    摘要: A process for the preparation of phenol-phthalein wherein phenol and phthalic anhydride are reacted in the presence of a crosslinked sulfonic cation exchange resin in the acid form and wherein the water content of the reaction mixture is reduced by the use of aryl phosphites.The sulfonic cation exchange resin can be in the macroporous form or in the gel form. The range of useful crosslinking is 4-40 percent for the macroporous resin and 2-16 percent for the gel resin.

    摘要: A METHOD OF PREPARING RADIOACTIVE MONO AND DI-IODOSULFOBROMOPHTHALEIN FOR CLINICAL PURPOSES AND WHEREIN THE RATIO OF DI TO MONOIOSOSUFOBROMOPHTHALEIN CAN BE CONTROLLED IS DISCLOSED. NO SEPARATION AND PURIFICATION OF THE COMPOUNDS IS REQUIRED FOR THEIR USE IN CLINICAL DIAGNOSTIC PROCEDURES. THE COMPOUNDS, PARTICULARLY THE MONOIODO COMPOUND, OFFER A NUMBER OF ADVANTAGES IN COMPARISON TO SULFOBROMOPHTHALEIN WHEN USED FOR BIOLOGICAL INVESTIGATION.
