  • Patent number: 10556876
    Abstract: The invention relates to process for the preparation of gamma valerolactone (GVL) from levulinic acid (LA), said process comprising a) subjecting LA to a hydrogenation reaction comprising hydrogen and a solid catalyst system comprising a metal and a support in the liquid phase, to yield a first reaction mixture comprising GVL, hydroxypentanoic acid (4HPA), and water; b) removing water from said first reaction mixture; and c) subjecting the mixture obtained in step b) to a further reaction under conditions suitable to convert said 4-HPA to GVL, to yield a further reaction mixture.

  • Patent number: 10531664
    Abstract: A method of stabilizing aqueous solutions of antimicrobial silanol quaternary ammonium compounds (SQACs) from premature polymerization where the stabilizing agent is selected from a list of antimicrobial, naturally occurring, renewable, volatile, liquid phytochemical essential oils that easily form crystal clear microemulsions when water is added to the concentrated SQAC/essential oil mixture. These non-foaming oil-in-water microemulsions have excellent long term storage stability, remain very low in viscosity and do not phase or precipitate for many months. Many essential oils found to be useful in this process are non-toxic food additives having pleasant scents, have low flammability yet are volatile enough to evaporate upon cure down of the SQAC, resulting in a higher concentration of SQAC in the cured, antimicrobial film.

  • Patent number: 10519124
    Abstract: Disclosed herein are methods for synthesizing 1,2,5,6-hexanetetrol (HTO), 1,6 hexanediol (HDO) and other reduced polyols from C5 and C6 sugar alcohols or R glycosides. The methods include contacting the sugar alcohol or R-glycoside with a copper catalyst, most desirably a Raney copper catalyst with hydrogen for a time, temperature and pressure sufficient to form reduced polyols having 2 to 3 fewer hydoxy groups than the starting material. When the starting compound is a C6 sugar alcohol such as sorbitol or R-glycoside of a C6 sugar such as methyl glucoside, the predominant product is HTO. The same catalyst can be used to further reduce the HTO to HDO.
