EXAMPLE 2

Preparation of Vanadyl Silicotungstate in iso-propanol

1.14 g of silicotungstic acid hydrate (Fluka) (0.359 mmoles) dissolved in 20 ml of iso-propanol (Aldrich) were placed in a 250 ml flask and subsequently, 116 g of vanadium(V) oxytriisopropoxide (Cas No. 5588-84-1) (Aldrich) (0.475 mmoles) dissolved in 60 ml of iso-propanol (Aldrich) were added: the mixture obtained was heated to 70° C., for 3 hours, obtaining a colorless solution. The solution obtained was cooled to ambient temperature (25° C.) and transferred into a glass vessel with a plug: one drop of said solution was placed on a strip of wet litmus paper to measure the pH, which was equal to about 6-7.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
