Here, we bridge the gap between carbon mineralization and laundry detergent builder with sodium oxalate. Daily laundry can help mineralize carbon dioxide. First, we screen an environment-friendly process to produce sodium oxalate, using CO as a raw material. Then, we evaluate the properties of sodium oxalate as a detergent builder and prove the formation of calcium oxalate under laundry conditions. Our data suggest that sodium oxalate has excellent calcium-removing properties. Detergents based on sodium oxalate have good detergency. Furthermore, solid calcium oxalates (calcium oxalate monohydrate or calcium oxalate dihydrate, which has good stability in water and thermal stability), is obtained from washing waters. These results demonstrate the possibility of using sodium oxalate as detergent builder. The whole process can transform the greenhouse gas CO into commodity chemicals and can mineralize carbon.
在这里，我们用草酸钠填补了碳矿化和洗衣剂助剂之间的空白。日常洗衣有助于将二氧化碳矿化。首先，我们筛选出一种使用 CO 作为原料的环保方法来生产草酸钠。然后，我们评估了草酸钠作为洗涤剂助剂的性能，并证明了在洗衣条件下形成草酸钙。我们的数据表明，草酸钠具有出色的除钙性能。基于草酸钠的洗涤剂具有良好的清洁性能。此外，从洗涤水中得到了固体草酸钙（一水合草酸钙或二水合草酸钙，在水中具有良好的稳定性和热稳定性）。这些结果表明了使用草酸钠作为洗涤剂助剂的可能性。整个过程可以将温室气体 CO 转化为商品化学品，并实现碳矿化。
