METHOD OF OBTAINING SALTS OF EPOXIDISED CARBOXYLIC ACID Russian patent published in 2013 - IPC C07D301/16 C07D303/38 C08K5/1515 

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining salts of epoxidised carboxylic acid, which are applied as stabiliser and plasticiser for halo-polymers, in production of lacquers, surface-active compositions, which are applied as flotation agents, as well as additives in production of tyre cord. Method is realised in two stages: epoxidation and neutralisation. Epoxidation of unsaturated carboxylic acids is realised at interaction of hydrogen peroxide in quantity 6.0-40% wt, formic or acetic acid in quantity 5.0-50% wt, surface-active substances alkylbenzyldimethylammonium chlorides in quantity 0.1-10% wt, and heterogeneous melt aluminonickeltitanium catalyst in quantity 0.1-5.0% wt. Neutralisation of epoxidised carboxylic acids is realised by hydroxides of lithium, sodium, potassium, calcium and zinc at temperature 80-90°C.

EFFECT: increased output of target salts and improvement of their plasticising and thermo-stabilising properties.
