Description
Wielokrotnie próbowano juz uzyc fluor¬ ku boru do polimeryzacji olefinów, lecz w odniesieniu do olefinów gazowych nie uda¬ walo sie Jo dotychczas, Zapomoca prób udalo sie stwierdzic, ze polimeryzacja wymienionych weglowodo¬ rów udaje sie bardzo dobrze przy dowol¬ nych temperaturach, nawet przy tempera¬ turze pokojowej i nizszej, jezeli zastosuje sie dzialanie cisnienia.Polimeryzowane weglowodory nie mu¬ sza byc czyste, mozna polimeryzowac we¬ glowodory same lub jako mieszaniny z in- nemi zwiazkami, mozna je równiez poli¬ meryzowac w roztworach.Zamiast fluorku boru mozna uzywac podwójnych (zwiazków fluoru lub jego roz¬ tworów. Przebieg reakcji mozna znacznie ozywic zapomoca domieszki rozdrobnio¬ nych metali, np. niklu.Przyklady: 1. Mieszanine zawierajaca 10 czesci wagowych etylu i 1 czesc wagowa fluorku boru pozostawia sie pod cisnieniem samej sobie, przyczem nie jest konieczna temperatura wyzsza od temperatury poko¬ jowej. W ten sposób zaleznie od trwania reakcji mozna przemienic do 80% etylenu na plynne produkty polimeryzacyjne. 2. Mieszanine 10 czesci wagowych technicznego gazu blekitnego (zawierajace¬ go 60% objetosciowych olefinów) ii czesci wagowej fluorku borowego przerabia sie tak samo jak pod 1. Ilosc otrzymanych pro¬ duktów polimeryzacji wynosi 60% wago* wych przerabianego gazu. 2. W naczyniu o pojemnosci 600 cm3przerabia sie pod cisnieniem 70 atm 10 g fluorku borowego i 100 g etylenu. Po 12 godzinach bez dodatku niklu ulega polime¬ ryzacji 20 g, natomiast z domieszka niklu polimeryzacja etylenu jest calkowita w przeciagu 3 doi 4 godzin. PLThere have been many attempts to use boron fluoride for the polymerization of olefins, but with regard to gaseous olefins, Jo has not been successful so far. Following attempts it has been found that the polymerization of these hydrocarbons has been successful at any temperature, even At room temperature and at lower temperatures, if you apply pressure. Polymerized hydrocarbons do not have to be pure, you can polymerize the hydrocarbons alone or as mixtures with other compounds, they can also be polymerized in solutions. Instead of boron fluoride, you can use double (fluorine compounds or its solutions. The course of the reaction can be greatly enhanced by admixtures of particulate metals, e.g. nickel. Examples: 1. A mixture of 10 parts by weight of ethyl and 1 part by weight of boron fluoride is left under the pressure of itself, therefore it is not necessary to have a temperature above room temperature. In this way, depending on the duration of the reaction, it is possible to convert up to 80 % ethylene for liquid polymerization products. 2. A mixture of 10 parts by weight of technical blue gas (containing 60% by volume olefins) and a part by weight of boron fluoride is processed in the same way as under 1. The quantity of polymerization products obtained is 60% by weight of the gas processed. 2. 10 g of boron fluoride and 100 g of ethylene are processed under a pressure of 70 atm. In a 600 cm3 vessel. After 12 hours without the addition of nickel, 20 g are polymerized, while with the addition of nickel, the polymerization of ethylene is complete within 3-4 hours. PL
