Thiocarbamide Usage And Synthesis
Description Thiourea appears as white crystal/powder, is combustible, and on contact with fire, gives off irritating or toxic fumes/gases. Thiourea is a reducing agent used primarily in the production of bleached recycled pulp. In addition, it is also effective in the bleaching of stone groundwood, pressurised groundwood. Thiourea undergoes decomposition on heating and produces toxic fumes of nitrogen oxides and sulphur oxides. It reacts violently with acrolein, strong acids, and strong oxidants. The main application of thiourea is in textile processing and also is commonly employed as a source of sulphide. Thiourea is a precursor to sulphide to produce metal sulphides, for example, mercury sulphide, upon reaction with the metal salt in aqueous solution. The industrial uses of thiourea include production of flame-retardant resins and vulcanisation accelerators. Thiourea is used as an auxiliary agent in diazo paper, light-sensitive photocopy paper, and almost all other types of copy paper. Thiourea is used in many industrial applications, including as a chemical intermediate or catalyst, in metal processing and plating, and in photoprocessing.
Chemical Properties Thiourea consists of colorless, lustrous crystals or powder with a bitter taste.
Chemical Properties white crystals or powder
Uses The product is wildly used in pharmaceutical industry, agricultural, chemicals, metallurgical industry, petroleum and so on. It is also main material for producing thiourea dioxide(CH1N2O2S).
Uses Chaotropic agent; strong denaturant. Increases solubility and recovery of proteins
Uses Used in determination of bismuth.
Uses In animal glue liquifiers and silver tarnish removers. Photographic fixing agent and to remove stains from negatives; manufacture of resins; vulcanization accelerator; a reagent for bismuth, selenite ions.
Definition ChEBI: The simplest member of the thiourea class, consisting of urea with the oxygen atom substituted by sulfur.
General Description White or off-white crystals or powder. Sinks and mixes with water.
Air & Water Reactions Water soluble.
Reactivity Profile Thiocarbamide is a white crystalline material or powder, toxic, carcinogenic. When heated to decomposition Thiocarbamide emits very toxic fumes of oxides of sulfur and oxides of nitrogen. Violent exothermic polymerization reaction with acrylaldehyde (acrolein) [MCA SD-85, 1961], violent decomposition of the reaction product with hydrogen peroxide and nitric acid [Bjorklund G. H. et al., Trans. R. Soc. Can.,1950, 44, p. 28], spontaneous explosion upon grinding with potassium chlorate [Soothill, D., Safety Management, 1992, 8(6), p. 11].
Hazard A questionable carcinogen. May not be used in food products (FDA); skin irritant (allergenic).
Health Hazard Poisonous inhaled or swallowed. Irritating to skin; may cause allergic skin eruptions.
Contact allergens Thiourea is used as a cleaner agent for silver and cop- per, and as an antioxidant in diazo copy paper. It can induce (photo-) contact dermatitis.
Potential Exposure Thiourea is used as rubber antiozonant, toning agent; corrosion inhibitor; and in pharmaceutical manufacture; in the manufacture of photosensitive papers; flame-retardant textile sizes; boiler water treatment. It is also used in photography; pesticide manufacture; in textile chemicals.
First aid Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24-48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
Shipping UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
Purification Methods Crystallise thiourea from absolute EtOH, MeOH, acetonitrile or water. Dry it under vacuum over H2SO4 at room temperature. [Beilstein 3 IV 342.]
Incompatibilities Dust may form explosive mixture with air. Reacts violently with acrolein, strong acids (nitric acid). Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
Waste Disposal Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
