Abstract: The present invention relates to a process for the preparation of β- or γ-unsaturated or saturated carboxylic acids.It relates more particularly to the hydroxycarbonylation of an organic compound comprising a conjugated unsaturation, such as butadiene, by the action of carbon monoxide and water in the presence of a palladium-based catalyst. The carboxylic acids thus obtained are preferably pentenoic acids. According to the invention, the reaction medium after the end of the hydroxycarbonylation stage is treated with hydrogen to reduce the palladium present in the 2+ oxidation state to palladium in the zero oxidation state and the precipitated palladium is recovered.

Abstract: The present invention concerns a process for the preparation of 3-carboxy-4-hydroxybenzaldehydes and derivatives thereof from phenolic compounds carrying formyl and/or hydroxymethyl groups in the 2 and 4 positions. The invention also concerns the preparation of 4-hydroxybenzaldehydes from 3-carboxy-4-hydroxybenzaldehydes. More particularly, the invention concerns the preparation of 3-methoxy-4-hydroxybenzaldehyde and 3-ethoxy-4-hydroxybenzaldehyde, respectively known as "vanillin" and "ethylvanillin". The process for the preparation of 3-carboxy-4-hydroxybenzaldehyde is characterized in that the group in the 2 position in a phenolic compound carrying formyl and/or hydroxymethyl groups in the 2 and 4 positions is selectively oxidized to a carboxy group, and optionally a hydroxymethyl group in the 4 position is selectively oxidized to a formyl group. A successive decarboxylation step for a 3-carboxy-4-hydroxybenzaldehyde produces a 4-hydroxybenzaldehyde.

Abstract: The invention relates to a system comprising a lock (40) provided with NFC circuits, a mobile phone (32) also provided with NFC circuits, a remote lock management site (18), and a mobile network operator (20). For each lock, the management site generates a unique random algorithm, a unique identifier (PUID) and transport keys and transmits the identifier and the transport keys to a lock manufacturer (16). The mobile network operator receives a unique lock identifier (PUID) from the user and transmits same to the handling site which, in return, transmits the unique random algorithm, the cryptographic key, the transport key and the user key corresponding to the lock to the phone. The phone implements the initial programming of the lock, by loading the unique random algorithm, the cryptographic key and the user key onto the lock and, subsequently, the phone activates a secure cryptographic procedure.
