In the chemical industry, Dichloromethane (CAS#75 - 09 - 2) is a crucial organic compound. This colorless, volatile liquid with a moderately sweet aroma plays a significant role in various industrial applications. Let's take a closer look at the latest market trends, along with some in - depth knowledge about this compound. Our recent market research reveals interesting trends in the Dichloromethane market. From 1st to 5th January 2025, the price of Dichloromethane in East China has increased, ranking among the top in terms of weekly average price increase. Currently, the mainstream transaction price of Dichloromethane in the Jiangsu - Zhejiang market is 2800 - 2950 yuan/ton, and in the Shandong market, it is 2780 - 2820 yuan/ton.
Regarding the supply side, it remains relatively stable. Some enterprises have made minor adjustments to their production capacity, but the overall supply is consistent. For example, Guangxi Tiandong Jinyi Technology Co., Ltd. operates a 370,000 - ton/year methane chloride unit at 90% load, and the ex - factory price of Dichloromethane is 3350 yuan/ton. Jiangxi Liwen's 160,000 - ton/year unit is operating normally, with an ex - factory price of 3050 yuan/ton. Zhejiang Quhua's 400,000 - ton/year methane chloride unit is also running smoothly, with an ex - factory price of 3050 yuan/ton. Dichloromethane, with the chemical formula CH₂Cl₂, is a member of the chlorinated hydrocarbon family. It has a molar mass of approximately 84.93 g/mol. One of its most notable physical properties is its relatively low boiling point of around 39.6 °C. This low boiling point makes it highly volatile at room temperature, which is beneficial in many industrial processes where rapid evaporation is required. It has a density of 1.3266 g/cm³ (20°C), which is higher than that of water. This means that when Dichloromethane is mixed with water, it will sink to the bottom, facilitating separation processes in some applications.
Chemically, Dichloromethane is relatively stable under normal conditions. However, it can react under specific circumstances. When exposed to high temperatures, strong oxidizing agents, or ultraviolet light, it may decompose. Decomposition can lead to the release of harmful substances such as hydrogen chloride and phosgene, a highly toxic gas. This is why proper handling and storage of Dichloromethane are of utmost importance.
There are several methods for producing Dichloromethane. The most common one is the methane chlorination process. In this process, methane (CH₄) reacts with chlorine (Cl₂) in the presence of light or heat. The reaction is a step - by - step substitution reaction. First, methane reacts with chlorine to form chloromethane (CH₃Cl). Then, chloromethane can further react with chlorine to produce Dichloromethane. The reaction can be represented as follows:
CH₄ + Cl₂ → CH₃Cl + HCl
CH₃Cl + Cl₂ → CH₂Cl₂ + HCl
Another method involves the reaction of methanol with hydrogen chloride and oxygen over a catalyst. This method offers advantages such as better control over the product selectivity and potentially more environmentally friendly operation compared to the traditional methane chlorination process.
Dichloromethane has a wide range of applications across multiple industries. In the pharmaceutical industry, it serves as an excellent solvent for drug extraction and purification. Many pharmaceutical compounds are soluble in Dichloromethane, allowing for the separation and isolation of active ingredients from complex mixtures.
In the adhesives and glues industry, Dichloromethane is used to dissolve polymers. By dissolving polymers, it enables the creation of a homogeneous adhesive mixture that can be easily applied to surfaces. When the Dichloromethane evaporates, the polymers solidify, forming a strong bond between the adhered materials.
As a paint stripper, Dichloromethane is highly effective. Its solvent properties allow it to break down the chemical bonds in paint, making it easier to remove paint from various surfaces such as metals, wood, and plastics.
In the production of polyurethane foams, Dichloromethane is used as a blowing agent. During the polyurethane formation reaction, Dichloromethane vaporizes due to the heat generated by the reaction. The vapor forms bubbles, which expand the foam and give it its characteristic porous structure.
However, the use of Dichloromethane is facing increasing regulatory scrutiny. The US Environmental Protection Agency has proposed a ban on most uses of Dichloromethane, prohibiting all consumer uses and most industrial and commercial uses within a certain period. This is mainly due to its potential health and environmental impacts. Dichloromethane is classified as a possible human carcinogen, and its release into the environment can contribute to air pollution and ozone depletion.
