How to remove residual propylene glycol methyl ether ester in iron oil drum

Both propylene glycol ether and ethylene glycol ether are ethylene glycol ether solvents, and the toxicity of propylene glycol ether to human body is lower than that of ethylene glycol ether products, so it belongs to low toxic ethers. Propylene glycol methyl ether has a weak ether smell, but it has no strong pungent smell, so it is more widely used and safer. Because its molecular structure contains both ether groups and hydroxyl groups, it has excellent solubility, suitable volatilization rate and reactivity, and has been widely used.

Usage 1: mainly used as solvent, dispersant and diluent, and also used as fuel antifreeze and extractant.

Application II 65438+ o-methoxy -2- propanol is the intermediate of herbicide metolachlor.

Usage 3: As solvent, dispersant or diluent, it is used in paint, ink, printing and dyeing, pesticide, cellulose, acrylate and other industries. It can also be used as fuel antifreeze, cleaning agent, extractant and non-ferrous metal concentrator. It can also be used as a raw material for organic synthesis.

Purpose Tetrapropylene glycol methyl ether (107-98-2) is mainly used as an excellent solvent for nitrocellulose, alkyd resin and maleic anhydride modified phenolic resin. Used as an additive for jet olefin antifreeze and brake fluid; Used as solvent for printing ink, textile dye and textile oil; Waterborne coatings made from it are widely used in automobile industry.

Uses Pentapropylene glycol methyl ether (107-98-2) is widely used in paints and detergents. It is specially used as an active solvent for waterborne coatings; Active solvents and coupling agents for solvent-based printing ink; Solvent for ballpoint pen and pen ink; Coupling agents and solvents for household and industrial cleaners, rust removers and hard surface cleaners; Solvents for agricultural pesticides; Mixed with propylene glycol n-butyl ether for glass cleaner formula.

Use 6 as solvent; Dispersants or diluents are used in coatings; Ink; Printing and dyeing; Pesticides; Cellulose; Acrylate and other industries. Can also be used as fuel antifreeze; Cleaning agent; Extractant; Nonferrous metal concentrator, etc. It can also be used as a raw material for organic synthesis.

Fire prevention measures of propylene glycol methyl ether;

Store in a low temperature, dry place with good air circulation, away from places where fires may occur. I prefer to store it outdoors or in a place that is not influenced by others, and separate it from things that are not suitable for storage. Containers should be connected and grounded to avoid electrostatic sparks. Smoking should be prohibited in places where the product is stored and used. Use tools and equipment that will not generate sparks. Empty barrels filled with the product can also be dangerous. As there are still residues (vapor, liquid) of this product in these containers, please check all warning signs posted on this product barrel.

Fire extinguishing medium: dry powder compound, foam or carbon dioxide. Putting out the fire with water may not work. Spraying water can cool the burning container, dilute the overflow and make it a non-combustible mixture, thus protecting the safety of those who prevent leakage and vapor diffusion.

Special fire information: Wear protective clothing in case of fire. Wear breathing assistance equipment with protective mask, which can work under specific pressure or other specific pressure modes.

Propylene glycol methyl ether is mainly used as an excellent solvent for nitrocellulose, alkyd resin and maleic anhydride modified phenolic resin, as an antifreeze for jet fuel and an additive for brake fluid. Mainly used as solvent, dispersant and diluent, and also used as fuel antifreeze and extractant.
