Miscible with water.
Use
as a solvent, dispersant or diluent used in coating, ink, printing and dyeing, pesticide, cellulose, acrylate and other industries. It can also be used as a fuel antifreeze, a cleaning agent, an extractant, a non-ferrous metal ore dressing agent, etc. It can also be used as a raw material for organic synthesis.
Safety
- mouse oral LD50 6.6g/kg. Vapor on the eyes and nasal mucosa of animals have a stimulating effect, saturated concentration (18. 4~36.8 mg/L), a few hours of death. Liquid contact with the skin (rabbits) can cause anesthesia, long-term or large dose (> 10 ml/kg) contact, can be fatal (LD50 13~14g/kg). Protective gear should be worn during operation. In addition, the vapor generated should be removed in situ to protect the skin.
- This product is a flammable liquid and should be handled as a flammable liquid. Storage tanks and reactors, etc., should be covered with dry nitrogen. Electrical equipment should be explosion-proof. Flammable materials shall be stored and transported according to regulations.
Introduction
Nature:
1. Propylene glycol monomethyl ether is a colorless transparent liquid with low volatility and toxicity.
2. It is miscible with water and various organic solvents, and has good solubility.
Usage:
1. Propylene glycol monomethyl ether is mainly used as a solvent in organic synthesis and can be used to synthesize aliphatic polyethers, resins, and other chemicals.
2. It is also used in the preparation of coatings, inks, cleaning agents, camphor and other products, and has applications in industry such as cleaning agents, degreasers, and refrigerants.
Method:
Propylene glycol monomethyl ether can be synthesized by reacting propylene glycol and methanol under acidic catalysts. The specific steps include adding propylene glycol and methanol to the reactor, adding an appropriate amount of acidic catalyst, heating and stirring the reaction for a certain period of time, and distilling to obtain propylene glycol monomethyl ether product.
Security information:
1. Propylene glycol monomethyl ether has no significant harm to the human body under normal conditions, but long-term exposure may cause irritation to the respiratory tract, skin, and eyes.
2. When using, be careful to avoid contact with skin and eyes, and avoid inhaling vapors.
3. During storage and operation, attention should be paid to preventing fires and static electricity, and to avoid mixing incompatible substances.
4. It is necessary to use in a well ventilated area and wear appropriate protective equipment.
