Detailed Description:
Cas No. :9005-38-3 Property
Sodium Aalginate (C5H7O4COONa)n, also called algin, is one kind of electrolyte of organic macromolecule among algae of brown algae types, such as kelp, as principal components of cell membrane with other substances. Chemical components of Sodium Alginate belong to carbohydrate and it only contains free carboxyl (-COONa) in contrast with starch and fibrin. At the same time, it is one kind of chain type macromolecule heteropolymer brought by copolymerization between mannuronic acid and guluronicacid.

Sodium Alginate does not dissolve to methanol, ethanol, acetone and chloroform; dissolve to sodium hydroxide liquid and water; monatomic base alkali salt, such as soduim salt and sylvite, as well as ammonium salt, magnesium salts and mercury salt all dissolve to water and become into thick liquid. Multivalent metal salt of algin does not dissolve to water, except magnesium salts and mercury salt.
