| description | An important product of biomass carbohydrate conversion is 5-hydroxymethylfurfural as a potential raw material component of a wide range of important chemicals. The aim of the work was to study the conversion of glucose into 5-hydroxymethylfurfural in the presence of modified clinoptilolite and mordenite-clinoptilolite zeolite rocks from Transcarpathia. A number of acid catalysts have been synthesized by liquid-phase ion exchange of native cations with calcium, lanthanum, and ammonium cations, as well as by dealumination with hydrochloric and ethylenediaminetetraacetic acid. Their properties were characterized using XRD and XRF analysis, low-temperature nitrogen adsorption/desorption, and FTIR spectroscopy. The acidity of the samples was determined by reverse n-butylamine titration. Acid treatment of the samples contributed to an increase in the specific surface area of the samples by an order of magnitude. The samples were tested in the conversion of 9% aqueous glucose solution into 5-hydroxymethylfurfural. The composition of the reaction products was analyzed by gas chromatography. The glucose conversions and the yields of 5-hydroxymethylfurfural, levulinic acid, and fructose were calculated. The glucose conversions ranged from 30 to 70 %. The results were analyzed in accordance with the characteristics of the nature of the active sites of the catalysts and the porous structure of the latter. It was found that the samples with the presence of Lewis acid sites in the form of extra-framework aluminum and multiply charged cations are characterized by the highest 5-hydroxymethylfurfural yields. Due to glucose conversion occurs mainly on the outer surface of zeolite crystals and at the entrances to the cavities, the polycationic form of clinoptilolite, despite its low porous characteristics, demonstrates the highest yield of            5-hydroxymethylfurfural. |

Важливим продуктом перетворення вуглеводів біомаси є 5-гідроксиметилфурфурол як потенційний сировинний компонент широкого ряду важливих хімічних речовин. Метою роботи було дослідження конверсії глюкози до 5-гідроксиметилфурфуролу в присутності модифікованих клиноптилолітової та морденіт-клиноптилолітової цеолітових порід Закарпаття. Синтезовано ряд кислотних каталізаторів шляхом рідкофазного іонного обміну нативних катіонів на катіони кальцію, лантану та амонію, а також шляхом деалюмінування хлоридною та етилендіамінтетраоцтвою кислотою. Охарактеризовано їх властивості за допомогою рентгено-фазового та рентгенофлуорисцентного аналізу, низькотемпературної адсорбції/десорбції азоту та ІЧ-спектроскопії. Здійснено оцінку кислотності зразків за титруванням з н-бутиламіном. Кислотна обробка зразків сприяла зростанню питомої поверхні зразків на порядок. Зразки випробувано у перетворенні 9 % водного розчину глюкози до                                                  5-гідроксиметилфурфуролу. Склад продуктів реакції аналізували за допомогою газової хроматографії. Було розраховано конверсії глюкози та виходи 5-гідроксиметилфурфуролу, левуліновї кислоти та фруктози. Конверсії глюкози склали від 30 до 70 %. Результати проаналізовано у відповідності до особливостей природи активних центрів та пористої структури каталізаторів. Встановлено, що найкращі виходи 5-гідроксиметилфурфуролу характерні для зразків із наявністю льюїсових кислотних центрів у вигляді позакаркасного алюмінію та багатозарядних катіонів. Оскільки перетворення глюкози перебігає переважно на зовнішній поверхні цеолітних кристалів та у входах у порожнини, то полікатіонна форма клиноптилоліту, незважаючи на її низьку пористість, демонструє найвищий вихід                                        5-гідроксиметилфурфуролу.
