Description

Najdluzszy czas trwania patentu do 27 maja 1940 r.Okazalo sie wedlug niniejszego wyna¬ lazku, ze sposób wytwarzania perylenu przez pyrogeniczna redukcje dwuoksype- rylenu, stanowiacy przedmiot patentu Nr 2131, przebiega znacznie prosciej i bez produktów ubocznych przy dodawaniu do masy reakcyjnej zwiazków, wiazacych wo¬ de, jak, np., chlorek wapniowy, magnezo¬ wy, glinowy i tym podobny i, w danym ra¬ zie, przez destylacje przy wprowadzeniu przegrzanej pary.Przyklad. 2 czesci 1—12-dwuoksype- rylenu zostaja dokladnie roztarte z 3 cz, pylu cynkowego i 3 cz, stopionego chlorku wapniowego, do których dodaje sie 1 cz, wody i rozgrzewa szybko az do rozpoczy¬ najacej sie destylacji perylenu. Wytwa¬ rzajacy sie perylen oddestylowuje sie przy przepuszczaniu, w danym razie, przegrza¬ nej pary i moze byc wykrystalizowany z toluolu, jednak i surowy produkt jest do¬ statecznie czysty dla otrzymywania po¬ chodnych. PLThe longest term of the patent until May 27, 1940, it turned out, according to the present invention, that the method of producing perylene by pyrogenic reduction of dioxirylene, which is the subject of patent No. 2131, is much simpler and without by-products when adding compounds to the reaction mass to bind water, such as, for example, calcium chloride, magnesium chloride, aluminum chloride and the like, and, where appropriate, by distillation with the addition of superheated steam. 2 parts of 1-12-dioxypyrylene are thoroughly ground with 3 parts of zinc dust and 3 parts of molten calcium chloride to which 1 part of water is added and heated rapidly until the perylene distillation begins. The perylene that is formed is distilled by passing superheated steam, if any, and may be crystallized from toluol, however, the crude product is sufficiently pure for the preparation of derivatives.
