Diethylene glycol Usage And Synthesis

Chemical   Properties

clear oily   liquid

General   Description

A colorless   liquid. Denser than water. Contact may slightly irritate skin, eyes and   mucous membranes. May be slightly toxic by ingestion. Used to make other   chemicals.

Air & Water   Reactions

Slightly soluble   in water.

Reactivity   Profile

Diethylene   glycol is incompatible with strong oxidizing agents. Diethylene glycol is   also incompatible with strong bases. Diethylene glycol can react with   sulfuric acid and other dehydrating agents, nitric acid, oxygen, hydrogen   peroxide, perchloric acid and strong acids. Mixtures with sodium hydroxide   decompose exothermically when heated to 446° F

Health Hazard

Ingestion of   large amounts may cause degeneration of kidney and liver and cause death.   Liquid may cause slight skin irritation.

Fire Hazard

Diethylene   glycol is combustible.

 

 

 

Application:

Diethylene glycol   is a important solvent, used for ink and paint industry.

 

 

Diethylene glycol is a high solvating Dibenzoate plasticizer. As a replacement for phthalate plasticizers recommended by the European Chemical Agency (ECHA),it has been used for many years in a wide variety of applications, including adhesives, PS sealants, resilient flooring, PVC, artificial leather cloth, PVC coated cloth, etc..

Product Advantages

1.Environmentally friendly plasticizers recommended by the European Chemical Agency (ECHA).

2.Does not contain any phthalates and can be used as a main plasticizer.

3.High solvating.

4.Low fusing point.

5. Compared with DOP, its required processing temperature is lower so that the processing speed is faster.

6.Products containing Diethylene glycol  exhibit excellent stain and extraction resistance. 7.Soft under low temperature.

8. Impervious to light and heat.

9.Compatible with polyvinyl acetate emulsions and copolymer emulsions.

10.Very good plasticizing effect in water-borne adhesives.

11.Low VOC content.

Diethylene glycol Function:

1. Mainly used as solvent, such as the solvent of nitrocellulose, rubber, resin, grease, paint, medicine, etc. Also can be used as resin plasticizer, tobacco anti-drying agent, fiber lubriant and gas desiccant, etc.

2. Mainly used for gas dehydrant and aromatics extraction solvent. Also used for cellulose nitrate, resin, such as grease, printing ink solvent, textile softener, finishing agent, and coumaric ketone and indene extracted from coal tar, etc.

3.Used for the preparation of plasticizer, also used as extracting agent, desiccant, heat preservation agent, softening agent and solvent, etc

A shrinkage of diethylene glycol is mainly used for natural gas dehydration and aromatics extraction, used as a solvent, ink adhesion and textile dyes are also used in rubber and resin plasticizers, polyester resin, fiberglass, urethane foam, the production of lubricating oil viscosity improver, and other products.

4.Used as gas dehydrant and aromatics extraction solvent, and also used as a textile lubricant, and finishing agent, softener and plasticizer, humidifying agent, sizing agent, nitro cellulose fiber, resin and grease solvent.

5.Used as a solvent, gas dehydrant, extraction solvent, water softener, liquid and gas chromatography is suitable for aqueous solution analysis, selective polyethylene glycol, used to analyze the content of oxygen compounds (especially alcohol),aniline, fatty amine, pyridine and quinoline.
