Description

Zwiazki rteciowe wielowartosciowych fenoli szeregu benzenowego nie mogly do¬ tychczas znalezc zastosowania jako srodki dezynfekcyjne i zaprawy nasion siewnych, gdyz wiekszosc zwiazków tych byla niezna¬ na, a w przypadku gdzie zwiazek podobny zostal opisany (rezorcin — Hg. Dimroth B. 35,2865) praktycznemu zastosowaniu staje na przeszkodzie jego nietrwalosc.Obecnie wykryto, ze rteciowanie wielo- oksyzwiazków szeregu benzenowego zacho¬ dzi w temperaturze zwyklej tak szybko, ze do osiagniecia pozadanego przeksztalcenia wystarczy rozpuszczenie w wodzie suchej mieszaniny skladników. Nader klopotliwe¬ mu oddzielaniu fenolowych zwiazków rte¬ ciowych wedlug znanych dotychczas sposo¬ bów, polaczonemu ze stratami i wymaga¬ jacemu wielokrotnych operacyj, zapobiega sie W mysl wynalazku niniejszego dzieki te¬ mu, ze sucha mieszanine skladników roz¬ puszcza sie w wodzie w sposób nader pro¬ sty; W chwili zetkniecia sie mieszaniny z woda zachodzi jednoczesnie zupelne zwia¬ zanie rteci z odpowiednim fenolem, dzieki czemu po dodaniu lugu sodowego tlenek rte¬ ci nie osiada. W celu przyspieszenia roz¬ puszczania, mozna dodac soli kuchennej lub srodka dzialajacego podobnie. Wskutek kwasnego odczynu stosowanych soli rtecio¬ wych, a niekiedy równiez i fenoli, mieszani¬ ny wykazuja oczywiscie slaby odczyn kwa¬ sny. W przypadkach, gdy w praktyce nie jest to pozadane, mozna reakcje kwasna u- sunac, dodajac alkaljów, np. sody, i w ten sposób otrzymac mieszaniny o odczynie cal¬ kowicie obojetnym. Ponadto istnieje mozli¬ wosc laczenia z innemi rozpuszczalnemi wwodzie srodkami dezynfekcyjnemi. W po¬ równaniu ze znanemi fenolowemi zwiazka¬ mi rteciowemi nowe te mieszaniny posiada¬ ja zalete bezwonnosci. Nietylko jednak mie¬ szaniny same, lecz równiez i wodne ich roz¬ twory sa bezbarwne i trwale; mozna je bez szkody dla ich trwalosci ogrzewac w ciagu kilku godzin od 95-—100°. Dla mozliwie do¬ kladnego zmieszania skladników zaleca sie przezroczysty roztwór odparowac do su¬ cha i pozostalosc sproszkowac. Nowe mie¬ szaniny okazaly sie w praktyce dezynfek¬ cyjnej jako bardzo czynne zaprawy do na¬ sion siewnych, niszczace szkodniki pocho¬ dzenia zwierzecego i roslinnego. Srodki de- Przyklad I. 11 cz. wag. rezorcyny 27 n „ sublimatu PL PLMercury compounds of polyvalent phenols of the benzene series could not be used as disinfectants and seed dressings until now, because most of these compounds were unknown, and in the case where a similar compound was described (resorcinol - Hg. Dimroth B. 35, 2865), its practical application was hindered by its instability. It has now been discovered that the mercuriation of polyoxy compounds of the benzene series takes place so quickly at ordinary temperature that dissolving a dry mixture of the components in water is sufficient to achieve the desired transformation. The extremely difficult separation of phenolic mercury compounds according to previously known methods, which is associated with losses and requires repeated operations, is avoided by the present invention by dissolving the dry mixture of components in water very simply. When the mixture comes into contact with water, complete binding of the mercury to the corresponding phenol occurs simultaneously, so that mercury oxide does not precipitate after the addition of sodium hydroxide solution. To accelerate dissolution, table salt or a similarly effective agent can be added. Due to the acidic reaction of the mercury salts used, and sometimes also of the phenols, the mixtures are naturally weakly acidic. In cases where this is not practical, the acid reaction can be eliminated by adding an alkali, e.g., soda, thus obtaining mixtures with a completely neutral reaction. Furthermore, it is possible to combine them with other water-soluble disinfectants. Compared to known phenolic mercury compounds, these new mixtures have the advantage of being odorless. However, not only the mixtures themselves but also their aqueous solutions are colorless and stable; they can be heated to 95°C to 100°C for several hours without affecting their stability. To ensure the components are mixed as thoroughly as possible, it is recommended to evaporate the clear solution to dryness and pulverize the residue. The new mixtures proved to be very effective disinfectants for seed, destroying pests of animal and plant origin. Example I. 11 parts by weight of resorcinol 27 n " sublimate PL PL
