    摘要: A process for the purification of water-soluble non-ionic contrast agents from water-soluble non-ionic impurities involves the steps of (a) injecting a raw water-soluble non-ionic contrast agent solution on a chromatographic column containing non-ionic resins; (b) eluting water-soluble impurities contained in the raw water-soluble non-ionic contrast agent solution with deionized water as a first eluent, and (c) eluting a water-soluble non-ionic contrast agent with alcohol as a second eluent.

    摘要: A process for preparing an angiotensin converting enzyme inhibitor. Phosphorus pentachloride is reacted with the carboxylic acid group of an amino acid to form an acyl chloride hydrochloride. The resulting hydrochloride salt is then coupled with a silylated amino acid in a non-aqueous medium to form a high yield peptide. The peptide is used as an angiotensin converting enzyme (ACE) inhibitor.
