  • Process for isolating crystallized 2,2,4,4 tetramethyl-1,3-cyclobutanediol (TMCD) particles utilizing pressure filtration
    Patent number: 9024080
    Abstract: A method for isolating 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) solids from an isolated feed slurry formed in a TMCD process comprising TMCD, a liquid phase, and impurities by (a) treating the isolated feed slurry in a product isolation zone to produce an isolated TMCD product wet cake, a mother liquor, and impurities; wherein the product isolation zone can comprise at least one rotary pressure drum filter.
    Type: Grant

  • Process for the recovery of a phytolipid composition
    Publication number: 20050053712
    Abstract: Disclosed is a process for the recovery of a phytolipid composition from a vegetable oil by-product. The phytolipid composition produced comprises squalene, phytosterols, mixed tocopherols and tocotrieneols, and vegetable wax and is useful as an emollient. The phytochemical composition may be applied directly to the skin to provide emolliency. Alternatively, the phytolipid composition may be formulated in various aqueous or anhydrous cosmetic compositions such as creams, lotions, gels, ointments, lip balms, sticks, or pencils for treatment of the skin and lips. The phytolipid composition also may be incorporated into foods, beverages, and nutraceuticals to provide health benefits.
