Abstract
The invention relates to a method for carrying out photochemical and thermochemical solar syntheses by means of flat-bed solar light collectors without devices for focusing the sunlight. The method is particularly well suited for producing flavors, aromas and complex thereof. The flat-bed solar light collector is suitable especially for producing steroids and derivatives thereof. It can further be used for the photooxidation (photooxygenation) of terpene olefins and therefore for the synthesis of fragrants such as rose oxide, myrtenol and myrtenal which are of industrial interest. The solar collector is also suitable for photochemical addition reactions and rearrangements.
Claims14
A process for producing a desired product, said process comprising the following steps:
- a) providing at least one flat-bed solar light collector comprising at least one reaction chamber;
- b) introducing one or more reactants to the at least one reaction chamber, said one or more reactants being unsupported, and said one or more reactants being different in said desired product;
- c) irradiating the reaction chamber with direct or diffused sun light or direct or indirect artificial light without a device for focusing the light, said irradiating causing the one or more reactants to undergo a reaction to produce said desired product or a precursor of said desired product;
- and
- d) in case step c) yields said desired product, purifying said desired product;
- or
- e) in case step c) yields a precursor of said desired product, converting said precursor to said desired product.
