Methylene chloride or dichloromethane with CH2Cl2 as its chemical formula is a volatile, colorless liquid with an odor of chloroform. It is utilized in a wide variety range of industrial procedures, like paint uncovering, pharmaceutical processes industry, paint removers industry, and also in cleaning surface of metal products.
In the Occupational Safety and Health Report (OSHA), this chemical like Benzene is considered a potential occupational carcinogen. This means that exposure to this substance for a prolonged period of time may pose a serious risk to humans.
Where is it used?
It is an extremely evaporative solvent and is widely applied in paint uncovering, glue, and adhesives, remove additional grease from metal surfaces, urethane foam manufacturing, print development, aerosol materials, and as a process solvent in the chemical and pharmaceutical industries and manufacturers.
Chemical and Physical properties
in the table below some of the chemical and physical properties of this product are mentioned. all data that is mentioned in this table is gathered from the Wikipedia website:
Industrial packing of Dichloromethane
packing of chemicals is one of the most important factors in the transportation segment. below, there are some of the Shanghai Chemex group projects for methylene chloride in China. the common packing for this chemical is metal drums as you can see below:
DCM manufacturing process
DCM is produced by the reaction of chloromethane or methane with chlorine gas at temperatures of 500-500 ° C. At this temperature, methane and chloromethane undergo the following reactions to produce more chlorine products. The reactions are as follows:
1) CH4 + Cl2 → CH3Cl + HCl
2)CH3Cl + Cl2 → CH2Cl2 + HCl
3)CH2Cl2 + Cl2 → CHCl3 + HCl
4)CHCl3 + Cl2 → CCl4 + HCl
In the production process, a mixture of chloromethane, dichloromethane, chloroform, and carbon tetrachloride is obtained, each of which is used separately to obtain distillation.
Market outline of DCM
The Global Market of this product is evaluated to reach $1,078 Million by 2024; growing at a CAGR of 5.2% from 2016 to 2024. Developing economies such as Malaysia and South Korea are observing increasing requests due to growth in the expenditure of adhesives and developing textile and packaging parts. The worldwide marketplace of this component is driven by elements like increasing requests from the paints industry, raising the growth of new applications over diverse verticals, and enhancing speculations in R&D on developing brand new operations. Nevertheless, risks related to methylene chloride could cause a main impediment for market development. In addition, rising applications, and market enlargement would supply growth occasions in upcoming years.
Methylene Chloride Applications
There are several important industrial applications of dichloromethane that is mentioned below:
Dichloromethane is a colorless solvent used in paint and varnish cleaners. It is also used in the bathtub refinishing.
One of the most industrial applications of this component is in the production of paint removers, pharmaceuticals, and solvents which are used industrially through the process. There are other applications for Methylene chloride which are mentioned below:
Food and Beverage industrial production
One of these material applications is as an extraction factor in the food and beverage manufacturing industry. For instance, it can be used to eliminate caffeine from unroasted coffee beans and tea leaves, to make produce tea and coffee without caffeine
Dichloromethane can be used to remove grease and fat from metal surfaces and other parts, like airplane segments and other metal equipment. Industrial Lubricants and degreasing products that are used in the automotive industry could include methylene chloride. Automotive industry experts utilize a vapor of this material degreasing procedure to eliminate oils and grease from diverse parts of the car. This process enables safe cleanings of types of equipment.
In Pharmaceutical laboratories, dichloromethane is applied to extract chemicals from plants or foods, or seeds. Without any harm to metal equipment in laboratories, it can clean tools safely.
How can people be exposed to dichloromethane?
The U.S. Environmental Protection Agency (EPA) reported final laws which are forbidding the usage of methylene chloride in all paint strippers. Being exposed to this component is predominately from breathing in its vapor and mist, but this material can also penetrate into the body through skin contact and by devouring.
What are the health effects of DCM?
Contact of this material to the skin and eyes can affect annoyance. It causes lung and liver cancers in mice experiments. Although data in humans are still indecisive.
How can the taskmaster make the workplace safer for workers?
These tasks can put them in less exposure of this material for Employees who work with dichloromethane tanks:
- Elevating the tank height
- Using tanks of different sizes and shapes due to workers physical condition
- Enhancing the depth of solvent in the tank
- Downgrading manual work in and above tanks
- Wearing full personal protective equipment
