This form of the acid is stable indefinitely and is commercially available. Such solutions are hygroscopic. Thus, if left open to the air, concentrated perchloric acid dilutes itself by absorbing water from the air. Dehydration of perchloric acid gives the anhydride dichlorine heptoxide: [10] 2 HClO 4 + P 4 O 10 → Cl 2 O 7 + H 2 P 4 O 11

n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
Any material which exhibits a mean pressure rise time less than or equal to the pressure rise time of a 1:1 nitric acid (65 percent)/cellulose mixture and the criteria for Packing Group I and II are not met. Group II 5.2: All All Division 5.2 materials do not have a packing group in Column 5 of the 49 CFR 172.101 Table.
Ammonium perchlorate (AP) is produced by reaction between ammonia and perchloric acid.This process is the main outlet for the industrial production of perchloric acid.The salt also can be produced by salt metathesis reaction of ammonium salts with sodium perchlorate.

Perchlorate salts are typically manufactured through the process of electrolysis, which involves oxidizing aqueous solutions of corresponding chlorates.This technique is commonly employed in the production of sodium perchlorate, which finds widespread use as a key ingredient in rocket fuel. [5]
It can be obtained by reacting gadolinium(III) oxide and perchloric acid (70~72%) at 80 °C. [1] It can form colorless Gd(ClO 4 ) 3 ·9H 2 O·4C 4 H 8 O 2 complex crystals with 1,4-dioxane . [ 2 ] It reacts with inositol , sodium acetate , and sodium hydroxide to obtain complexes containing giant molecular clusters {Gd 140 }. [ 1 ]
