P-Rosaniline hydrochloride

Preparation of SchlfT s reagent. Method 1. Dissolve 0- 2 g. of pure p.rosaniline hydrochloride in 20 ml. of a cold, freshly-prepared, saturated aqueous solution of sulphur dioxide allow the solution to stand for a few hours until it becomes colourless or pale yellow. Dilute the solution to 200 ml. and keep it in a tightly, stoppered bottle. If the bottle is not adequately stoppered, the reagent will gradually lose sulphur dioxide and the colour wUl return. The solution keeps well if not unnecessarily exposed to light and air. 

A rapid test for glycol in motor oil involves testing colorimetrically for the formaldehyde product of the cleavage with p-rosaniline hydrochloride and sulfurous acid. A wine-colored, quinoid-type dye forms. 

Schiff s reagent is prepared by dissolving 0.1 g Basic Fuchsin (p-rosaniline hydrochloride) in too mL of water and then adding 4 mL of a saturated aqueous solution of sodium bisulfite. After I h add 2 mL of concentrated hydrochloric acid. 

Sduff s fuchsin aldehyde reagent. Dissolve 1 g of fuchsin (p-rosaniline hydrochloride) in 200 ml of water, with gentle warming. Cool and saturate with sulfur dioxide. Allow to stand for several hours. Add 1 g of decolorizing carbon, shake, filter, and dilute with water to 1 liter. 

A manifold system for the simultaneous determination of SO2 and CO2 in wine has been described [2]. The reaction with p-rosaniline hydrochloride/formaldehyde makes a basis of spectrophotometric measurement (A. = 578 nm).
