- Thiourea is an
organic compound of carbon, nitrogen, sulfur and hydrogen, with the
formula CSN2H4 or (NH2)2CS. It is similar to urea, except that the
oxygen atom is replaced by a sulfur atom.
- Thiourea occurs in
the form of white, shiny crystals. It is soluble in ethanol, and
ammonium thiocyanate solution and it is almost insoluble in ether.
Thiourea also called Thiocarbamide
- Thiourea can be
prepared from ammonium thiocyanate but more commonly is synthesized by
the reaction of hydrogen sulfide with calcium cyanamide in the presence
of carbon dioxide.
- Thiourea is used in
photo-sensitive papers, in boiler-water treatment, and as a chemical
intermediate. It is also used as a vulcanization accelerator, as a metal
corrosion inhibitor for pickling solutions, in plating baths for metals,
in nylon and textile treatments, and in the production of
resins.
- Thiourea is used
directly in ore filtering, metal refinery and cleaning, isomerization
catalyst and as an additive in fertilizers, drilling auxiliaries,
light-sensitive photocopy paper and explosives.
- Thiourea and its
derivatives are versatile intermediates for the synthesis of modified
thermosetting resins, thiourea dioxide, dyes, flame retardants,
vulcanization accelerators, plant protection agents, pesticides, amino
resins, peptizing agents, fungicides, hair preparations, dry cleaning
chemicals, corrosion inhibitors and thiazole drugs.
- Technologies such as
heap leaching have established themselves as economical methods for the
recovery of precious metals from low grade mineral deposits.
Amalgamation, cyanidation, and thiourea leaching are some of the
methodologies that are used to separate gold from their ores.
- Commercially
available thiourea of chemically pure grade was recrystallized from
alcohol and the recrystallized material was fed or injected. It melted
at 178-179” and contained 41.79 per cent of sulfur and 36.55 per cent of
nitrogen.
- U.S. exports of
thiourea, thiourea dioxide, thiocarbamates, thiurams, and other related
chemicals ranged from approximately 300,000 to 500,000 lb in past years.
Among recently, U.S. exports were approximately 38 million
lb.
- The global annual
production of thiourea is around 10,000 tons. About 40% is produced in
Germany, another 40% in China, and 20% in Japan.
