Summary of news about Thiourea
Research field:
On March 3, 2025, Zhu Benzhan's research group revealed the molecular mechanism of the accidental production
of · OH by the reaction of small thiourea, a classic · OH scavenger, with H₂O₂, and found that thiourea
and many comrding to the "Global thiourea Market Report 2025-2031" by Juyi Information Consulting,
China's thiourea production in 2024 reached 61,155 tons,
accounting for 76.20% of the global markThe relevant research results were published in Proc Natl Acad Sci USA
and Environ Sci Technol.
et,
and global thiourea producers mainly include Yifeng, Guizhou Hongkai, Haoyi Environmental Protection, etc.
In 2024, the top three global vendors will hold approximately 59.0%pounds containing thiourea structure can
mediate the decomposition of H₂O₂ to produce · OH. Moreover,
the new · OH production system has the advantages of better · OH production capacity, continuous production, wide pH range,
strong water solubility, and low product toxicity.
Market research:
On March 4, 2025, acco market share.
The global thiourea market is expected to rea Shandongch $240 million in 2031 with a CAGR of 7.7% in the next few years.
Project construction: On February 25, 2025, the Weifang Ecological Environment Bureau released the announcement of the acceptance of the environmental impact report of Shandong Yuan Hejiunew Materials Co., Ltd. with an annual output of 12,000 tons of urea sulfur dioxide project, urea sulfur dioxide is an alternative product of insurance powder, with strong reduction, good thermal stability and other characteristics, and thiourea is the main raw material for the synthesis of urea sulfur dioxide.
Battery technology:
On February 9, 2025, it was reported that domestic enterprises in the field of sulfide all-solid-state batteries a new path,
industrial by-product thiourea purification method has been patented, mass production costs or straight down 70%,
is expected to promote the development of sulfide all-solid-state batteries.
On February 25, 2025, a warehouse rented by Chinese citizens in Ayutthaya Province, Thailand,
was found to illegally store a large number of dangerous chemicals, including thiourea, according to Thai law,
storing dangerous goods without permission can be sentenced to up to two years in prison or a fine of 200,000 baht.
