Calcium magnesium acetate : ウィキペディア英語版 | Calcium magnesium acetate Calcium magnesium acetate (CMA) is a deicer and can be used as an alternative to road salt. It is approximately as corrosive as normal tap water, and in varying concentrations can be effective in stopping road ice from forming down to around (its eutectic temperature). CMA can also be used as an H2S capture agent. ==Production== CMA can be produced from a reaction of a magnesium/calcium compound with glacial acetic acid. If it is reacted with dolomite or dolomitic lime, acetic acid does not need to be concentrated to produce CMA. Acetic acid production requires the fermentation of organic material which must be carried out at a pH around 6.0. Separating agents used to recover acetic acid must therefore maintain a high capacity while within this pH range. Amberlite LA-2 in 1-octanol diluent maintains nearly full capacity up to a pH value of 6.0 and is readily regenerated by aqueous, slaked dolomitic lime to form CMA, making it a good acetic acid separating agent for CMA production.
