A process for preparing a carboxylic acid, including a step of bringing at least one vicinal diol or at least one vicinal polyol into contact with an atmosphere including oxygen, and a catalyst, and in the absence of additional solvent.

Process for preparing a carboxylic acid

A process for preparing a carboxylic acid, by oxidative cleavage of at least one vicinal diol, or an epoxide, wherein the reaction is carried out in the presence of a catalyst and of an oxidizing agent and in the absence of solvent.

Process for preparing a carboxylic acid from a diol or from an epoxide by oxidative cleavage

The invention relates to a method for producing a compound of fonnula (I), comprising the reaction, in the presence of a catalytic system comprising a single rare earth oxide or a mixture of rare earth oxides, of an alkyl carbonate or an alkylene carbonate with a polyol of fonnula (II), wherein p is a whole number between 2 and 10.

Method for producing polyglycerol (poly)carbonate

Disclosed is a method for preparing, by transcarbonation, a compound of formula (I), including reacting a polyol of formula (II) with an alkyl carbonate or an alkylene carbonate in the presence of a catalytic system consisting of a catalytic entity selected from among the rare earth oxides or the mixtures thereof, and optionally an inert substrate.

Method for preparing alcohol carbonate using rare earth oxides as catalysts

The invention relates to the use of glycerol ethers as agents that activate the biological effects of at least one substance selected from a herbicide, fungicide or insecticide. The invention essentially relates to the use of glycerol ether as an agent that activates the biological effects of at least one substance selected from a herbicide, or fungicide or insecticide, said glycerol ether having formula (1), wherein Rrepresents an alkyl group having between 1 and 18 carbon atoms and Rrepresents a hydrogen atom or an alkyl group having between 1 and 18 carbon atoms, preferably a methyl or ethyl group. The invention also relates to a phytosanitary composition containing one such glycerol ether, as well as to a phytosanitary treatment method using said composition.

Use of glycerol ethers as activators of the biological effects of a herbicide, fungicide or insecticide substance
