Synthetic Route of 118-69-4, A common heterocyclic compound, 118-69-4, name is 2,6-Dichlorotoluene, molecular formula is C7H6Cl2, 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.
Ammoxidation runs were carried out in a fixed bed tubular quartz reactor, which is filled with 5g of catalyst particles prepared by the methods described in examples 1 to 3 and mixed with corundum particles of the same size in 1: 1 by weight ratio. A preheating zone is provided on the top of the catalyst bed. The catalyst was activated in a mixture of air and [NH3] at [400C] for 4 hours and then the catalytic runs were performed. The 2,6-DCT and [H20] were pumped in the mole ratio of 1: 15 to 20. The product stream was collected for every half-an-hour and analysed by gas chromatography. The reaction was carried out under the following reaction conditions. A reaction temperature of 350 to [400C] was used, and the GHSV comprised between 650-750 [H-‘.] The contact time consisted of 4.8 to 5.5 seconds. The mole ratio of 2,6-DCT : H20 : NH3: air was 1: 15: 3-4: 21, the molar concentration of 2,6-DCT was 2.4 % and the ratio of O/NH3 was 1. [1 %.]
The synthetic route of 118-69-4 has been constantly updated, and we look forward to future research findings.
