More Amino Nitrogen per Pound Because of their low equivalent weight, Methylamines offer more amino nitrogen per pound than other comparable aliphatic amines. Low cost and high nitrogen content make Rohm & H a a s methy la mines ideal raw materials for producing rubber accele rators, herbicides, photographic developers, dyestuffs, pharma ceuticals, quaternary ammonium salts a n d surface-active agents. W h e n using Rohm & Haas methy la mines, you get (1) high quality made possible by 20 years of production experience, (2) an always-dependable supply from 2 plants at separate locations, (3) technical service on handling these amines. R o h m & H a a s monomethylamine, dimethylamine and trimethylamine are available in aqueous or anhydrous form—in tankcars, cylinders or drums. If you write to Dept. SP, we will be glad to supply complete technical literature.
