O-Sulfobenzoic imide

F) Preparation of Sulfonphthaleins. The preparations described involve (1) hydrolysis of o-sulfobenzoic imide (saccharin) to the ammonium salt of o-sulfobenzoic acid (2) preparation of o-sulfo-benzoic anhydride (3) preparation of phenolsulfonphthalein (phenol red) (4) bromination of phenolsulfonphthalein to tetrabromo derivative (bromophenol blue) (5) preparation of o-cresolsulfon-phthalein (cresol red) (6) bromination of o-cresolsulfonphthalein to the dibromo derivative (bromocresol purple)The equations for the steps are ... [Pg.337]

Piroxicam Piroxicam, 1,1 -dioxid-4-hydroxy-2-methyl-iV-2-pyradyl-2//-1,2-benzothiazine-3-carboxamide (3.2.78), is synthesized from saccharin (3.2.70). Two methods for saccharin synthesis are described. It usually comes from toluene, which is sulfonated by chlorosulfonic acid, forming isomeric 4- and 2-toluenesulfonyl chlorides. The isomeric products are separated by freezing (chilling). The liquid part, 2-toluenesulfonyl chloride (3.2.68) is separated from the crystallized 4-toluenesulfochloride and reacted with ammonia, giving 2-toluenesul-fonylamide (3.2.69). Oxidation of the product with sodium permanganate or chromium (VI) oxide in sulfuric acid gives saccharin—o-sulfobenzoic acid imide (3.2.70) [123-126]. [Pg.51]
