Agitation: Agitation is not required in the bath other than to free entrapped air bubbles. However, moderate agitation, either mechanical or . with clean air, improves coating uniformity and accelerates coating reaction slightly. Ventilation: Adequate local ventilation is required. SOLUTION MAKE-UP. 1. Fill tank ¾ full with water. 2.

The reactivity of these compounds is somewhat similar to that of the azolonium ions, particularly when cationic species (18 → 19) are involved.However, although typical reactions are with nucleophiles, an intermediate 20 can eliminate HOE, where E is an electrophile added to the N-oxide, to give the simple α-substituted azole 21, for example, benzimidazole 3-oxides are readily converted ...
