Thiourea is widely used and my country is the world’s major producer and consumer country.

Thiourea is an organic sulfur-containing compound with the chemical formula CH4N2S. It looks like shiny white crystals and tastes bitter. It is easily deliquescent in the air. It is soluble in cold water, ethanol, and slightly soluble in ether. Thiourea has broad application prospects in the fields of medicine, pesticides, petrochemicals, dyes, rubber, mining, electroplating and other fields. It is a widely used fine chemical raw material.

There are two main methods for producing thiourea. They are the one-step method, which refers to the method of directly passing hydrogen sulfide gas into calcium cyanamide slurry to generate thiourea; the two-step method, which refers to using sulfuric acid or hydrochloric acid and sodium sulfide as raw materials. , a method of generating barium chloride, barium sulfate, and hydrogen sulfide gas through chemical reactions, and passing the hydrogen sulfide gas into the lime slurry to generate thiourea. Among them, the one-step method has the advantages of short process flow, simple technology, and high output rate. It is currently the main method used by domestic and foreign companies to produce thiourea.

Thiourea has a wide range of uses. In the pharmaceutical field, it can be used in the production of sulfonamide drugs (thiamine thiazole), methionine and other drugs; in the electroplating field, it can be used in the production of electroplating additives to enhance the electrodeposition rate and improve the uniformity of the plating. properties and gloss, and prevent hydrogen embrittlement; in the field of rubber, it can be used in the production of rubber vulcanization accelerators; in the field of pesticides, it can be used as germination accelerators, fungicides (seed dressing spirit), herbicides (acetochlor, Tekusatsu), fertilizer and other product production scenarios; in the chemical industry, it can be used in the synthesis of heterocyclic compounds containing sulfur atoms or sulfhydryl groups.

According to the “Thiocarbamide Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2023-2028” released by the Industrial Research Center, 2022 The global thiourea market size has reached US$230 million in 2018, a year-on-year growth of 3.1%. Among them, China is the main producer of thiourea in the world. In 2022, domestic thiourea consumption will account for more than 40% of the global total.

In addition, my country is also the world’s largest producer of thiourea, with a large number of manufacturing companies, including Guizhou Hongkai Chemical, Shandong Yifengsheng New Materials, Shandong Xinke Environmental, Shandong Wantong Holdings, Zhejiang Ruihua Chemical, Xi’an Long Science, Hebei Sinochem International New Materials, Guizhou Tianzhu Wuzhou Chemical, Guizhou Hongxing Development, Zaozhuang Yongli Chemical, Hebei Xinji Chemical Group, etc. Moreover, Guizhou Hongkai Chemical, Shandong Yifengsheng New Materials, Shandong Xinke Environmentalization, Shandong Wantong Holdings and other companies already have 10,000-ton thiourea production capacity, and domestic thiourea production capacity leads the world. In 2022, domestic thiourea production capacity will account for nearly 80% of the global total production capacity.

Industry analysts said that thiourea is a widely used basic chemical raw material in pesticides, medicines and , chemical industry, electroplating, rubber and other fields, it has broad market development prospects. With the rapid development of the domestic economy, my country’s demand for thiourea continues to increase, and it has now become a major producer in the world. At the same time, my country’s chemical industry has a good foundation. With the gradual release of the production capacity of local thiourea companies, my country has become the world’s largest producer, and the industry The overall development trend is good.
