Carbon Dioxide → Zinc sorbate

참여 물질

반응 단계

224 g sorbic acid were added to 1,000 ml ethanol. While stirring, 117 g basic zinc carbonate was added incrementally at room temperature. The mixture formed a readily stirrable suspension. At room temperature, stirring was continued and, after a short delay, the formation of CO2 started which showed that the reaction was occurring. After 24 hours, enough zinc sorbate had formed so that a firm mass had formed. In a rotary evaporator, the ethanol was drawn off at 60° under vacuum. A white mass of zinc disorbate was recovered and ground in a mill.
