METHOD OF SYNTHESIS OF NONDUSTING AND NONCAKING FORMS OF ALKYLXANTHOGENATES OF ALKALINE METALS Russian patent published in 2002 - IPC

Abstract RU 2186766 C1

FIELD: chemical technology. SUBSTANCE: invention relates to a method of synthesis of alkylxanthogenates of alkaline metals by interaction of alkali, hydrogen sulfide and aliphatic alcohol of the general formula ROH where R means C2H5, n- (or iso-) C3H7, C4H9 in the presence of water using a waste production (resin) captax as an addition decreasing dusting and caking degree and product odor threshold. The latter is added in the amount 0.1-1.0 wt.% to reaction mass on the stage of alcoholate preparing or before feeding to drying directly and it is dissolved preliminary in sodium (potassium) hydroxide an aqueous solution. Obtained xanthogenate samples using resin captax have no specific unpleasant odor practically by data of an organoleptic evaluation and retain commercial form. EFFECT: improved method of synthesis. 2 cl, 1 tbl, 5 ex
