Pseudo-saccharin chloride

Pseudo saccharin chloride (II) is prepared by the action of phosphorus penta-chloride upon saccharin (I)  [Pg.978]

The procedures for the preparation of a number of azo dyestuffs are described in Sections IV, 76-1V,82 these include the indicators methyl orange and methyl red. Experimental details for the preparation of other typical dyestuffs and indicators are given in the following pages. [Pg.979]

This dyestuff is prepared by tetrazotisiiig benzidine and coupling with sodium naphthionate  [Pg.979]

Pseudo-saccharin ethers. Pseudo-saccharin chloride (Section VII,26) reacts with alcohols to give ethers (0 alkyl derivatives of saccharin) ... [Pg.266]

Heat a little pseudo-saccharin chloride with excess of the anhydrous alcohol in a test-tube until hydrogen chloride is no longer evolved. Recrystallise from alcohol or other organic solvent. [Pg.266]

Pseudo-saccharin ethers. When pseudo-saccharin chloride is heated with an excess of a phenol, 0-aryl derivatives of saccharin are produced (compare Section 111,27, 7). [Pg.684]

Heat 0 5 g. of pseudo-saccharin chloride with an excess of the phenol to 125-140° for 15-20 minutes hydrogen chloride is evolved. Wash the product with dilute sodium hydroxide solution and then with water. Recrystallise the derivative from ethanol. [Pg.684]
