Safety of rel-(1R,2S)-1,2-Diphenylethane-1,2-diolIn 2020, Chatterjee, Gourav;Shadangi, Krushna Prasad;Mohanty, Kaustubha published 《Effect of Catalyst Bed Height on the Yield and Composition of Non-edible Seed Pyrolytic Oil》. 《Waste and Biomass Valorization》published the findings. The article contains the following contents:
The thermal and catalytic vapor cracking of non-edible seed such as Kassod seed was studied in a fixed bed reactor. The effect of temperature on the yield of pyrolytic liquid was observed from thermal pyrolysis and the optimum temperature was determined At the optimum temperature catalytic vapor cracking using CaO was studied by varying the catalyst loading as well as the bed height. The effect of catalyst loading and bed height on the yield, fuel properties, distillation temperature and composition of pyrolytic oil were determined The results confirmed that thermal pyrolysis of Kassod seed at 550°C yielded 50.21 wt% of pyrolytic liquid containing 39.86 wt% and 10.35 wt% organic and aqueous phase resp. The highest yield of pyrolytic oil (organic liquid) was 31.2 wt% and 22.95 wt% obtained at 2 wt% loading of catalyst at a bed height of 8.5 cm and 11.1 cm resp. The effect of catalytic vapor cracking with the variation in the bed height on the fuel properties confirmed that increasing the catalyst bed height raised the basicity of the pyrolytic oil. The gross calorific value of the oil increased at higher wt% of catalyst loading and were better at the catalyst bed height of 11.1 cm. The catalytic vapor cracking enhanced the fuel properties of the pyrolytic oil by the formation of more volatile components in the pyrolytic oil. The variation in the composition of the pyrolytic oil with and without catalyst was confirmed from the GC-MS anal.rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) were involved in the experimental procedure.

Conversion of meso-hydrobenzoin to trans-stillbene oxide by treatment with an aryl sulfonyl chloride and aqueous sodium hydroxide has been reported.
