Introduction
Shanxi Sanwei Group Co., Ltd. has
established a set of *5,**0tons/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,*-Butanediol that
will have a creative impact and significance to the
development of chemical industry in China.
Product
Properties
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%.
Product Uses
PTMEG is an important raw material for
the production of polyurethane (such as PU fibers, polyurethane
elastomer, synthesized leathers, paint additives, adhesives and
sealants), polyesters and polyamides.

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
*0℃. Frozen PTMEG can be heated at about *0℃ for *4 hours to
melt. PTMEG should not be stored at *0℃ 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.
