11. An advertising display device according to claim 9, wherein the connecting means comprise locking parts sliding into each other which allow for connecting two adjacent devices by means of a vertical movement of one housing in respect to the other.
12. An advertising display device according to claim 1, said housing comprising an upper face provided with a top cap, whereby the housing, at least at the foremost upper edge, is provided with an edge frame, said top cap ending up at the edge frame.
13. An advertising display device according to claim 12, the device further comprising a protective element which can be provided at the advertising window, such that it extends between, on one hand, an edge frame provided at the lower edge of the housing and, on the other hand, the aforementioned edge frame provided at the upper edge of the housing.
14. An advertising display device comprising a housing, the front face of which shows an advertising window, as well as means for moving a strip past the window, which strip comprises the images to be advertised, whereby the aforementioned housing, apart from the aforementioned front face, further comprises a rear face, two end faces, an upper face and a bottom face, and whereby at least the upper face is provided with a top cap, characterized in that the housing, at least nearby the foremost upper edge, is provided with an edge frame, and that the top cap ends up at the edge frame.
15. An advertising display device according to claim 14, the device further comprising a protective element which can be provided at the advertising window, such that it extends between, on one hand, an edge frame provided at the lower edge of the housing and, on the other hand, the aforementioned edge frame provided at the upper edge of the housing.
16. An advertising display device according to claim 15, wherein the protective element is removable.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for the catalytic conversion of organic carbonate, wherein organic carbonate is contacted with (i) alcohol, (ii) water or (iii) a mixture of, in the presence of a catalyst comprising at least about 7 wt. % of lanthanum supported on a support.
2. The method as claimed in claim 1, wherein the lanthanum catalyst comprises of from about 7 to about 40 wt. % lanthanum per gram support.
3. The method as claimed in claim 1, wherein the support is selected from Al2O3, SiO2, MgO, TiO2, ZrO2, ZnO and mixtures thereof.
4. The method as claimed in claim 1, wherein the lanthanum catalyst is obtainable by the steps of:
i. loading the support with a lanthanum salt; and
ii. drying and calcining the impregnated support.
5. The method as claimed in claim 4, wherein the lanthanum salt is selected from lanthanum chloride, lanthanum acetate and lanthanum nitrate.
6. The method as claimed in claim 1, wherein the organic carbonate is subjected to hydrolysis with water.
7. The method as claimed in claim 1, wherein the organic carbonate is subjected to alcoholysis with alcohol.
8. The method as claimed in claim 1, wherein organic carbonate is subjected to hydrolysis and alcoholysis in the presence of water and alcohol.
9. The method as claimed in claim 7, wherein the alkylene carbonate is propylene carbonate and the alcohol is methanol.
10. The method as claimed in claim 1, wherein the lanthanum catalyst comprises from about 8 to about 30 wt % of lanthanum per gram of support.
