Related Products of 2516-33-8 ,Some common heterocyclic compound, 2516-33-8, molecular formula is C4H8O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
General procedure: The gas-phase selective oxidation of alcohols on these catalysts with molecular oxygen was carried out on a fixed-bed quartz tube reactor (i.d., 16 mm) under atmospheric pressure as described previously [14,15,26,27]. Circular chips (16.1 mm diameter) of the microfibrous-structured Au/Ni-fiber catalysts were punched down from their large sheet sample and packed layer-up-layer into the tube reactor with total mass of 0.3 g. Note that the diameter of 0.1 mm larger than the i.d. of the tubular reactor was retained deliberately to avoid the appearance of the gap between the reactor wall and the edges of the catalyst chips thereby preventing the gas bypassing. Alcohols were fed continuously using a high-performance liquid pump, in parallel with O2 (oxidant) and N2 (diluted gas) feeding using the calibrated mass flow controllers, into the reactor heated to the desired reaction temperature. The organic phase of the liquid effluent was collected for analyzing by an HP 5890 gas chromatography-flame ionization detector (GC-FID) with a 60-m HP-5 ms capillary column. The gas-phase products such as H2, COx, and C1-C3 hydrocarbons were analyzed by an HP-5890 GC with thermal conductivity detector (TCD) and a 30-m AT-plot 300 capillary column. Reaction temperature, WHSV, and alcoholic hydroxyl (O2/ol) were varied in range from 220 to 380 C, 10 to 70 h-1, and 0.4 to 1.2, respectively. Prior to the reaction testing, as-prepared catalysts were all activated by performing the benzyl alcohol oxidation at a high temperature of 380 C for 1 h, using molar ratio of O2 to O2/ol = 0.6 and WHSV = 20 h-1.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,2516-33-8, its application will become more common.
