Copper aspirinate use of copper aspirinate as a pigment in PVC and Polystyrene has also been investigated. Copper aspirinate Copper(II) aspirinate is an aspirin chelate of copper(II) cations (Cu). It is used to treat rheumatoid arthritis. Copper aspirinate can be prepared by several methods. In one route of preparation, an excess of acetylsalicylic acid is dissolved in aqueous sodium carbonate. Sodium hydroxide is not suitable for this purpose, because it will hydrolyse acetylsalicylic acid ("ASA") into salicylic acid and sodium acetate. The resulting solution is then filtered to remove any undissolved acetylsalicylic acid and is mixed with a solution containing Cu cations
Willow Bunch, Saskatchewan Willow Bunch community, settled in what is part of the present-day Jean Louis Légaré Regional Park. Légaré, who married into the Métis community, opened a trading post/store there, and often traded various necessities to the local Métis for bison goods. In the spring of 1881, it was estimated he had around $3,000 worth of bison products in his store. A boy named Édouard Beaupré, better known as the Willow Bunch Giant, was the first child born and baptized in the area in 1881. The forerunner settlement of Willow Bunch was established in 1883, around two miles east of Légaré's store
