, identification, authentication or anti-counterfeiting purposes, in particular as a public feature to security products such as banknotes, passports, identification documents, tickets, credit cards, smart cards, etc., and for brand and production protection.
