One person has been killed and four others injured in a burst fire at zhaoyuan jinheng chemical co LTD in xinzhuang town, yantai city, shandong province.
According to the preliminary investigation and analysis, the direct cause of the accident is: leakage of water in the jacket of the tetraphenyltin reaction kettle or excessive water content of the raw material stannic chloride and the solvent xylene, violent reaction to meet the incomplete reaction of the metal sodium to produce hydrogen, and the air to form an explosive mixture of gases, when static electricity and other ignition sources occur.
Through the state industrial and commercial information website query, the explosion of the main production of tin chloride triphenyl (also known as tin acetate triphenyl), tin acetate triphenyl, tin hydroxide triphenyl;
Tin triphenylacetate is commonly known as daoqu jing, which is mainly used to prevent rice blast disease, daoqu disease, striped spot disease, sugar beet brown spot disease, potato late blight, and has a special control effect on snails, algae and water snails, which is better than a kind of medicine bailuoban.
After the March 21 incident, most domestic chemical enterprises took the initiative to carry out hidden dangers investigation, but some enterprises still had hidden safety problems.

Many provinces emergency deployment clear investigation time
On March 22, the emergency management department held a symposium on the safety work of chemical industry (hazardous chemicals) along the Yangtze river in wuhan, hubei province, attended by provincial emergency management departments in hubei, Shanghai, anhui, jiangxi, hunan, chongqing, sichuan and yunnan.At the meeting, it was proposed to strengthen the screening, rectification and risk prevention and control of potential safety hazards, pay close attention to the implementation of the main responsibility of enterprises for production safety, seriously pursue accountability, and accelerate the construction of emergency facilities.
At the same time, jiangsu, hebei, liaoning, anhui, hainan, shandong, sichuan, guizhou, fujian and other provinces, emergency deployment of hazardous chemicals production safety hidden trouble investigation and rectification work.According to incomplete statistics, up to now, more than 20 provinces in China have carried out the work of hazardous chemicals safety rectification.
At the same time, the local chemical safety regulation work set a time requirement.
A week-long inspection of hazardous chemicals was launched in Beijing on March 24.
Shandong requires all enterprises of hazardous chemicals and explosion-related dust in the province to complete self-examination and self-correction of safety risks within 3 days, and all emergency management departments of cities and counties should complete the inspection of relevant enterprises within a week.

Carpeting the whole process of chemical production
In addition, the state council's safety commission also called for in-depth investigation and rectification of safety risks in coal mines, non-coal mines, road traffic, fire control, construction and other industries to prevent all kinds of accidents.
Emergency notice issued by jiangsu province, focusing on the investigation of safety risks in the production, storage and operation of hazardous chemicals;
Qinghai province committee office issued an urgent notice, requiring the deepening of road traffic, dangerous chemicals, mining, fire protection, building construction and other special campaigns, immediately organization of chemical enterprises in qinghai province and joints between urban and rural areas, rural, remote courtyard, old workshop and other places to "carpet, trawl, full coverage" hidden perils.

Raw material prices may rise again
No matter be chemical industry of water of sound water chemical industry 16 chemical companies are forced stop work, or countrywide each district rectify check, a large number of chemical plants stop production or delay production, had caused the concussion of whole chemical industry market apparently.The price of chemical products is in chaos, which directly leads to a surge of price increase due to the shortage of goods.
It is understood that the herbicide market, glyphosate glycine manufacturers quote to 25,000 yuan/ton or less;The downstream terminal of glyphosate was gradually started, and the quotation was within 147,000 yuan/ton.At the same time, the supply of many selective herbicides is relatively tight, such as cyperazine, oxaoxone, spermaquinolone, nicosulfuron and pentafluorooxalamine.
In terms of pesticides, abamectin manufacturers have a strong willingness to raise prices, and nicotinoids are mainly stable. Malathion, propylbromophosphorus, diazarin, acarate and biphenylhydrazine are limited by the limitation of starting production and high prices.
As for fungicides, due to the pressure of environmental protection, the enterprise started less and the supply was relatively tight.Pyrazole ester manufacturers fierce competition, the downstream inventory gradually digestion, market wait-and-see mood is serious, the market price reported 190,000 yuan/ton.
Will tell to each district dealer, the biggest worry is whether stock up on goods, but what need to remind is, dealer can buy goods according to local condition, before rising in price tide, polish eye, want reason to deal with, can ask cooperative manufacturer specific circumstance directly, avoid to fall into the trap that certain manufacturer takes this to hype a price!
Both explosions belong to a big classification industry, which shows the importance of safe production. It is estimated that the situation of safe production will be more severe in the future, and it is called on enterprises to pay attention to safe production to avoid the occurrence of tragedy.The price of pesticides may not be very optimistic for distributors and growers. I hope you can pay more attention to your upstream enterprises and make preparations in advance.
