I am attempting to recycle or find a use for chlorodifluoromethane, however I do not want to risk venting it into the atmosphere or exposing myself to hydrofluoric acid. Ideally, I would like to produce chlorine/fluorine salts for safe storage/disposal. Edit: Upon further research, calcium fluoride appears to be a non-toxic salt of fluorine.

Reactions of Group 2 Elements with Acids - Chemistry

Calcium sulfate is slightly soluble, and strontium and barium sulfates are essentially insoluble. When exposed to sulfuric acid, a layer of insoluble sulfate is formed on each of these metals, slowing or stopping the reaction entirely. In the calcium case, some hydrogen is produced, along with a white precipitate of calcium sulfate.

Oilfield metal naphthenate formation and mitigation

Nov 06, 2019· In essence, the naphthenate inhibitor blocks the 2:1 complexation of ARN with calcium ion. 1:1 reaction of ARN acid and divalent calcium ion does not allow for the formation of sticky polymeric naphthenate deposit (Hurtevent and Ubbels 2006). The overall effect is a decrease in the rate of metal naphthenate formation (Hanneseth et al. 2006).
