HCID 7253MethylhydroquinoneYield 45%

Procedure

In the same microreactor with the previous procedures there are charged 8.0 g amorphous BPO4 calcined at 170° C., 8.0 g hydroquinone and 7.9 g dimethylether, at a weight ratio 1/1/1. The hydroquinone conversion is 52% by moles, the yield to methyl hydroquinone 45% by moles and the selectivity to methyl hydroquinone 87% by moles. The gas-chromatographic analysis of the products gave the following result:

Workup

  1. customcalcined at 170° C.
