| titleOfInvention | Process for the production of sigma and epsilon lactones |
| abstract | Method for producing delta - and epsilon -lactones of formula (I), in which the radical R may be the same or different, and stand for hydrogen, optionally substituted aliphatic, cycloaliphatic, aromatic, araliphatic or heterocyclic radicals, which can also be optionally bond to an oxygen atom of C atom and n stands for the numbers 3 or 4. According to said method, dialdehyde of the formula (II) OCH- (CR2)n-CHO, wherein R and n have the meaning cited above, or the mono- and the dihydrates and/or the mono- and the dihemiacetales of said dialdehydes are made to react in heterogeneous catalyzers during the gas or liquid phase at temperatures ranging from 20 to 300 DEG C and pressures ranging from 0.1 to 100 bar and the lactones are obtained in pure form by distillation. |
