Synthesis and Antinematodal Activity of 3-<i>n</i>-Alkylphenols
Several 3-alkylphenols including 3-undecylphenol, which was isolated from a Sumatran rainforest plant, were synthesized to investigate their antinematodal activity against the phytopathogenic nematodes, Bursapherencus xylophilus. A three-step synthesis involving the treatment of 2-cyclohexen-1-one with the Grignard reagent, oxidation of the resulting 1-alkyl-2-cyclohexen-1-ol and subsequent aromatization of 3-alkyl-2-cyclohexen-1-one successfully afforded such phenols. Among the 3-alkylphenols, 3-nonylphenol showed the highest activity, while 3-decylphenol and 3-undecylphenol also showed high activity.

Additives for lubricating oils, especially automatic transmission fluids, are disclosed comprising a heterocyclic compound containing boron and of the formula
wherein R is inorganic or organic and R₁ and R₂ are the same or different organic radicals, in admixture with or as the reaction product of reaction with an ester of a polyhydric alcohol. The boron-containing heterocyclic compound may contain sulfur. It may comprise the product of reacting together ammonia or a primary amine, an aliphatic or aromatic epoxide and a boric acid in a ratio of 1: 2: 1. Lubricating oils and transmission fluids containing these additives are also disclosed.

The invention describes a composition for use in disinfecting a surface for personal use, such as a public restroom facility or telephone. The composition and delivery of the composition provides for the placement of a thin layer of disinfectant which includes a acid-base indicator. The acid-base indicator disappears as the thin layer effects the germicidal activity of the disinfectant. The composition is also rapidly drying, so that the acid-base indicator disappears as well as the disinfecting composition leaving the surface dry. The invention also relates to use of the compositions in a lotion, such as a sunscreen. Use of the acid-base indicator provides a method to visualize where the lotion is applied by color, with the color then later dissipating.
