diazo

Definitions

Examples

• Ordinarily the diazo appears a little earlier than the Widal reaction—about the fourth or fifth day—but it may be delayed.

• The result is a diazo-salt; aniline, for example, giving diazobenzene chloride, and toluidine diazotoluene chloride.

• A new phase in the technology of tar-products was entered upon when Witt caused a diazo-salt to act upon diamidobenzene.

• When the para-position is occupied, the diazo group takes the ortho-position.

• The constitution of the isomeric diazo hydroxides has given rise to much discussion.
