Question

Outline the synthesis of either methyl
orange or malachite green.​

Answer 1

The pigment can be prepared from the mineral malachite by grounding, washing and levigating the raw material.

Malachite can also be prepared in the laboratory by a reaction of copper (II) sulfate and sodium carbonate. The artificial form is sometimes called green verditer.

Malachite green is a triaryl methane dye which is used as a dyestuff and controversially as an antimicrobial in aquaculture.

It can be prepared by condensing benzaldehyde and dimethylaniline in the molecular ratio 1:2 in the presence of sulphuric acid.
