Methanol is composed of methyl and hydroxyl groups and has the chemical properties of alcohol.Methanol can react with fluorine gas, pure oxygen and other gases and burn violently in pure oxygen to generate water vapor and carbon dioxide 2CH3OH+3O 2=2CO 2+4H 2O. In addition, methanol can also undergo ammoniation reaction (370 ℃~ 420 ℃) NH 3+CH 3OH → CH 3NH 2+H 2ONH 3+2CH 3OH → (CH 3) 2NH+2H 2ONH 3+3CH 3OH → (CH 3) 3N+3H 2O Methanol has the universality of saturated monohydric alcohol,Since there is only one carbon atom, there is a unique reaction.For example, ① it forms crystalline substance CaCl 2 · 4CH 3OH with calcium chloride, forms molecular compound BaO · 2CH 3OH with barium oxide and dissolves in methanol;Similar compounds include MgCl 2 · 6CH 3OHCuSO 4 · 2CH 3OH, CH 3OK · CH 3OH, AlCl 3 · 4CH 3OH, AlCl 3 · 6CH 3OH, and AlCl 3 · 10CH 3OH, etc. 2O+2CO 2 ③ Methanol and chlorineBromine is not easy to react, but it is easy to react with its aqueous solution, and initially produces dichloromethyl ether (CH 2Cl) 2O. Due to the action of water, it is transformed into HCHO and HCl2CH 3OH+2Cl 2=(CH 2Cl) 2O+H 2O+2HCl (CH 2Cl) 2O+H 2O=2HCHO+2HCl ④ Heating with alkali and lime, it produces hydrogen and generates sodium formate CH 3OH+NaOH → HCOONa+2H 2 ⑤ Distilling with zinc powder, decomposition occurs,Generate CO 2 and H 2O2CH 3OH+2O 2 → 4H 2O+2CO 2
[Building Materials Network] Today, the air quality is getting lower and lower due to the haze, and we can't stay outside, but what about the air quality inside?Formaldehyde has always been a major killer of indoor hazards. How to buy wooden doors, floors, paints and wall paints without formaldehyde?Formaldehyde is colorless and tasteless. Only after decoration, if the formaldehyde content seriously exceeds the standard, will there be a pungent smell. As for the new house after decoration
[Building Materials Network] Under the pressure of multiple negative factors, such as the falling oil price, the centralized restart of large methanol production plants, and the continued decline in demand, methanol futures prices fell sharply, the main 1506 contract fell, and the market was pessimistic.At present, downstream demand has entered a seasonal trough period, while the pressure on the supply side has not eased at all. Methanol will be easy to fall but difficult to rise in the future.
[Building Materials Network] Although the overall production capacity planned to be put into operation in 2014 is not large, the methanol industry's devices put into operation in 2013 began to release pressure to the market in 2014.In the first half of 2014, under the influence of high operating rate, import recovery and poor downstream demand, methanol prices continued to decline under pressure.Petroleum and Chemical Industry Planning Institute, China Nitrogenous Fertilizer Industry
[Building Materials Network] According to the 2014 Global Formaldehyde and Resin Analysis Report released by HS Chemical, the operating rate of global formaldehyde devices is still low, but the rapid growth of the downstream resin market is digesting excess capacity.It is expected that in five years, the world will need new formaldehyde production capacity to meet the market demand.IHS Chemical also pointed out that China has become the global
[Building Materials Network] "The performance of methanol market in the second half of 2013 was significantly better than that in the same period of previous years, especially the current market situation can be said to make market people happy." Li Yadong, the sales manager of Sichuan Jiuyuan Agricultural Materials Chemical Co., Ltd., told the Futures Daily that in the second half of 2013, the methanol market continued to gather favorable factors, making the overall market bullish enthusiasm high.At present
[Building Materials Network] With the approaching of high oil prices, methanol fuel and methanol fuel vehicles that have been studied for nearly 30 years have ushered in development opportunities.In order to accelerate the promotion of methanol fuel, standardize the construction of methanol fuel filling stations, and promote the development of methanol related industries, Gansu Provincial Commission of Industry and Information Technology recently issued the Notice on Doing Well in the Pilot Work of Methanol Fuel Promotion (hereinafter referred to as
[Building Materials Network] In response to the public's complaints about the complicated administrative approval procedures for environmental protection, the Shaanxi Provincial Environmental Protection Department has recently checked and sorted out the relevant national environmental protection laws and regulations, greatly simplified the procedures, reduced links, improved energy, served enterprises and the public, and cancelled the approval for the discharge of combustible gases, including converter gas, into the atmosphereMethanol gasoline promotion and methanol gasoline production qualification certificate
[Building Materials Network] Chen Xianjie, the executive vice president of Shaanxi Baojiang New Energy Co., Ltd., a member of the Alcohol Ether Special Committee of the China Petroleum and Chemical Industry Federation, told the Wisdom News Agency that the revision of the methanol gasoline M15 landmark in Shaanxi Province has passed the expert review and is pending the approval and release of the Quality Supervision Bureau, but there is still no timetable for the introduction of the methanol gasoline M15 national standard after seven years of revision.Chen Xianjie expressed that,
[Building Materials Network] In September, the price of methanol futures rebounded strongly, boosted by the improvement of supply and demand in the industry, and the main contract increased by about 150 yuan/ton.In the coming October, downstream formaldehyde, plate and other industries will still be in the traditional peak consumption season, which is expected to have a strong positive effect on methanol demand.At the same time, the macro-economy has stabilized and recovered, and the upstream anthracite market is expected to usher in a "counterattack"
[Building Materials Network] The pilot work of methanol fuel has been progressing steadily, but it is facing great environmental pressure, imperfect standard system and other difficulties.On August 22, 15 vehicles completely powered by methanol fuel appeared in Baoji, Shaanxi.This marks that Shaanxi Province has taken substantial steps since it was identified as a pilot methanol vehicle by the Ministry of Industry and Information Technology, and Shaanxi Province has become the second in China after Shanxi Province
