The influence of technological parameters on the transformation of 1-butene-3-ol (1B3O) to bis(3-methyl- 1-propene) ether (2x1B3O ether) and 3-(3-methyl-1-propene)-3-methyl-1,2-epoxypropane ether (1B3Ox1,2EB3O ether) over the TS-2 catalyst was presented. The reaction was performed in a glass reactor at atmospheric pressure and in methanol medium (protic solvent). The optimum conditions of 2x1B3O ether and 1B3Ox1,2EB3O ether obtaining were established by the mathematical method of experiments design (rotatable-uniform design) and after the analyses of the layer drawings.

The results of epoxidation of 2-butene-1-ol with 30 wt.% hydrogen peroxide have been presented. Methanol was used as a solvent. The process was carried out over titanium silicalite catalyst TS-2. The influence of temperature (20-120.C), molar ratio of crotyl alcohol/H[2]O[2] (5:1-5:1), methanol concentration (5-90 wt.%), catalyst concentration (0.1-5.0 wt.%) and reaction time (30-300 min.) were investigated. The obtained results were utilized for determination of optimum conditions of running 2-butene-1-ol epoxidation process.

W artykule przedstawiono wyniki badań epoksydacji 2-buten-1-olu 30% nadtlenkiem wodoru. Jako rozpuszczalnik zastosowano metanol. Proces prowadzono na katalizatorze tytanowo- silikalitowych TS-2. Zbadano wpływ: temperatury (20-120.C), stosunku molowego alkohol krotylowy/H[2]O[2] (5:1-5:1), stężenia metanolu (5-90% wag.), stężenia katalizatora (0,1-5,0% wag.) i czasu reakcji (30-300 min). Otrzymane wyniki posłużyły do określenia optymalnych parametrów prowadzenia procesu epoksydacji 2-buten-1-olu.

Use of the clathrating compounds and the synthesis methods of the following titanium-silicalite catalysts: TS-1, TS-2, TS-48, ETS-10, [Al,Ti]-BETA were presented. A brief description of their catalytic performance in the oxidation process of olefins, alkanes, alcohols and aromatic compounds was reported. The results of analyses of the catalysts by IR, UV-VIS, XRD, 13C NMR, SEM, TG and DTG methods were also presented. Further directions of our works over the synthesis of titanium-silicalite catalysts and their utilization in the epoxidation processes of the olefine compounds (allyl alcohol, methallyl alcohol, methallyl chloride) and in the hydroxylation of phenol have been discussed. A potential application of obtained products was presented and the possibilities of implementation of developed, low-tonnage technologies of these compounds in Poland were discussed.
