Abstract
The invention relates to a method for producing limonene comprising or consisting of the following steps: (a) providing beta-pinene or a beta-pinene containing starting material; (b) admixing the starting material with a catalytically effective amount of a MWW-type zeolite; (C) heating the reaction mixture to a temperature in the range of between 60 and 100° C.; and optionally (d) separating the limonene or a limonene-enriched fraction from the sump.
Claims15
A process for producing limonene, comprising the steps of:
- (a) providing beta-pinene or a beta-pinene-containing starting material;
- (b) admixing the starting material with a catalytically active amount of an MWW-type zeolite;
- (c) heating the reaction mixture to a temperature in the range from about 60° C. to about 100° C.;
- and optionally
- (d) separating the limonene or a limonene-enriched fraction from the bottoms.
2 more elements
A solvent composition consisting of
- (a) about 70 to about 80% by weight of limonene, and
- (b) about 15% to about 20% by weight of camphene,
- with the proviso that the reported amounts sum to 100% by weight optionally with pinenes, terpinenes and terpinolenes.
