Information @ a Glance

General

  • 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 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.

Applications

  • 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. It is used as a fixing agent in photography, as a liquefying agent in animal hide glue, as an insecticide, as a textile-treating agent, and as an intermediate to produce other compounds.

  • 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.

Technology

  • The three crystals of thiourea family shows Zinc Thiourea Chloride (ZTC), Zinc Thiourea Sulfate (ZTS) and Bisthiourea Cadmium Chloride (BTCC) were grown from aqueous solution by slow evaporation technique. It was found that the BTCC has lowest dielectric constant among three metal complexes of thiourea crystals (ZTC, ZTS and BTCC), therefore it can be used for high speed electro-optic modulation.

  • 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.

Report

  • 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.
