Abstract: [cze] [eng]
Práce se zabývá laboratorní separací methanolu z azeotropické směsi (25 wt% methanol a 75 wt% trimethylborát). Byly testovány 4 různé průmyslově vyráběné membrány. U všech kromě jedné separace probíhala více méně úspěšně. U PVA 4155-80/2871 separace probíhala s dobrými výsledky, ale velice pomalu, podmínkou, která by mohla zvýšit rychlost reakce by mohlo být zvýšení teploty. Nejlépe z membrán od společnosti Sulzer dělila PDMS 4155 -30/305 R, která separovala MeOH s vysokou účinností a také dostatečně rychle. Naprosto opačný efekt pak měla membrána PDMS 4060, která místo MeOH separovala Trimethylborát. The work deals with laboratory separation of methanol from the azeotropic mixture (25 wt% methanol and 75 wt% trimethylborate). Four different manufactured membranes were tested. For all except one separation, separation was more or less successful. With PVA 4155-80 / 2871 the separation proceeded with good results, but very slowly, a condition that could increase the reaction rate could be an increase of temperature. Most selective membrane from Sulzer was PDMS 4155 -30/305 R, which separated MeOH with high efficiency and fast enough. The completely opposite effect than pervious membranes had the membrane PDMS 4060, which instead of MeOH separated Trimethylborate.
