Description of key information

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE, study for Stability in organic solvents and identity of relevant degradation products is only required if stability of the substance is considered to be critical.
Solvents are substances that are capable of dissolving or dispersing one or more other substances. Organic solvents are carbon-based solvents (i.e., they contain carbon in their molecular structure).
Reaction mass of SEX is an organosulfur compound. Xanthate salts are produced by the reaction of an alcohol with sodium or potassium hydroxide and carbon disulfide:
ROH + CS2 + NaOH → ROCS2Na + H2O
Reaction mass of SEX is a member of group of the alkali metal xanthates.They are not particularly soluble in nonpolar solvents, eg, ether or ligroin.Potassium isopropyl xanthate is soluble in acetone to ca 6 wt %, whereas the corresponding methyl, ethyl,n-propyl, n-butyl, isobutyl, isoamyl, and benzyl [2720-79-8] xanthates are soluble to more than 10 wt %.

Its functional groups indicate no solubility in common organic solvents. Solubility in organic solvents is not considered critical. (Ref. 1)
Reactivity
Hygroscopic and reacts with water to form ethyl alcohol, sodium carbonate, trithiocarbonate and carbon disulphide. Susceptible to oxidation and reacts with oxidising agents to form dixanthogens. Incompatible with oxidising agents (eg. hypochlorites) and acids (eg. nitric acid).
Therefore testing for s Stability in organic solvents does not need to be performed.
