Lxxvii. the Chemistry of Amino-acid Deamination

THE final phase of amino-acid metabolism, involving the removal of nitrogen from the amino-group and the production of urea, is generally regarded as involving two distinct processes: (1) deamination, with the liberation of ammonia, (2) dehydration of ammonium carbonate, with formation of urea. The change being represented as: R. CH(NH2) . COOH NH3 (NH4C03CON2H4 Now, while there is no doubt as ...

Separation of sillimanite from beach sands contaminated with shell

Sillimanite is a very important raw material for the manufacture of refractory bricks used in iron and steel, cement and glass industries. In some coastal stretches of south India, the beach sand is contaminated with shell. After recovering heavy minerals like ilmenite, rutile, zircon and garnet by various physical separation techniques, the final sand containing sillimanite, quartz and shell i...
