D-CAMPHOR-10-SULFONIC ACID - Reference Information

EPA chemical information Information provided by: ofmpub.epa.gov (external link)
introduction optically active L-and D-camphor sulfonic acid is an important chiral isomer drug resolution agent. Dextropin can be obtained from natural camphor by brominated sulfonation, or from racemic camphor sulfonic acid by induced crystallization.
preparation preparation with left-handed and right-handed camphor sulfonic acid, separation: adding 23.2kg of racemic camphor sulfonic acid, 18kg of splitting agent composition and 20kg of water while stirring in a 100-liter enamel kettle, mixing and heating to 60-100 ℃ for 1 hour, cooling to 5-10 ℃, and keeping for 1 hour, the double salt of d-camphor sulfonic acid was obtained by filtration, three times the amount of water was added, heated to 60-100°C, the pH value was adjusted to 4-7 with ammonia water, and then cooled to 5-10°C to filter and recover the splitting agent composition. The filtrate is dextrocamphor sulfonate ammonium salt solution with a resolution rate of 99%. The mother liquor with the double salt is added with ammonia water to neutralize to pH 4-7, cooled to 5-10 ℃, and the resolution agent composition is filtered out. The filtrate is a solution of ammonium levoghor sulfonate, and the resolution rate is 100%. Purification: the L-camphor sulfonate ammonium salt solution and the D-camphor sulfonate ammonium salt solution are respectively loaded into chromatography columns A and B, and slowly collected the-column L-camphor sulfonate ammonium salt solution and the B- column D-camphor sulfonate ammonium salt solution. The A and B solutions are respectively evaporated and concentrated to anhydrous by thin film evaporator, then acetic acid and acetic anhydride solvent are added, crystallized, cooled to 5~25 ℃, filtered, dried to obtain white crystal, and the optical purity of L-camphor, the optical purity of dextrocamphorsulfonic acid is 99.7%.
use organic synthesis intermediate, resolution agent.
It can be used as a splitting agent and a catalyst for dipeptide coupling.
