Propionate ion → Zinc Acetate

Participants

Reaction Steps

The solution and method according to the present invention use the principle of the dissolution of the conductive powder (e.g. zinc oxide) and of the organic matrix of the thermal grease. The electronic card is treated with a substantially water-free alcoholic solution of a neutral ammonium salt of organic acid (e.g. ammonium acetate or propionate). The ammonium salt (e.g. ammonium acetate) reacts with zinc oxide giving zinc acetate, that are soluble in alcohol, while the organic matrix (e.g. polyether polyol polymers) is dissolved by the alcohol (e.g. isopropanol).
