Beschreibung
Zusammenfassung:	A homogenous mesoporous phosphated titanium siliceous material having acid properties. It is characterized by a high content of acid centers (0.5-2.1 mmol. parts according to thermally programmable ammonium desorption), homogenous mesoporous structure (value of half-width of mesopores distribution as per sizes in the range of 0.39-0.58 nm and high sorption characteristics (high specific surface in the range of 510-900 m2/g, pores volume - 0.28-0.72 cm3/g and adsorption of n-hexane of 15.6-32.2 % by weight ).
