Natural gas is one of the major sources of fuel and raw material to industries all over the world. However, it contains some acid gases such as C O2 and H2 S which are corrosive and harmful to the environment. These acid gases must be brought to permissible limits to promote safety in the operation and increase the heating value of the natural... Continue Reading

ABSTRACT The present paper describes the synthesis of Acid Orange(7)dye which can be used as dyes for cellulose acetate biopolymer. They were obtained by the diazotization of a monoazo component of the mono-azobenzene type, followed by coupling. The monoazo components were obtained by the diazotization of sulphanilic acid and coupling with... Continue Reading
