Выход изомерных олеиновых кислот при оптимальных услови х (550-575°С, объемна скорость подачи метилстеарата 1,О-1,44 час -1) равен 25,3-26,7%, 48130 3 .4 . |,счита на исходный метилстеарат, при из- бирательности 50-60%, Вли ние окиси цинка на дегидрирующие ° -- свойства цшпсхромовых катализаторов изучают на катализаторах, получен 1ых осаждением хромата цинка на юкись цинка в мол рных соотношени х 1,0:0,5-1,0:3,0. Выходы непредельных кислот в расчете на исходный эфир, полученные при оптимальных услови х дегидрировани {550°С, скорость подачи метилстеарата 1,44 час), приведены в таблице.3 The resulting catalyst is tested in. laboratory conditions in the reaction of dehydration). methyl stearate at ZOO-bbo. ig ,,. the volumetric feed rate of ether O, iS - 2.44 hours and the flow rate of carrier gas 17 l / hour. The yield of isomeric oleic acids under optimal conditions (550-575 ° С, methyl stearate 1 volumetric feed rate, O-1.44 h -1) is equal to 25.3-26.7%, 48130 3 .4. Considering the starting methyl stearate, with a selectivity of 50-60%, the effect of zinc oxide on dehydrating ° — the properties of chromium catalysts are studied on catalysts, obtained by the deposition of zinc chromate on zinc oxide in a molar ratio of 1.0: 0 5-1.0: 3.0. The yields of unsaturated acids based on the starting ester, obtained under optimal dehydrogenation conditions {550 ° C, methyl stearate feed rate 1.44 hours) are listed in the table.
