Antifreeze concentrate is disclosed having water soluble liquid alcohol freezing point depressant and corrosion inhibitor comprising carboxylic acids or their salts and a triazole compound, wherein the concentrate contains: (1) C.sub.5 -C.sub.16 aliphatic monobasic acid or the alkali metal, ammonium or amine salt thereof; (2) hydrocarbyl triazole; and (3) imidazole.

Corrosion-inhibited antifreeze formulations having monocarboxylic,

A corrosion inhibitor for use in water and liquid alcohol antifreeze/coolant compositions comprising the combination of a C.sub.5 -C.sub.16 aliphatic monobasic acid or the alkali metal, ammonium, or amine salt of said acid, a C.sub.5 -C.sub.16 hydrocarbyl dibasic acid or the alkali metal, ammonium, or amine salt of said acid, and a hydrocarbyl triazole gives synergistic corrosion protection to metal surfaces as compared with formulations containing either the monoacid or diacid component alone, or formulations containing other conventional corrosion inhibitors.

Monobasic-dibasic acid/salt antifreeze corrosion inhibitor

Disclosed is a slow release fertilizer composition comprising a slack wax-urea adduct prepared by urea-dewaxing petroleum hydrocarbons in which the wax to urea ratio ranges from 0.08 to 0.30 and particularly intended for use on dry, desert-like soils. Solar radiation causes the wax to melt thereby slowly releasing the urea with the wax forming a biodegradable protective layer against wind erosion and water losses.
