Adipic acid is
commonly known as “fat acid” with the formula C6H10O4, molecular weight is 146.14, which is an
importantdibasic acidin aliphaticsdibasic acid.
It is a kind of white crystalline solid, and odorless. It has common features
with aliphaticsdibasic acid, including salt forming reaction, esterification
reaction, amidation, etc. Meanwhile, it can form polymer with diamine through
polycondensation reaction.
Adipic acid is
mainly used in producing nylon fiber and engineering plastics, and polyurethane
in quantity. Most of parts are used to produce PU, liquid for sole,
polyurethane foam, etc. A small number of them are used for high quality
lubricating oil.
High quality ester
of adipic acid can be used as PVC and its copolymer, plasticizer of natural
synthetic rubber. A large number of adipic acid ester is used to produce food
packaging, thin film and PVC for insulation.
Adipic acid is
also used for sour agent of food and drink. It is not easy to deliquesce, so it
is used in dry food, and can be kept in a long time.
The Adipic acid
products adopt cyclohexene method to make cyclohexanol, then nitric acid
oxidation. The products have obvious advantages, such as high purity, good
quality, and large output. The production technology has obvious advantages of
low raw material consumption, low energy consumption, low three wastes
discharge, high automaticity, safety and environmental protection.
We have: pure
adipic acid, cyclohexane, cyclohexanol,diacid, cyclohexene, dilute nitric
acid(65%), etc.
Packaging: pure
adipic acid adopts PP complex bags (PE coating inside), the size is 1000kg/bag,
500kg/bag.
Safety, storage
and transportation: adipic acid is stable, non-toxic, and not easy to
deliquesce. Be careful of water-proof, rain-proof when transportation. When the
content is higher than 14%, it is easy to have static to cause fire, so please
use carefully. The upper explosive limit of adipic acid dust mixed with air
blending is 7.9%, the lower limit is 3.94%.
