The modern state of bleaching cottonseed oil

In particular, used oksietilidendifosfonovaya acid as demetallization of solomasov. Effective in terms of practical application. Aqueous solutions of this acid are good extractants of transition metal cations, due to their binding in cyclic complexes, the stability of which is comparable and exceeds that in combination with citric acid. The main technological methods of obtaining solid vegetable oils is hydrogenation in combination with and without transesterification. Scientific and practical aspects of these processes are described in the works.
