removing silicon‚ sulphur‚ manganese‚ phosphorus and carbon from pig iron by oxidation conducted at a temperature of about 1300oC. • Oxygen required for oxidation is supplied partly by the atmospheric air passing through the furnace and partly by the additions of iron oxide. • Silicon‚ manganese and phosphorus in molten pig iron form SiO2‚ MnO and P2O5. These oxides combine with iron oxide to form a low melting point liquid slag. • As the iron loses its silicon‚ manganese‚ phosphorus and carbon‚ the

Agro based industries Cotton Location -The first cotton textile mill on modern lines was started in Bombay in 1854. Later the mills were started at Ahmedabad in 1858‚ then in Kanpur‚ Nagpur‚ Sholapur‚ Surat and other places. As I said before‚ today India holds the third place among the cotton textile producing countries of the world. It provides emplyment to a large number of people and also helps to ear foreign exchange. Gujarat and Maharashtra states‚ lead the country in cotton textile production

naphthalene. Introduction In 1990‚ professor E.N. Jacobsen reported that chiral manganese complexes had the ability to catalyze the asymmetric epoxidation of unfunctionalized alkenes‚ providing enantiomeric excesses that regularly reaching 90% and sometimes exceeding 98% . The chiral manganese complex Jacobsen utilized was [(R‚R)-N‚N’-Bis(3‚5-di-tert-butylsalicylidene)-1‚2- cyclohexanediaminato-(2-)]-manganese (III) chloride (Jacobsen’s Catalyst). (R‚R) Jacobsen’s Catalyst Jacobsen’s catalyst
