They are designed with meta-xylene
diamine polyamide (MX nylon) suitable for reusable instruments or components.
Mitsubishi's MX-Nylon is a meta-xylene
diamine polyamide that, according to Foster officials, offers "excellent mechanical and barrier properties for molded components and devices, and medical packaging applications.
Furthermore, the aromatics plant will also produce mixed xylenes like toluene, orthoxylene and meta-xylene
from the integrated BTX units, as well as cumene, glycols, phenol, export LPG and light naphtha.
ClickPress, Mon Feb 16 2015] Meta-xylene
is an aromatic isomer of xylene with two methyl groups attached at the meta position of benzene.
For aviation blending, maximum meta-xylene
, paraxylene to a freeze point limit and minimum orthoxylene makes the most beneficial impact on the octane blend.
MXDA has been manufactured by ammoxidation of pure meta-xylene
into isophthalonitrile, followed by hydrogenation of the nitrile in the presence of ammonia using a nickel catalyst or other metallic catalyst under high temperature and pressures.
The complex uses the Cyclar process and produces 350,000 t/y of benzene, about 300,000 t/y of paraxylene, 45,000 t/y of orthoxylene and about 35,000 t/y of meta-xylene
In this case, a file containing the spectra of ozone, benzene, toluene, 2-butanone (MEK), and ortho-, para-, and meta-xylene
was first created by metering known concentrations of each compound in a stream of air flowing through the instrument's absorption cell.
