PRIMENE 81-R Low viscosity, low cost, unusual reactivity make this high-molecular-weight amine valuable for many uses Here are some reasons why PRIMENE® 81-R, a high-molecu lar-weight, t-alkyl amine, should prove interesting to you: Low Viscosity
In the graph below, note that the highly-branched structure of PRIMENE 81-R provides fluidity at low temperatures, while a straight-chain amine of corre sponding molecular weight solid ifies at 75°F. Low Price
Tankcar price of PRIMENE 81-R is $0.28 per pound, f.o.b. Hous ton, Texas. Excellent Solubility in Petroleum Hydrocarbons
Solutions are clear even at high concentrations of PRIMENE 81-R.
Color Stability
The good color stability of* PRIMENE 81-R is attributed to this amine's unusual resistance - ^ to oxidation. Chemical Reactivity
- •
All reactions common to primary amines apply to PRIMENE 8lll$. In addition, the bulky t-alfc^l group often makes steric contirol possible. Typical syntheses ar^: (1) hydroxyalkylation to yield aminoalcohols, (2) cyanoethy|ation followed by reductive &£drogenation to give diamines/ (3) reaction with formaldehyde|fo give stable aldimines (straigintchain amines give unstable aldimines). \
Possible Uses
Application possibilities include: anti-dusting and anti-caking agent for hygroscopic products; stabilizer and sludge inhibitor in fuel oil; flotation agent; mold-release agent for rubber; intermediate for making sur factants, corrosion inhibitors, pharmaceuticals, rubber chem icals, insecticides, bactericides, dyes, antistatic agents, textile chemicals, latent catalysts for epoxy resins, oil-soluble salts of insoluble acidic materials.
