Superiority:

Shanxi Sanwei Group Co., Ltd. has established a set of 45,000tons/year Polytetramethylene Ether Glycol (PTMEG) plant using international advanced technology and equipment in China. State Council approves this PTMEG project despite the contribution to national debt as it helps to close the technological gap for this process in China and enables Sanwei spearhead the product chain based on 1,4-Butanediol that will have a creative impact and significance to the development of chemical industry in China.

Details:

 PTMEG is a white waxy solid. It turns into transparent liquid when the temperature is higher than room temperature. It dissolves easily in alcohols, esters, ketones, aromatic hydrocarbons and hydrocarbon chlorides. However, it does not dissolve in water or fatty hydrocarbons. When its molecular weight increases, its solubility drops. At room temperature, PTMEG is a good absorbent of water despending on its molecular weight and maximum up to 2%.

   Storage and Transportation
    PTMEG should be stored in totally closed containers sealed with dry nitrogen. The containers must be fitted with heating equipment outside or inside to keep their internal temperature at about 50℃. Frozen PTMEG can be heated at about 70℃ for 24 hours to melt. PTMEG should not be stored at 90℃ for a long time.
      In addition, it should be stored in cool, dry and well-ventilated places, and keep away from fire sources, sparks and naked flames. Due to PTMEG water absorbent and ease of oxidization, it should not be exposed to moisture or air. To avoid static electricity, its containers should be earthen during transportation.
      PTMEG becomes highly combustible at high temperature. If fire is started, one could use spray water, alcohol foam, dry chemicals products or carbon dioxide fire extinguishers to put off the fire. When loading or unloading it, one should wear gloves and safety glasses to prevent contacting with the eyes or skin.
