MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202631024576 A) filed by West Bengal Chemical Industries Ltd., Kolkata, West Bengal, on March 2, for 'an improved one-pot synthetic process for the preparation of white sodium ascorbyl phosphate.'
Inventor(s) include Sunil Kumar Agarwal; Dr Anup Kumar Kundu; Avijit Sehanobish; Abir Kumar Pal; Mahua Biswas; Dr Pabitra Mandal; Saunak Sarbajna; Shelly Dutta; and Ananya Pal.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an improved and environmentally sustainable process for the preparation of sodium ascorbyl phosphate. The process comprises a single-step, one-pot aqueous phosphorylation of ascorbic acid using trisodium trimetaphosphate under controlled pH conditions at a temperature below 30 C. The method eliminates the needs of intermediate calcium salt formation, uses of catalysts, membrane filtration, ion-exchange resin purification, costly and toxic organic solvents. Upon completion of the reaction, the aqueous reaction mass is directly spray dried to obtain white, high-purity sodium ascorbyl phosphate with a yield greater than 98%. The present process is simplified, cost-effective, industrially scalable, and consistent with the principles of greener chemistry."
