Abstract
Tetrahydrofurfuryl alcohol is substantially freed from furfural and/or furfuryl alcohol by heating it with the bisulphate of an alkali metal, ammonia, or an alkaline earth metal or a mixture of such bisulphates, neutralizing the reaction mixture, and distilling off the tetrahydrofurfuryl alcohol; the bisulphate is used in an amount equal to or less than the amount that will dissolve in the tetrahydrofurfuryl alcohol at room temperature. The bisulphate may be added as a solid, preferably just sufficient to saturate the solution, e.g. 0.5 per cent, or as an aqueous solution, or it may be formed in situ from sodium sulphate and sulphuric acid. In an example, tetrahydrofurfuryl alcohol containing furfural, furfuryl alcohol, and water is purified by refluxing with varying amounts of sodium bisulphate; 15 minutes is the optimum time. Specifications 547,334 and 608,565 are referred to.
