PURPOSE: To prepare the subject compd. useful as an intermediate for dyestuff synthesis of reactive dyestuffs by cleaving reductively a specified disazo/disazoxy dyestuff and separating the compd. as a slightly water-soluble complex betaine. CONSTITUTION: Disazo/disazoxy dyestuff of formula I [B is a direct bond or a crosslinking member; (v), (w), v+w, (x), (y) and x+y are each 0 or 1] is cleaved reductively under pressured hydrogen to produce a compd. of formula II. The compd. of formula II is oxidized and precipitated, then separated as a slightly water-soluble complex betaine to obtain a compd. of formula III. It is preferable that the compd. of formula II is tetra-azotized and coupled with 2-(2-hydroxyethyl)mercapto-N-(2-hydroxyethyl)-aniline to obtain a compd. of formula IV, then the obtained compd.) of formula IV is oxidized to obtain a compound of formula I.

Software agents are assigned goals in accordance with network policies that define a desired operational characteristic of a computer network. A software agent achieves its assigned goal by executing a predefined task. An assigned goal may be dynamically modified as necessary based on the actual operational characteristics of the network. The software agent may request further policy if it cannot achieve its assigned goal by performing the predefined task.
