4 reactive organic chemicals immediately available for commercial use f-BUTYLAMINE

5 SULFOSALICYLIC ACID

3,4-DICHLOROANILINE & DODECYLANILINE

A low-viscosity, oil-soluble liquid, ί-butylamine cleanly undergoes reaction to give high yields of Schiff bases, quarternary and ordinary salts, cyanamides, acetonitriles, propionitriles and others.

Trifunctional 5-sulfosalicylic acid is a new and highly reactive Monsanto inter­ mediate now commercially available for your evalu­ ation. A tan crystalline material, this strong aro­ matic acid has a neutral­ ization equivalent of 107114. It gives you three re­ action sites for creative synthesis.

These highly reactive compounds convert readily with good yields by reactions of the amino group. They provide direct routes to unique isocyanates, sulfenamides, ureas, Schiff bases, anilides, aromatic ethanolamines and similar products.

The branched chain of M)utylamine acts as a "re­ action-regulator"—aids in controlling specific replace­ ment either of one or of both amino hydrogens. Monosubstitution takes place easily. Under mild re­ action conditions, with one mole of ethylene oxide, only traces of the di-hydroxyethylated amine are pro­ duced. Many /-butylamine deriva­ tives (aldimines, carbodiimides) possess unusually high stability compared with common primary amine derivatives.

Working samples to tankcar quantities of these four compounds are available now. Simply send your request on your company letterhead.

Because of the apparent hydrogen bonding potential of its reactive groups, 5-sul­ fosalicylic acid offers prom­ ise as a chelating agent for metals. It is already at work as an analytical reagent for use in the determination of various metals and to detect various types of proteins.

Examples:

With acylating agents

With sulfonyl chlorides

With acrylonitrile
