| Hazard Information | Back Directory | [General Description]
Dark brown liquid. | [Reactivity Profile]
2,3-XYLIDINE(87-59-2) reacts with strong oxidizing agents and hypochlorite bleaches . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides. | [Air & Water Reactions]
Slightly soluble in water. | [Fire Hazard]
This compound is combustible. | [Chemical Properties]
brown liquid | [Uses]
Reagent used in the preparation of non-steroidal anti-inflammatory drugs, dyes and pesticides. | [Purification Methods]
Purify vic-xylidine by conversion into a derivative (see below), recrystallise the derivative, decompose the derivative with aqueous NaOH and fractionally distil the liquid base. The acetyl derivative has m 135o (from EtOH), and the formyl derivative has m 102o (from EtOH). [Beilstein 12 H 1101, 12 III 2438, 12 IV 2497.] |
