Abstract
Inventia se refera la un procedeu pentru obtinerea cisdiclorodiaminoplatinei, conform caruia, folosindu-se ca material de plecare o solutie apoasa filtrata de tetracloroplatinat de potasiu, proaspat si regenerat, în raport cuprins între 8:2 si 9,5 : 0,5 de concentratie 1,2 : 1,4 g/ml, aceasta solutie se trateaza la temperatura ambienta, sub agitare, cu o solutie de iodura de potasiu de concentratie 0,84 g/ml si, în continuare, din amestecul de reactie se precipita cis-diiododiaminoplatina prin tratarea cu solutie de 25% hidroxid de amoniu, la temperatura de 45...55 degree C si racirea ulterioara a amestecului, dupa care iododerivatul separat prin filtrare este uscat sub vid la temperaturi cuprinse în intervalul 45...50 degree C si apoi este supus ampastarii cu o solutie de circa 10% azotat de argint, în cantitate slab substoichiometrica cu agitare ulterioara la 45...55 degree C, obtinîndu-se un complex solubil de diacvadiaminoplatina care este separat prin decantare si filtrare urmate de repetate cicluri de extractie....The invention relates to a process for the preparation of cis d iododiaminoplatin, according to which, using a fresh and regenerated potassium tetrachloroplatinate filtered solution in the ratio of 8: 2 to 9.5: 0.5 of concentration 1.2: 1.4 g / ml, this solution was treated at ambient temperature with stirring with a 0.84 g / ml potassium iodide solution, and the cis- diiododiaminoplatin by treatment with 25% ammonium hydroxide solution at 45-55 ° C and subsequent cooling of the mixture, after which the separated iododerivative by filtration is dried under vacuum at temperatures ranging from 45 to 50 ° C and then subjected to the stamping with a solution of about 10% silver nitrate in a slightly substoichiometric amount with subsequent stirring at 45 ... 55 ° C, obtaining a soluble diacyvaminaminoplatin complex which is separated by decantation and filtration of u Repeated extraction cycles ....
