⊙ Methacrylic
acid |
1、Chemical
Name: methacrylic acid
2、Molecular formula:
3、Structural Formula:
4、Properties: It is a kind of
colorless transparent liquid in normal temperature,
with a penetrating odor; in a temperature under 16C
it becomes white acicular crystal, and performs as a
common organic acid, caustic, tending to change into
white amorphous substance when meeting with light and
heat; polymerization retardor is needed in storage.
5、Application: It is mostly used
in the making of paint thermohardening lacquer, adhesives,
cross linkers, textile, as well as printing and dyeing,
leather assistants; besides, as an organic unsaturated
acid, it is widely used in organic synthesis.

7、Production Capacity: 500t/year
8、Packaging: 10kg, 20kg, 180kg net
Wt, in plastic barrels or lining plastic iron drums。
9、Storage and Prevention:
Storage and Prevention: store in shady places, in
the temperature below 25 degrees centigrade, away from light,
heat and water. The storage life is three months. It is
changed into acicular crystal below 16 degrees centigrade,
and should be water-bathed with a gradual heating-up till
its dissolution. The polymerization retardor is paraphenetidine,
which dissolves in 60 degrees centigrade and do not disturb
the reaction. (Notice: if there are little flocculent things
due to the long storage time or others, it can be used as
normal after filtering.
