The properties and uses
of diethylene glycol monobutyl ether
1. properties

diethylene glycol monobutyl ether, also known as diethylene glycol monobutyl ether, is a colorless and transparent liquid with a faint special smell. Its molecular formula is C8H18O3 and its molecular weight is 162.23. Diethylene glycol monobutyl ether has low toxicity and is less irritating to the skin. It has a boiling point of 247°C, a flash point of 121°C, a density of 1.01g/cm³, a viscosity of 6.5mPa · s, a surface tension of 30.9mN/m, and a refractive index of 1.4246. In addition, diethylene glycol monobutyl ether has good miscibility and can be miscible with water, alcohols, ketones, esters and other solvents.

2. use

of diethylene glycol monobutyl ether in the field of chemical production of raw materials has a wide range of uses, mainly used in the following aspects:

1. cleaning agent: diethylene glycol monobutyl ether has good cleaning performance, can be used as metal cleaning agent, glass cleaning agent. Because of its low toxicity and low skin irritation, it is widely used in the field of industrial cleaning.
2. Solvent: diethylene glycol monobutyl ether can be used as a solvent for coatings, inks, resins, etc., to improve the fluidity and drying of products.
3. Chemical reaction media: diethylene glycol monobutyl ether can be used as a medium for some chemical reactions to promote the reaction.
4. defoaming agent: diethylene glycol monobutyl ether has defoaming effect and can be used as defoaming agent in coatings, emulsions and other systems.

In short, as an important chemical raw material, diethylene glycol monobutyl ether has been widely used in the fields of cleaning agent, solvent, chemical reaction medium and defoamer.

When using diethylene glycol monobutyl ether, it is necessary to maintain a good ventilation environment and avoid contact with open flames and high temperature surfaces to avoid fire or explosion. In addition, avoid contact with oxidants, acids and other substances to avoid chemical reactions. During use, protective gloves and glasses should be worn to avoid contact with skin and eyes. In case of contact with skin or eyes, rinse immediately with water and consult a professional doctor for advice.

In conclusion, as an important chemical raw material, diethylene glycol monobutyl ether has broad application prospects. During use, it is necessary to pay attention to safety matters and abide by relevant operating procedures to ensure the smooth progress of the production process.
