On December 8, 2017, Wang, Yingdong; Li, Shibin; Zha, Yanji published a patent.HPLC of Formula: 38939-88-7 The title of the patent was Method for preparing 2B oil by catalytic hydrogenation. And the patent contained the following:
The invention discloses a method for preparing 2B oil by catalytic hydrogenation. The method comprises the steps of: adding water and chloro-4-methylnitrobenzene at the weight ratio of 1:(3-10) to a hydrogenation reactor, regulating pH to 8-9 with sodium hydroxide, then adding carbon-supported platinum catalyst that is no less than 1% of total mass of the system, performing replacement with nitrogen, heating to 70-75 °C, introducing hydrogen, controlling the reaction pressure at 0.7-0.8 MPa, reacting until there is no hydrogen absorption, discharging the material after the reaction, layering, and rectifying to obtain 2B oil. The method prepares 2B oil by hydrogenation reaction between hydrogen and chloro-4-methylnitrobenzene under the action of the metal catalyst, saves energy, protects the environment, and has low unit consumption for production and high quality of product. The method has the nitro conversion ratio of 99.61%, dechlorinated product content as low as 0.16% and residual nitro compound content as low as 0.03%. The experimental process involved the reaction of 2-Chloro-4-methyl-1-nitrobenzene(cas: 38939-88-7).HPLC of Formula: 38939-88-7
