  • Process to produce valerolactone from levulinic acid
    Patent number: 8598303
    Abstract: The invention provides a process for the preparation of valerolactone, said process comprising reacting levulinic acid with hydrogen by using a solid Ru catalyst, characterized in that the process is carried out in the presence of at least 0.08% (w/w) water relative to the amount of levulinic acid. Said process may be faster and more selective. This process advantageously allows the production of valerolactone from renewable sources. The valerolactone may be used in the preparation of methylpentenoate, adipic acid dimethylester, adipic acid, hexamethylenediamine, and polyamide 6,6 (all claimed).

  • PROCESS FOR THE PRODUCTION OF A COMPOSITION CONTAINING 5'-RIBONUCLEOTIDES
    Publication number: 20130316405
    Abstract: The present invention describes a process comprising a) subjecting a microorganism to autolysis under conditions at which a substantial part of the RNA remains in a form degradable into 5?-ribonucleotides; b) subjecting the autolysate to solid/liquid separation and recovering the RNA-containing cell wall fraction; and c) converting the RNA in the recovered RNA-containing cell wall fraction into 5?-ribonucleotides, whereby the solid/liquid separation in step b) is done at a pH of lower than 5.1. Said process is simple and allows for the production of a very pure composition of 5?-ribonucleotides. It also allows for the production of a very clear yeast extract.
