Clays are one of the important natural materials‚ which have been examined for catalytic applications. Clays are characterized by a layered structure and hence they are slippery when wet. They are broadly classified as cationic or smectite type (having layer lattice structure in which two-dimensional oxyanions are separated by layers of hydrated cations) and anionic or brucite type (in which the charge on the layer and the gallery ion is reversed complimentary to smectite type). Anionic clays are

The Fischer projections shown above are two possible stereoisomers that could form in the bromination reaction that you will perform. One is the result of a syn addition‚ the other is the result of an anti addition mode. Note that each would form as a racemic mixture‚ (+). You are to determine‚ based on the melting point of your product‚ which

Forgery is a normal aspect of the art world. This topic is about the skill involved in producing ’true’ forgeries within the world of art. It is stressed that the forger is to be seen as an artist‚ in that he or she must sometimes enter the mind of the original artist‚ master his or her techniques‚ and otherwise execute works that can withstand the expert eye. There are many ways that people will do in order to make a fast buck without thinking about the techniques that are done to detect forgery

Preparation of Bromotriphenylmethane Abstract The structure of a major component of star anise oil was derived by analyzing its IR spectroscopy melting point of after oxidation and purification. From the evidence obtained‚ it was concluded that the exact structured should be p-methoxybenzoic acid. Introduction The purpose of this experiment is to determine the structure of the major component of star anise oil. It is already known that this component has a molecular formula C10H12O. This

Du Pont uses only a small number of hazardous substances – such as lead‚ aniline‚ and orthotoluidine – that require special control. Over the years‚ the company has promulgated several policies dealing with reproductive hazards‚ particularly one that addressed the problem of fetal damage from chemical exposure.
