    Abstract: A PROCESS FOR THE PRODUCTION OF STYRENE BY CATALYTIC DEHYDROGENATION OF ETHYLBENZENE WITH OXYGEN OF A GAS CONTAINING MOLECULAR OXYGEN IN THE PRESENCE OF STEAM IN A FLUIDIZED BED AT A TEMPERATURE OF FROM 350* TO 600*C. USING A SOLID CATALYST AND REGENERATING THE CATALYST BY BURNING OFF THE CARBONACEOUS DEPOSITS, WHICH COMPRISES CARRYING OUT THE REGENERATION OF THE CATALYST, WITH INCOMPLETE BURNING OFF OF THE CARBONACEOUS DEPOSITS WITH OXYGEN OR A GAS CONTAINING MOLECULAR OXYGEN, ONLY TO SUCH AN EXTENT THAT ON AN AVERAGE THE CATALYST CONTAINS DURING THE REACTION FROM 1 TO 30% BY WEIGHT OF THESE CARBONACEOUS DEPOSITS WITH REFERENCE TO THE CATALYST. STYRENE IS A VALUABLE MONOMER FOR THE PRODUCTION OF PLASTICS.

    Abstract: 1415206 Textile-treating urea-formaldehydeglyoxal resins BADISCHE ANILIN- & SODAFABRIK AG 2 March 1973 [3 March 1972] 10214/73 Headings C3R and C3P [Also in Divisions D1-D2] A textile-treating resin is obtained by condensing urea with formaldehyde in a 1 : 2-10 molar ratio in aqueous solution at pH 7-10 and 20-80‹ C. for 0À5-4 hours, then at pH 31-5 and 20-100‹ C. until 5 drops of the solution produce turbidity in 10 ml. of 50% aqueous MgSO 4 .7H 2 O, then adding urea, glyoxal and optionally formaldehyde and heating at pH 5-7 and 20-60‹ C. for 1-6 hours, the final molar ratio of urea : formaldehyde : glyoxal being 1 : 1À5-2À5 : 0À3-0À6. In Examples 1-4 initial condensates of U : F ratio 1 : 4 are acidified with H 2 SO 4 or H.COOH to pH 3À5 to 4À8, heated at 35-90‹ C. for 20 mins to 4 hours and neutralized with NaOH; urea and glyoxal (and in Ex. 4 formalin) are added and the mixture heated at 50-55‹ C. for 3-4 hours; the U : F : G ratios of the products are 1 : 2-2À24 : 0À4-0À5. In Examples 5-7 cotton fabrics are treated with aqueous compositions containing the product of Ex. 2 or 3 and MgCl 2 alone or with a polyethylene emulsion or polyvinyl acetate/ starch mixture.
