Secondary butyl alcohol does not containdetectable quantities of polycyclic aromatics, heavy metals or chlorinatedcompounds.Secondary butyl alcohol is a solvent for ester gum, many natural resins andvegetable oils; in the presence of aromatic hydrocarbons it forms a goodsolvent mixture for alkyd coatings and lacquers based on ethyl cellulose. As alatent solvent in nitrocellulose lacquers, it provides good gloss and levellingproperties. The mutual solvency of secondary butyl alcohol for water and oilhas made it useful as a coupling agent in the formulation and preparation ofindustrial cleaning compounds, oil treating chemicals, paint removers andoil-water emulsion breakers.Sec-butyl alcohol also acts as a chemicalintermediate in the manufacture of methyl ethyl ketone, ore flotation agents, fruitessences, perfumes, dye-stuffs and wetting agents. Other uses for sec-butylalcohol are as a solvent in the manufacture of polypropylene, for specialgreases, in printing inks and in adhesives for plywood laminates.Provided proper storage and handling precautions are taken we would expectsecondary butyl alcohol to be stable for at least 12 months.Advice on storageand handling may be obtained from your local Shell Chemicals company.Secondary butyl alcohol is flammable. Its vapour can readily form an explosivemixture in air. It is harmful by inhalation. For advice please refer to SafetyData Sheet, which can be found on www.shell.com/chemicals.
