Abstract:
The present invention relates to a product comprising squalene according to Formula I in an amount of equal or more than 50 wt.-% related to the total weight of the product according to Formula I, the product being produced by a continuous flow, microwave assisted process comprising the steps: a) preparing a reaction mixture containing an oily or fatty material of plant origin and aqueous methanol or aqueous ethanol, b) continuously conveying of the reaction mixture through a microwave-transparent reaction zone and irradiating the reaction mixture with microwaves inside the reaction zone in the presence of an acidic catalyst, whereby the retention time of the reaction mixture in the microwave-transparent reaction zone is 1 s to 180 s, the temperature in the reaction zone being equal to or between 100 °C and 220 °C, the pressure in the reaction zone being 1.5 bar to 30 bar, wherein a reaction of the reaction mixture takes place in the reaction zone resulting in a mixture of polar substances comprising glycerol, methanol or ethanol, and water, and non-polar substances comprising fatty acid methylesters or fatty acid ethylesters and unsaponifiable components, c) releasing the pressure to ambient pressure, d) after phase separation the polar phase is separated from the non-polar phase containing the non-polar substances, e) separating fatty acid methylesters or fatty acid ethylesters from the non-polar phase by falling film evaporation or thin-layer evaporation, f) separating squalene according to Formula I from the unsaponifiable components by molecular distillation, short-pass distillation, extraction or freeze separation.
Abstract:
Provided herein are methods comprising catalytic dimerization of ß-farnesene to obtain squalane and/or isosqualane. Compositions comprising squalane and/or isosqualane are provided. In certain embodiments, squalane and isosqualane prepared by the methods provided herein can be useful for applications in cosmetic industry and/or in the lubricants industry.
Abstract:
The invention relates to a method for the ethenolysis of acyclic polyterpenes which comprise trisubstituted double bonds. The polyterpene is reacted with a catalyst complex [(NHC)(NHCewg)MeX2(CHPh)] and [(NHC)(NHCeWg)MeX2(3-phenylindenylid-1-ene)] in the presence of ethene. NHC and NHCewg are N-heterocyclic carbene ligands, where NHC is at least as rich in electrons as NHCewg, Me is Ru, Os or W, and X is selected from F, Cl, Br, I, CN, SCN, OCN, and NCO. The polyterpene is particularly advantageously selected from natural rubber, liquid natural rubber and squalene, or from vulcanized rubber, selected from used tires, used tire granules and powdered rubber. The invention provides, for the first time, decomposition products of the polyterpenes natural rubber, liquid natural rubber, squalene and vulcanized rubber, which can be produced with the aid of the method according to the invention.

Abstract:
An improved method for preparing squalene from a squalene-containing composition, said method comprising the steps of (a) a purification distillation carried out at a temperature T 1 ; (b) a denaturing distillation carried out at a temperature T 2 ; wherein steps (a) and (b) may be performed in either order; T 1 and T 2 are sufficient to cause squalene to boil; T 2 > T 1 ; and T2 > 200°C.
Abstract:
An in-situ method for making a conjugated diene from an allyl alcohol comprising the conversion of the allyl alcohol to an allyl carbonate, allyl ester or allyl formate with concomitant or subsequent conversion of the allyl carbonate, allyl ester or allyl formate to the conjugated diene; the products obtained by said method, and the uses of said products.
Abstract:
Pharmaceutical compositions comprising a mixture of cannabinoids and terpenes and use thereof in the treatment of select disorders mediated by the Hedgehog (HH) signaling pathway are disclosed. In preferred embodiments, the components of the composition synergistically inhibit HH signaling such that they serve to treat cancer and ocular disorders associated with aberrant neovascularization (such as age-related macular degeneration). The cannabinoids to be used include phytocannabinoids (such as tetrahydrocannabinol and cannabidiol), endogenous cannabinoids (such as the N-acylethanolamides), or synthetic cannabinoids. Preferred terpenes for use include those that naturally occur in Cannabis plants (such as pinene, limonene, linalool, and phytol).
Abstract:
The invention relates to a process for the dimerization of conjugated diene compounds by a heterogeneous catalytic process using a supported palladium catalyst in the presence of at least one palladium activator and at least one palladium coordinating agent.
