Abstract
Przedmiotem wynalazku jest sposób separacji i zatezania kwasu fumarowego technika elektrodializy bipolarnej z modelowych roztworów wodnych. Sposób separacji i zatezania kwasu fumarowego technika elektrodializy bipolarnej z modelowych roztworów wodnych: jedno-, dwu- i trzyskladnikowych, polega na tym, ze do wodnego roztworu kwasu fumarowego o stezeniu do 6,0 g/dm3 dodaje sie chlorek sodu o stezeniu do 6,0 g/dm3 oraz kwas octowy o stezeniu do 0,6 g/dm3, miesza sie i w trakcie mieszania reguluje sie pH roztworu za pomoca wodorotlenku sodu do pH 8-13, korzystnie 12, a nastepnie mieszanine rozdziela sie w procesie elektrodializy bipolarnej ze stosem elektrodialitycznym zlozonym z polimerowych membran: bipolarnej i anionoselektywnej o calkowitej efektywnej powierzchni stosu równej 6,4 10-3 m2, w pokojowej temperaturze i przy granicznej gestosci pradu w zakresie 50-80 A/m2.The subject of the invention is a method of separation and concentration of fumaric acid by bipolar electrodialysis technique from model aqueous solutions. The method of separation and concentration of fumaric acid by bipolar electrodialysis technique from one-, two- and three-component aqueous solutions consists in the addition of sodium chloride up to 6,0 g / dm3 to an aqueous solution of fumaric acid with a concentration of 6, 0 g / dm3 and acetic acid with a concentration of up to 0.6 g / dm3, mix and, during mixing, adjust the pH of the solution with sodium hydroxide to pH 8-13, preferably 12, and then the mixture is separated in a bipolar electrodialysis process with a stack electrode made of bipolar and anion-selective polymer membranes with a total effective stack area of 6.4 10-3 m2, at room temperature and current limit in the range of 50-80 A / m2.
