Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.COA of Formula: C4H9NaS

Oxidation of sodium mercaptide with sulfonated cobalt phthalocyanine as catalyst was written by Liu, Ruiting;Xia, Daohong;Xiang, Yuzhi. And the article was included in Preprints – American Chemical Society, Division of Petroleum Chemistry in 2003.COA of Formula: C4H9NaS This article mentions the following:

The oxidation of Na mercaptides by air in alk. solution with CoSPc as catalyst was studied. Effects of various factors, including temperature, structures of mercaptides and concentration of alk. solution, on the oxidation of Na mercaptides were analyzed, which can provide some guides for the design of parameters in LPG sweetening. In the experiment, the researchers used many compounds, for example, Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2COA of Formula: C4H9NaS).
