The heteropolymolybdates comprise a unique family of giant mole
cules. Perhaps you can put them to work. To help you evaluate them,
Climax has edited the vast and sometimes conflicting literature
on these compounds into a new technical bulletin, "Properties o f
Heteropolymolybdates". It is a concise presentation that will serve
as a guide to existing and potential industrial applications of these
unusual chemicals.
For samples and a copy of "Properties of Heteropolymolybdates"^

New York 36, Ν. Υ.
These heteropolymolybdates are now available
in laboratory quantities

S O M E PROPERTIES OF HETEROPOLYMOLYBDATES
EXTRAORDINARY SOLUBILITY Free acids are soluble in water up to 85% by weight of solution and are also soluble in alcohol and ether. Most metal, salts {including those of heavy metals) are also very soluble in water.
REACTIONS WITH ORGANIC BASES Heteropolymolybdates precipitate alkaloids, proteins, basic dyestuffs and many other organic bases.They are strongly adsorbed by nitrogen fibers, such as nylon and wool.
OXIDATION AND REDUCTION Heteropolymolybdates are powerful oxidizing agents. Reduced compounds w i t h 1,2 or 3 oxygen atoms removed are very strong reducing agents.
HYDRATION Heteropolymolybdates are highly hydrated. Most compounds have several stages of hydration, and can be converted revers!bîy from one stage to another.
