Abstract

The Provisional Specification describes the preparation of aluminium silicate comprising mixing solutions of sodium hydroxide and sodium silicate in amounts such that the silicate conforms to Na2SiO3 and adding the mixture to a solution of aluminium nitrate in amounts such that the ratio of Al2O3 to SiO2 is 1 : 1. The compound is a catalyst for the conversion of levulinic acid or its esters to methyl vinyl ketone (see Group IV (b)).ALSO:Methyl vinyl ketone is produced by heating alpha or beta angelica lactone or levulinic acid or an ester thereof in the vapour phase at a temperature of from 450 DEG to 650 DEG C. The reaction may be carried out in a vessel packed with filling bodies such as silica chips or pumice, in the presence of a dehydrating or cracking catalyst such as aluminium silicate or in an unpacked vessel. If desired, angelica lactone may be prepared in situ and the process then carried out in several stages. In examples, the ketone is prepared (1) by passing alpha angelica lactone or levulinic acid over silica chips at 570 DEG C.; (2) by passing levulinic acid over basic aluminium phosphate at 350 DEG -360 DEG C. and then passing the exit vapours over heated silica chips as in (1). Specification 453,518 is referred to. The processes described in the Provisional Specifications are not limited to the use of the above temperatures; both Specifications describe the preparation of the abovementioned aluminium silicate comprising heating a mixed solution of sodium hydroxide and sodium silicate with a solution of aluminium nitrate (see Group III).
