| titleOfInvention | Method for producing gamma valerolactone from levulinic acid |
| abstract | The present invention relates to a process for the preparation of gamma valerolactone (GVL) from levulinic acid (LA), which process comprises (a) contacting LA with a solid catalyst system comprising a support and a metal on the liquid, To obtain a first reaction mixture comprising GVL, hydroxepentanoic acid (4-HPA) and water; (b) removing water from the first reaction mixture; And (c) subjecting the mixture obtained in step (b) to further reaction under conditions suitable for converting the 4-HPA to GVL to obtain an additional reaction mixture. Steps (b) and (c) can be integrated. Optionally, water may be removed from the further reaction mixture. The process optionally comprises recycling the at least partially dehydrated further reaction mixture back to step (b). This step is particularly advantageous when the first reaction mixture is less or even absent in levulinic acid. Alternatively, the GVL may be recovered by distilling the additional reaction mixture or the at least partially dehydrated additional reaction mixture and collecting the distillate. |
