This diploma thesis covers the tracking of final quality parameters of polyether polyol – Slovaprop G-160, which are: amount of sodium and potassium, color, acidity and amount of water. The most important parameter was the amount of sodium and potassium, because the aim this thesis was to achieve satisfactory amount of sodium and potassium after the purification process with use of zeolite (ZeoCem Micro 200) and to improve the effectivity of the purification and filtration process in the production of polyether polyol – Slovaprop G-160. In theoretical part, Diploma thesis deals with the method of production and characteristics of polyether polyols for the production of polyurethane foams. Practical part consists of nine series of experiments in order to get addictions of amount of sodium and potassium to temperature, weight of Pyrofos and amount of zeolite. Based on laboratory test a new way of purification process of polyether polyols was developed. With this new purification process the production time of Slovaprop G-160 will be shorten thanks to removal of hydrolysis from the reaction process and in the end of the process the time needed for drainage is reduced in half.
