बेंजीडीन इसके अंग्रेजी अर्थ का उदाहरण

Treatment of this hydrazine with mineral acids induces a rearrangement reaction to 4,4'-benzidine.

The benzidine rearrangement, which proceeds intramolecularly, is a classic mechanistic puzzle in organic chemistry.

In terms of its physical properties, 4,4'-benzidine is poorly soluble in cold water but can be recrystallized from hot water, where it crystallises as the monohydrate.

Conversion of benzidine to the bis(diazonium) salt was once an integral step in the preparation of direct dyes (requiring no mordant).

In the past, benzidine was used to test for blood.

An enzyme in blood causes the oxidation of benzidine to a distinctively blue-coloured derivative.

A variety of derivatives of 4,4’-benzidine are commercially produced on the scale of one to a few thousand kilograms per year, mainly as precursors to dyes and pigments.

As with some other aromatic amines such as 2-naphthylamine, benzidine has been significantly withdrawn from use in most industries because it is so carcinogenic.

In August 2010 benzidine dyes were included in the U.

Also in 1945, Dewar devised the then novel notion of a π complex, which he proposed as an intermediate in the benzidine rearrangement.
