What is cuso4.5h20

Moreover, this compound exothermally dissolves in water. Then, it forms an aqua complex containing one CuSO4 molecule in association with six water molecules, and this complex has an octahedral molecular geometry. The molar mass of it is That mean; the compound decomposes before melting. Furthermore, copper sulfate is anhydrous whereas copper sulfate pentahydrate is a hydrated form.

With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry.

This method works well with a However 2-butyl acetate was obtained in high yield when 2-buthanol was used independently in the same reaction conditions. It means although sec-alcohols can be acetylated with this method, in the presence of primary hydroxyl group, the chemoselective reaction takes place and only primary hydroxyl group can be selectivity acetylated.

In conclusion we have developed a catalytic and solventless system for acetylation of alcohols and phenols using available, inexpensive and extremely safe reagent such as copper ll sulfate for the mild and high yielding acetylation of alcohols and phenols. The salient features of these reactions are, use of Neither use of solvent nor elevation of reaction temperature makes operations more convenient.

The catalyst can be recycled at least five times without significant lose of catalytic activity. We believe copper ll sulfate is the greenest catalyst which has ever been used for acetylation of alcohols and phenols and this heterogeneous catalytic and solventless acetylation will find many applications in organic synthesis and industry.

All products were known and their physical and spectroscopic data were compared with those of authentic samples. IR spectra were recorded on Brucker cm All chemicals were purchased from commercial suppliers and were used as received. Acetylation of alcohols and phenols catalyzed by copper ll sulfate.

Typical procedure. Benzyl alcohol 5 mmol, 0. The mixture was stirred at room temperature for 24 hours Table 1. Combined organic layers were dried over Na 2 SO 4 , filtered and evaporated to dryness to afford the acetylated products in high yields. Green, T. Larock, R. Miyashita, M. It is percent minus 40 mesh. Copper Sulfate Pentahydrate can be used to destroy algae in water supplies. It controls tadpole shrimp in flooded rice fields and is used as a sewer treatment to destroy roots.

Copper Sulfate can be used as an ingredient in Bordeaux Mixture sprays as a fungicide to control plant diseases. It is an ingredient in wood treating chemicals to protect against mildew and rotting.
