A continuous process for the oxidative cleavage of vegetable oils containing triglycerides of unsaturated carboxylic acids, to obtain saturated carboxylic acids, comprising feeding to a first continuous reactor a vegetable oil, an oxidizing compound and catalyst capable of catalyzing the oxidation reaction of the olefinic double bond to obtain an intermediate compound containing vicinal diols: feeding to a second continuous reactor said intermediate compound, a compound containing oxygen and a catalyst capable of catalyzing the oxidation reaction of the vicinal diols to carboxylic groups, to obtain saturated monocarboxylic acids (i) and triglycerides containing saturated carboxylic acids with more than one acid function (ii); separating the saturated monocarboxylic acids (i) from the triglycerides (ii); hydrolyzing in a third reactor the triglycerides (ii) to obtain glycerol and saturated carboxylic acids with more than one acid function; and purifying said saturated carboxylic acids by fractioned crystallization by means of wash column (melt crystallization).

Continuous process of oxidative cleavage of vegetable oils

The present invention relates to a process for the synthesis of 5-hydroxymethyl furfural (HMF) comprising the steps of: 1) dehydrating at least one saccharide selected from monosaccharides having 6 carbon atoms and disaccharides, oligosaccharides or polysaccharides formed from units having 6 carbon atoms or mixtures thereof in the presence of at least one quaternary ammonium salt RR'NX; in which: &#x2014;R, which is the same or different, represents a C-Csubstituted or unsubstituted alkyl group; &#x2014;R&#x2032; belongs to the group consisting of: hydrogen, C-Csubstituted or unsubstituted alkyl group, monocyclic substituted or unsubstituted aryl group; &#x2014;Xrepresents an anion selected from chloride, bromide, iodide, fluoride, hydroxide, BFand PF; at a temperature of between 80 and 120&#xb0; C., removing water from the reaction medium (dehydration stage) and obtaining a reaction mixture comprising the quaternary ammonium salt, HMF, any unreacted saccharide and having a water content of less than 30% by weight relative to the weight of the product HMF; 2) separating HMF from the said reaction mixture (separation stage).
