  • Process for improving the fragrance properties of macrocyclic compounds obtained by thermal depolymerization
    Patent number: 4331603
    Abstract: A process is provided whereby the malodorous and undesirable constituents present with macrocyclic fragrance compounds obtained by the thermal depolymerization of polyesters are removed. The process involves contacting the macrocyclic compound maintained in a liquid state with ozone or ozone and an aqueous solution of hydrogen peroxide.
    Type: Grant

  • Process for the preparation of vinylcyclopropane derivatives
    Patent number: 4252739
    Abstract: This invention provides a convenient and commercially adaptable process for the preparation of vinylcyclopropane derivatives in high yields. The process involves reacting an alkylating agent and an activated methylene compound in the presence of an onium compound, an alkali metal compound and water, which while only necessary in trace amounts can be present in substantial quantities.

  • Process for the production of macrocyclic esters
    Patent number: 4218379
    Abstract: A process is provided for the continuous or semi-continuous production of hetero-macrocyclic compounds including lactones and cyclic esters. The process involves the catalyzed depolymerization of linear polyesters at elevated temperature and under reduced pressure in the presence of a specified amount of monocarboxylate moieties while providing top-to-bottom mixing throughout essentially the total volume of the reaction mass.
