Abstract

One of the first applications is suggested for the production of Sulphamic Acid (NH2SO2OH). It is known as Sulphuric Acid which is packed in paper bags. The present technique of producing Sulphamic Acid is by reacting oleum with Urea. The process is very cumbersome and hazardous. The current process for manufacturing Sulphamic Acid employed by most of the producers requires the disposal of a large quantity of dilute Sulphuric Acid. The process to manufacture Sulphamic Acid was developed by the author in early sixties and it has gone under certain modifications in order to improve the economics, but it is still hazardous and requires disposal of waste acid. This is described in detail to highlight need for innovation.
