Abstract:
A titanium-containing silicon oxide catalyst satisfying all of the following conditions (1) to (4):(1): an average pore size of 10 .ANG. or more,(2): a pore size of 90% or more of the total pore volume of 5 to 200 .ANG.,(3): a specific pore volume of 0.2 cm.sup.3 /g or more, and(4): a quartenary ammonium ion represented by the following general formula (I) is used as a template and then said template is removed by solvent extraction operation;[NR.sup.1 R.sup.2 R.sup.3 R.sup.4 ].sup.+ (I)wherein, R.sup.1 represents a linear or branched hydrocarbon chain having 10 to 36 carbon atoms, and R.sup.2 to R.sup.4 represent an alkyl group having 1 to 6 carbon atoms, and wherein the catalyst has no peak showing an interplanar spacing (d) in a X-ray diffraction.
