  • Method for storing cooling agents
    Patent number: 10589241
    Abstract: The invention relates to a method for the storage of cooling agents without caking, characterized in that the latter are filled into standard packages having a maximum capacity of 25 l, with the proviso that (a) the packages are filled to 50% maximum, and (b) the amount filled into the package does not exceed 10 kg.
    Type: Grant
    Filed: February 11, 2016
    Date of Patent: March 17, 2020
    Assignee: Symrise AG

  • Spherical Menthol Particles
    Publication number: 20090011238
    Abstract: The invention relates to a process for the preparation of spherical menthol particles, comprising the following steps: preparation of a menthol melt, metering of the menthol melt into water having a temperature in the range of from 0 to 12° C., wherein the metering conditions are so chosen that menthol drops are temporarily present in the water after the metering, which menthol drops then solidify in the water to form the spherical menthol particles.

  • Process for preparing C5 acetate
    Patent number: 6541660
    Abstract: A process is proposed for preparing C5 acetate for Vitamin A synthesis by hydroformylation of 3,4-diacetoxybut-1-ene (3,4-DABE), according to which a 3,4-DABE is used which is obtained by acetoxylation of 1,3-butadiene with acetic acid and air in the presence of a catalyst and removing by distillation the 3,4-DABE formed in this case as by-product.
    Type: Grant
