WebYou can prepare 0.1N solution as below; Take 192.12/30=6.4040 gram citric acid in a 1000 mL measuring flask. Add some distilled water to it and dissolve it by shaking . Now, add more water up to ... WebWhen heated to 175 °C, it is partially converted to aconitic acid by elimination of water, and to acetonedicarboxylic acid by the loss of carbon dioxide and water. At temperature above 175 °C, citric acid yields an oily distillate, which crystallizes as itaconic acid. Further heating yields a non-crystallizable oil which is citraconic anhydride.

Citric acid: A green cross-linker of biomaterials for …

WebIn past few years, citric acid has emerged as a non-toxic crosslinking agent for the preparation of the hydrogels[16,17]. At sufficiently high temperatures, citric acid forms a cyclic anhydride and esterifies the hydroxyl groups present on the adjacent polymer chains. This leads to the formation of crosslinks. Carboxymethylcellulose (CMC) is a ...
