Calcium Lignosulfonate 8061-52-7

Calcium lignosulfonate (CAS NO. 8061-52-7)is a lignosulfonate compound that contains calcium as a cation. It is derived from lignin, a natural polymer found in the cell walls of plants.

Here are some key points about calcium lignosulfonate:

  1. Chemical Composition: Calcium lignosulfonate is primarily composed of lignosulfonic acid salts derived from the sulfite pulping process. It consists of lignin molecules modified with sulfonate groups and calcium ions.
  2. Solubility: Calcium lignosulfonate is soluble in water and forms a solution in which the calcium ions and lignosulfonate molecules are dispersed.
  3. Physical Properties: Calcium lignosulfonate is typically a brown to dark brown powder or granules. The exact appearance may vary depending on the manufacturing process and the specific product grade.
