Abstract

Fotochemický reaktor s ultrazvukovým miešaním reakčnej zmesi je určený pre fotochemická syntézu látok a pozostáva z piezoelektrického meniča, ktorý je' pritmelený na vonikajší plášť fotoreaktora a prostředníctvom ktorého dochádza k premene elektrickej energie na ultrazvuková energiu, ktorá sa šíři reakčnou zmesou a zabezpečuje jej dokonalé miešanie.The photochemical reactor with ultrasonic mixing of the reaction mixture is intended for photochemical synthesis of substances and consists of a piezoelectric transducer, which is glued to the outer shell of the photoreactor and through which electrical energy is converted into ultrasonic energy, which propagates through the reaction mixture and ensures its perfect mixing.

Description

(Vynález sa týtka fotochemického reaktora s ultrazvukovým miešaním reakčnej zmesi.(The invention relates to a photochemical reactor with ultrasonic mixing of the reaction mixture.

Doteraz vyrábané fotochemické reaktory sú 'konstruované tak, že reakčná zmes nie je miešaná alebo talk, že miešanie reakčnej zmesi je zabezpečené magnetickým miešadlom, resp. nějakým iným klasickým miešadlom, prebublávaním reakčnej zmesi inertným plynom, alebo núteným obehom reakčnej zmesi. Výhodou reiaktorov s uvedeným typom miéšania je, že sa miešaním čiastočne obmedzí tvorba vedlajších produktov, avšak uvedené typy miešania reakčnej zmesi nezaručujú dostatočnú turbulenciu roztoku, čo má za následok nedostatečné obmedzenie vzniku nežiadúcich produktov.The photochemical reactors so far produced are designed such that the reaction mixture is not stirred or agitated so that the stirring of the reaction mixture is ensured by a magnetic stirrer or a magnetic stirrer. by some other conventional stirrer, by bubbling the reaction mixture through an inert gas or by forced circulation of the reaction mixture. The advantage of the relators with this type of mixing is that the formation of byproducts is partially reduced by mixing, but the mentioned types of mixing of the reaction mixture do not guarantee sufficient solution turbulence, resulting in an insufficient restriction on the formation of undesirable products.

Tento nedostatek fotochemických reaiktorov je odstraněný ivo fotochemickom reaktore s ultrazvukovým miešaním podlá vynálezu, ktorého podstata spočívá v tom, že tento pozostáva z reakčnej nádoby foto- chemického reaktora, piezoelektrického meniča a vysolkofrekvenčného zdroja.This drawback of photochemical reactors is an ultrasonic-agitated photochemical reactor according to the invention, which consists of a reaction vessel of a photochemical reactor, a piezoelectric transducer and a radio frequency source.

Fotochemický reaktor s ultrazvukovým miešaním zvyšuje selektivitu fotochemických syntéz a iv porovnaní s klasickými metodami používanými na miešanie vo fotochemických reaktoroch je konštrukčne jednoduchý a vysoko účinný.The photochemical reactor with ultrasonic mixing enhances the selectivity of photochemical syntheses and is structurally simple and highly efficient in comparison with conventional methods used for photochemical reactor mixing.

Fotochemický reaktor podlá vynálezu možno použit zvlášť pri syntézách, pri ktorých dochádza k asorpcii světla aj reakčným produktom a v prípadoch, ked' koncentrácia reakčných zložiek je vysoká.The photochemical reactor according to the invention can be used in particular for syntheses in which light is absorbed by the reaction product and in cases where the concentration of the reactants is high.

Na priloženom výkrese je znázorněný fotochemický reaktor s ultrazvukovým miešaním reakčnej zmesi. Pre jednoduchost je zobrazená len tá časť reaktora, ktorá sa líši od běžných reáktorov s inertným zdrojom světla. Nadstavba může byť použitá podlá potřeby užívatela.The accompanying drawing shows a photochemical reactor with ultrasonic mixing of the reaction mixture. For the sake of simplicity, only that portion of the reactor that differs from conventional inert light sources is shown. The superstructure can be used as required by the user.

Reakčná nádoba 1 je zhotovená tak, aby mala rovné dno, na ktoré je pritmelený piezoelektrický měnič 2, ktorý je připojený na vysolkhfrekvenčný generátor 3.The reaction vessel 1 is configured to have a flat bottom onto which the piezoelectric transducer 2, which is connected to the high frequency generator 3, is bonded.
