Abstract: Prepn. of mono- and di-carboxylic acids from unsatd. fatty acids and/or derivs., comprises: (i) oxidising an unsatd. fatty acid, in the form of an acid and/or ester, with hydrogen peroxide in presence of a metal oxide or a carboxylic acid, opt. with a ruthenium catalyst; (ii) reacting the mixt. with nitric acid in presence of a vanadium catalyst, opt. with a co-catalyst; and (iii) recovering the mono- and di-carboxylic acids. The starting material is pref. a fatty acid with at least one double bond, an animal fat or oil, a vegetable oil, an ester of a pptd. fatty acid and is pref. oleic, colza, sunflower and soya oil. The ruthenium catalyst is pref. present in amt. of 1-35 % w.r.t. H2O2. H2O2 may be used with a gp. VIa metal catalyst, esp. a W and/or Mo catalyst in amt. of 1-35 (pref. 3-10) %, w.r.t. H2O2. The vanadium catalyst may be a V halide, a V oxide, a V oxyhalide, a V or vanadyl sulphate, an alkali metal or ammonium vanadate, or V acetylacetonate. The optional V co-catalyst may be based on a Gp. VIIa or VIII metal. A stoichiometric amt. of H2O2 or a 0-50 % excess is used with a carboxylic acid in a hydrogen peroxide : carboxylic acid molar ratio of 10-500 (pref. 10-40) %.

Abstract: Process for the preparation of an optically active 2-chloropropionate ester of formula: R being an optionally substituted hydrocarbyl residue, from an optically active lactate of formula the said process being characterised in that the said lactate (I) is brought into contact with phosgene and a compound chosen from aliphatic amides, aliphatic lactams and aliphatic ureas. Use of the process for the manufacture of intermediates which are useful in the agrochemical industry.
