Reaction Principle
a) CH2=CH-CN + CrVI ¨ HCN
b1) HCN + HgCl2 ¨ HCl
b2) HCl + methyl red ¨ red reaction product
Cross Sensitivity
Styrene up to 50 ppm does not influence the indication. Butadiene
reacts with the oxidation layer; in the presence of butadiene, the
acylonitrile indication will be too low (e.g. up to 50 % too low with
400 ppm butadiene).
