sodium dichromate

Sodium Dichromate can be used in fluoren to fluorenone conversion.

For the tanning of leather, sodium dichromate is first reduced with sulfur dioxide.

Like all hexavalent chromium compounds, sodium dichromate is considered hazardous.

It can be destroyed by sodium dichromate.

Virtually all chromium ore is processed via conversion to sodium dichromate.

In this way, many millions of kilograms of sodium dichromate are produced annually.

It is obtained from the reaction of sodium dichromate with sodium hydroxide.

Sodium dichromate is a chemical compound.

Ammonium acetate and sodium dichromate are used to destroy small quantities of lead azide.

The sodium chromate is reacted with sulfuric acid to produce sodium dichromate.

The sodium dichromate is reduced by carbon to chromium(III) oxide.

The material can react vigorously with reducing materials and is incompatible with sodium dichromate or sulfuric acid.

In terms of reactivity and appearance, sodium dichromate and potassium dichromate are very similar.

Potassium dichromate is usually prepared by the reaction of potassium chloride on sodium dichromate.

Sodium Dichromate is often required as an additive to promote oxidation in certain 'types' of Nitric-based acid baths.

Sodium dichromate is generated on a large scale from ores containing chromium(III) oxides.

Sodium dichromate is sometimes used because of its higher solubility (50 g/L versus 200 g/L respectively).

As I recall, the main ingredients of a chromic acid bath are concentrated sulfuric acid and chromium trioxide or sodium dichromate.

Chromium trioxide is generated by treating sodium chromate or the corresponding sodium dichromate with sulfuric acid:

It involves immersing a zinc or zinc-plated article for 5 to 15 seconds in a chromate solution, typically prepared from Sodium dichromate and Sulfuric Acid.

In 1839, while experimenting with early photographic processes developed that year by William Henry Fox Talbot, Mungo discovered the light-sensitive quality of sodium dichromate.

Sodium dichromate oxidation gave carboxylic acid 25, Diazomethane treatment gave methyl ester 26 and sodium borohydride the allyl alcohol 27.

Strontium chromate is prepared from the reaction of strontium chloride with sodium chromate, or from a reaction between strontium carbonate with sodium dichromate.

Mungo Ponton FRS (20 November 1801 - 3 August 1880) was a Scottish inventor who in 1839 created a method of permanent photography based on sodium dichromate.

Like other chromium(VI) compounds (chromium trioxide, sodium dichromate), potassium dichromate may be used to prepare "chromic acid", which can be used for cleaning glassware and etching materials.
