A process for making ortho alkoxy bisphenol monomers includes contacting an (alk-1-enyl)alkoxyphenol (type 1) with an alkoxyphenol (type 2) in the presence of an acidic catalyst. Both type of renewable phenols (type 1 and 2) can be generated from lignocellulosic biomass. The use of such alkoxy phenols as a precursor to bisphenol monomers has the potential to reduce the cost and environmental impact of structural materials, while meeting or exceeding the performance of current petroleum-derived polymers, such as thermoplastics and thermoset resins.

Disclosed is a process for preparing an aryloxyalkylene amine compound via an aminoethylation reaction comprising: a) reacting an aromatic hydroxyl compound in the presence of a basic catalyst with a 2-oxazolidinone compound of the formula II to form an intermediate reaction product;
wherein R
3
is selected from the group consisting of hydrogen or lower alkyl having 1 to 6 carbon atoms, R
4
is selected from the group consisting of hydrogen, straight or branched chain alkyl having from one to six carbon atoms, phenyl, alkaryl, or arylalkyl; and b) reacting the intermediate product of step a) with a polyalkylene polyamine.

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.
