2-Methoxy-6- -1,4-benzoquinone

Treatment of 2-methoxy-1,4-benzoquinone with hydrogen chloride yields a highly colored compound formulated as the internal quinhydrone 167, which on further reaction with hydrogen chloride yields the dibenzofuran 168. 2-Methoxy-l,4-dihydroxybenzene is oxidized by 1,4-benzoquinone... 

The decrease in reflectance for irradiated 2-methoxy- 1,4-benzoquinone impregnated cellulose and mechanical pulp handsheets has been previously reported by Forsskahl (10). We have further explored this phenomenon and have examined the rate of reversion. As summarized in Figure 2, the rates of... 

Serendipiously, we have also found that 2-methoxy-1,4-benzoquinone impregnated cotton linter sheets undergo a slow thermal reversion process. The results of the thermal reversion data are summarized in Table 1.
