B&A SULFAMIDE Recently, one of our ads went on a " f i s h i n g e x p e d i t i o n " to e x p l o r e possible uses for a number of new chemicals. Among them was B&A Sulfamide. So m u c h i n t e r e s t w a s expressed in Sulfamide t h a t we are taking this opportunity to tell you more about it. B&A Sulfamide is similar to urea in many of its reactions, except that it is more acidic, and can act as a di basic acid. Here are twelve properties and reactions of this interesting new chemical. Do they give you some ideas of your own?
Nitration NH 2 S0 2 NH 2 + HNO3-
NH 2 S0 2 NHN0 2 + H 2 0
Chlorination NH 2 S0 2 NH 2 + HOCI-
NH 2 S0 2 NHCI + H 2 0
Salt Formation NH 2 S0 2 NH 2 + 2Na0H9~ NaNHS0 2 NHNa + 2H 2 0 Various mono- and di-metallic salts have been made.
Heat NH 2 S0 2 NH 2 -
NH 2 (S0 2 NH) x S0 2 NH 2 + (S0 2 NH) 3 + NH 3
Hydrolysis H20 NH 2 S0 2 NH 2 + H 2 0*- NH2S03NH4 » (NH 4 ) 2 S0 4 Sulfamide is stable in dilute acid or alkaline solution.
PCI, NH 2 S0 2 NH 2 + 2PCI 5 -
S02(N:PCl3)2 + 4HCI
Alcohols NH 2 S0 2 NH 2 + 2R0HR20 + NH2S03NH4 Sulfamide is a strong dehydrating agent under some Organic Acids NH 2 S0 2 NH 2 + RCOOH
