    摘要: A process for the manufacture of pivalolactone from the anhydride of a Beta -acyloxypivalic acid or the mixed anhydride of a Beta -acyloxypivalic acid with a low aliphatic carboxylic acid with up to 5 carbon atoms by thermal splitting at temperatures within the range of from 150*C to 350*C on catalysts supported on carriers.
